How to extend aluminum wire in the wall? — Window Guru's Handbook

Situations when it is necessary to connect or extend wires during the operation of electrical wiring occur in the following cases:

  1. If the electrical wiring is cut while drilling or tapping the walls.
  2. When moving sockets, switches and lamps without replacing power cables.
  3. If the length of the conductor in the installation or junction box after repeated re-wiring is not sufficient to connect it.
  4. Breaks in power cords of household appliances.

The correct way out of these situations is to replace the damaged section of electrical wiring or power cord. But as a temporary measure or in cases where replacing a section of wiring is not economically feasible, you can get by with making wire connections.

How to properly connect wires to each other in a wall

If you need to connect damaged electrical wiring in the wall of a panel house, then it is better to replace the damaged area with a new one. The conductors pass inside the cavities allocated for them and are not rigidly fixed.

Both ends of the damaged wire are found and disconnected. Then a new piece of wire is tied to one of them. The temporary connection is made securely and wrapped with electrical tape so that the edges do not cling to irregularities encountered along the way.

Pulling out the old wire, drag a new one in its place.

It is important that the material of the new conductor matches the material of the old one. If the wiring in the apartment is aluminum, then aluminum must also be used for replacement.

Instructions for connecting conductors in the wall

The connection of conductors in the wall is carried out as follows:

  1. We determine the direction of laying the damaged area.
  2. Turn off the power to the area being repaired.
  3. Along the axis of the cable laying, we cut the wallpaper to a length of 20 cm on both sides of the damage site. Use a spatula to remove the wallpaper from the wall and bend it to the sides. This will allow you to stick them back on after the repair.
  4. Using a hammer and chisel, we release the cable from the wall on both sides of the damage site by the same 20 cm. You can use a flat, dull screwdriver instead of a chisel. Do not apply strong impacts to avoid damaging the cable insulation.
  5. If one of the line conductors is damaged, separate it from the serviceable ones. To do this, we open the cable sheath or cut the flat wire (“noodles”) lengthwise. The core insulation should not be damaged, so be patient, careful and persistent.
  6. If all the wires are damaged, we cut the cable in both directions.
  7. We cut the cable cores into lengths depending on the chosen connection method. Connection by welding, soldering, crimping or using terminals is allowed.
  8. If the cable cores are made of copper, then when using ZVI terminals (also called nylon terminals), you will not need to insert a repair jumper. Having selected a terminal of the appropriate cross-section, use them to connect the ends of the wires.
  9. In other cases, you will need to install a repair insert. It uses wires of the same material and cross-section. There are two connections for each wire.
  10. Connections require sealing. If the wall is damp, touching it at the location of the uninsulated connection will result in an electric shock. Therefore, the contact point must be tightly wrapped with insulating tape, additionally placing heat-shrinkable or PVC tubes on the wires.
  11. We lay the wires in the groove and cover it with plaster. Until the solution has completely dried, voltage cannot be applied to the repaired cable due to the possibility of a short circuit.
  12. After the solution has completely dried, we paste the wallpaper back.

Features of conductor connection methods

A reliable connection method is welding . It uses a voltage of 12-36 V from a welding inverter or a homemade transformer. One wire (ground) is connected to the twisted wires, and the other to the carbon electrode. When the electrode touches the top of the twist, an arc occurs. It melts the wires and a metal ball appears at the end of the twist.

The result of connecting wires by welding

While reliable, welding also has a number of disadvantages :

  • you will need equipment: a welding machine or a homemade transformer, a carbon electrode;
  • difficulties with connecting aluminum conductors: aluminum is welded only in an environment of inert gases that prevent it from oxidizing.

The second most reliable permanent connection is soldering . But soldering aluminum is just as difficult as welding - you need special solder and flux. In air, this metal is covered with a film of oxides that appears instantly. Therefore, the principle of aluminum soldering is to dissolve the oxide and treat the wire in a flux environment.

There will also be difficulties when soldering old stranded wires. Each of their veins is covered with oxide, so before soldering you have to carefully scrape it off with a knife from all sides. It is better to tin it with solder fat; the use of rosin is ineffective.

Before soldering, the wires are thoroughly cleaned of oxides, dirt and soot. They are then twisted together and the resulting joint is tinned.

Solder connection

Soldering has a disadvantage - the connection is difficult to disassemble.

For crimp , connecting sleeves are used. These are thin-walled tubes of various diameters for connecting conductors of corresponding sections. The sleeves are made of copper or anodized (tinned), the latter are universal and connect copper and aluminum conductors.

The wire is inserted into the sleeve from one side to the middle, then pressed with special pliers or a press. Then another wire is inserted on the other side and pressed in as well. PVC tubes or heat shrink are first placed on the wires to insulate the connection. But fully insulated connection sleeves are also available.

Crimping twists with sleeves

The disadvantage of this method is that it requires a special crimping tool; pliers are not suitable for this.

The use of nylon terminals of the ZVI brand also poses difficulties when connecting aluminum conductors. Aluminum is a soft metal, and the connection in the terminal is made by pressing the wire against the brass surface with the end of a screw.

The tightening force must be commensurate with the plasticity of the conductor, otherwise it can be cut. Flexible conductors are connected to the FVI only after tinning or termination with a sleeve tip (sleeve). But even in this case, you can’t push too hard.

ZVI terminals and their application

There is an opinion that if the conductors are twisted together and a wire connection is installed on top of the twist, the connection is reliable. But the terminal block screws, on the contrary, loosen the twist and worsen the contact.

Therefore, the use of connections using nylon terminal blocks is functionally limited: you can temporarily connect or repair equipment with their help.

Although in modern lamps the connection is made only through the ZVI.

There is only one advantage of the method: it is cheap.

WAGO self-clamping terminals are considered the most versatile means for making contact connections. No shortcomings have yet been discovered. The connection occurs through a spring-loaded contact into which the conductor is inserted. The terminal contains a lubricant that protects the wires from oxidation. If necessary, the connection can be disassembled.

About WAGO terminals, read the article: “Which is better to choose, twisted or terminal block for connecting wires?”

WAGO terminal

Another way to connect wires is with PPE caps (insulated connecting clamp). The cap is screwed onto the twist, tightening it and at the same time insulating it. Lubricant is also placed inside it.

PPE caps

For more information about PPE caps, read “PPE caps for twisting wires. Electrician's advice."

If WAGO terminals are selected according to the cross-section of the wires being connected, then PPE and ZVI are selected according to the diameter of the twist. And since the twists come in different cross-sections, depending on the number of wires in them, installation work requires a set of terminals of different calibers.

How to extend a wire: basic methods, materials, expert advice

The process of extending wire is not an easy procedure, but anyone can figure it out. There are rules to follow. The sequence of all actions must occur with precision, because we are talking about electricians. Is it possible to extend the wires? Experts give a positive answer.

Which method should you choose?

Wires and cables have different designs and internal contents. The cores can be made of copper and aluminum. Winding - in one or several layers. The scale of the work performed depends on this. Before extending the wire, these nuances are taken into account. Experts say that theoretically it is possible to connect even cores of different metals, but this is for those who have experience.

Options

If access is good and the connection needs to be made of the same material, then it is important to use the following options:

  • Some inexperienced people may imagine the process of creating extensions literally. But today there are terminal blocks on sale. They are unique and can create elongation even for different metals. The procedure is simple, but it is better to see how it will look before starting work.
  • To avoid spending a lot of money, connector blocks are used. They are on free sale.
  • Twisting procedure. At first glance, the procedure seems simple, but if you do it carelessly, the design will quickly fail. When twisting is done carefully and competently, the period of its use is not limited.
  • Using a soldering iron. Soldering is considered the most reliable option today. This type of work requires special tools, experience and electrical understanding. Before you extend the wire using this method, you need to know the process itself. Even large sections of the main core can be soldered.

If you need to extend components from different materials, one of the best ways is to use a terminal.

Every job requires a tool, including for extending wires. There is no need to tell how a simple twist is made, which is simply fixed with electrical tape, because this method is not useful and is short-lived. You shouldn't do everything in a hurry. You can get an electric shock, and the electrical appliance will not work as it should.

To work you will need:

  • Sharp knife, side cutters. Using this, you will need to remove the winding to get the main cores to extend the entire structure. Before extending the wire in the panel, you need to turn off the current supply. Otherwise, it will not be possible to avoid injury or breakage of the main core.
  • Pliers or screwdriver. Thanks to them, it is easier to connect, push, and attach.
  • Insulating material.

Depending on the chosen method, everyone has the right to add to this list. Experts say that during the process of lengthening, problematic situations always occur. If you know how to get out of them, it’s easier to work.

What can happen?

Before extending the wire, everything is prepared - the winding is removed, and then you can see whether the core itself is made of such metal. At the same time, even at the level of design analysis, non-standard situations occur.

  • A vein broke in the wall. This is not uncommon. How to extend a wire in a wall? To understand how to proceed further, you need to determine the length of the existing wire. Because it happens that it does not provide the possibility of renewal. In such a situation, you will have to hammer the wall. If it is concrete or brick, you will need a hammer drill. With wood it is a little different - when the wire is extended, you will have to cover up the hole made. For this, a special wood putty is used.
  • Sometimes the cable runs in water. Of course, in every situation the wire is initially de-energized, only after that they work. Experts believe that even under such conditions it is worth wearing protective gloves on your hands. You will have to purchase heat-shrinkable pipe; the same option is suitable for underground devices. Extending aluminum wire is difficult. In this case, you cannot do without terminals. After increasing the size, a pipe is installed and then carefully heated. To do this, use a soldering iron or lighter. Slight heating occurs. It is important that in the end this protective system sits on the wire as much as possible (this is an opportunity to eliminate short circuits).
  • If the wire cross-section is large (up to 6 mm), one of the suitable methods is soldering. Any other option will bring additional problems during operation. Such appliances include a stove, air conditioner, heater, etc.
  • With devices of low power everything is simpler. For example, how to extend a copper wire from a washing machine? This question is difficult for people without experience, because such a unit has its own operating system. If you do something wrong, everything will simply fail. The most basic option is an extension cord.
  • What actions are taken if you need to extend a broken wire? Simple twisting is often used, but this is ineffective. Depending on the device, you take the instructions and use them to determine what needs to be excluded from the work. But the simplest option is to use terminal blocks. After which isolation is performed. Another serious situation is a twisted wire. How to work? It is necessary to connect and extend each system separately, not forgetting to make insulation.

Do-it-yourself works

It is worth understanding that any independent work that is done incorrectly leads to fire hazards. If you perform elementary twisting, oxidation will occur after a while, and then heating. You should not take risks and splice aluminum and copper wires. Only the terminal block allows you to create a high-quality connection and eliminate the connection of different wires.

Heat shrink tubing is an effective insulation. But it cannot be used everywhere, because slight heating has to be done so that it fits tightly onto the exposed wires.

Subsequence

The work process is simple.

  • The tube is put on.
  • After which you need to begin the process of connecting or lengthening the core itself.
  • Only when the work is completed should the tube be in the right place.
  • It is easily heated with a lighter (there are special burners).
  • Under this influence, it contracts.

As a result, the insulation was performed efficiently and without wasting a lot of time.

Complex cases

Before you extend an aluminum or copper wire, you should understand how long it is. It is clear that when it is short, you will have to hammer into the wall, but not everyone is ready for this. If you decide to break through the wall, you will have to clean everything up afterwards, and when the repairs were completed not so long ago, it is difficult to do this. Soldering and twisting are completely eliminated.

But there are special connecting blocks in stores. You can use such a system even on wires made of different materials. The work has its own stages of implementation:

  • Take any tool to strip the wire that sticks out of the wall. After which the wire is well cleaned.
  • One end of the block should be on the wire.
  • It is tight, so it is not so easy to do this procedure. But if you try, everything will work out. It will take less time than punching through the wall and extending the end of the cable.
  • The same is done with the second end.

Both wires must be fixed as tightly as possible; there should be no flyout. This option is simple and accessible to everyone, even a beginner. The store has a lot of different pads from manufacturers from many countries. It is clear that products from China will not be of high quality.

Conclusion

So, we found out how you can connect the wires with your own hands. When performing such operations, you should always remember that working with electricity is unsafe. It is worth checking that the wire requiring increase is de-energized and is not capable of striking.

Doing soldering with your own hands is not so easy, as already noted. In this situation, it is important to choose the right soldering iron. It must be thin, otherwise nothing will work.

The substance that will be used to carry out the process of riveting and elongation should also be chosen, taking into account what material the core itself is made of.

How to increase the length of the wire from any electrical appliance so that it is not noticeable?

Surely each of us has one or another electrical appliance at home, which today is difficult to do without. This could be a TV or a microwave oven. In general, everything that runs on electricity. Of course, such devices make our lives easier and it’s hard to imagine how we can do without them today.

But strangely enough, it begins to seem that developers who plan the location of sockets or manufacturers of electrical appliances who make very short wires are plotting us. You've probably noticed that the cable from an electrical appliance is not always long enough to reach the outlet. Of course, you can use an extension cord, but then all the wires will get mixed up, and the aesthetic appearance of the room will be disrupted.

THIS IS INTERESTING:  How to calculate the mass of a steel pipe

You can extend the wire, it will be noticeable and will look, to put it mildly, not very beautiful and aesthetically pleasing. But what if we tell you how to extend a cable without a visible twisting effect? As it turned out, such a method exists, and experienced specialists decided to reveal this secret as simply as possible.

What is required to extend the wire?

The procedure is quite simple, but in order for everything to go as smoothly and beautifully as possible, you need to prepare the necessary tools and materials. So, we need:

  • Nippers or metal scissors;
  • A stationery knife (you can take a kitchen knife or any other knife, the most important thing is that it is sharp);
  • A roll of electrical tape;
  • A piece of cable suitable in cross-section diameter and color;
  • Heat shrink tube to match the cable color;
  • Lighter.

Finding all this will not be difficult. Almost all of this can be found in any house or apartment. Of course, not everyone has heat-shrink tubing, but you can buy it at any hardware store at a reasonable price.

Extension procedure

When you have everything prepared, you can start building up. The procedure is very simple, the main thing is not to rush and do everything carefully. To make everything much easier, you can follow the instructions:

  1. First you need to use wire cutters or scissors

    cut off the plug from the wire. You need to step back one centimeter from the base of the fork and make a cut.

  2. Now we clean the edges of both ends of the wire. Each wire contains two cores, which also need to be stripped of their braid. To do this, you can use a knife to quickly release the exposed copper wires.
  3. Once the wires are exposed, you need

    tape the end of the plug to a new piece of wire (one that will suit your needs and will easily reach the outlet)

    in a certain sequence. In fact, everything is as simple as possible. Bright wire - it will always be

    a plus, and light or black will be a minus. For example, on your plug one wire is red and the other is green, but on a piece of wire there is only a yellow and a white wire. This means that red and yellow will be plus, and they need to be twisted together. In this sequence, you need to secure the minus to each other.

  4. Now the second end of the piece of wire can be wound with the part that goes directly to the electrical device.

    But before that, you should put two

    heat shrink

    tubes that we will not touch for now.

    The sequence is exactly the same.

  5. When both wires are secured on both sides, they can be securely insulated

    so that they do not touch each other with exposed wires.

  6. Now in place of each twist we pull

    heat shrink

    film and

    heat it with a lighter. It is important not to overheat the film and keep the lighter not at close range.

Once the film is warm, you can press it firmly onto the wire and no one will be able to see that you have extended the cable.

How to extend or connect an electrical cable

Breaking an electrical wire can create quite a significant household problem. Therefore, the question of its possible restoration becomes incredibly relevant.

In some cases, there may be an urgent need to extend an existing wire.

Most often, the need to extend or connect cables arises in the following cases:

  1. While working with an angle grinder, you “managed” to stumble upon a wire embedded in a wall or floor and accidentally cut it. As a rule, such a situation is accompanied by a mass of sparks that occur at the site of damage. The machine installed in the electric meter will immediately turn off or knock out the plugs. In addition, all sockets connected to this section of electrical wiring will immediately be de-energized, and the lighting in the apartment will disappear.
  2. A wire carelessly laid by craftsmen in a wiring box or under a switch can also break off. In this case, the remaining length for connection is not enough.
  3. With the purchase of a new or rearrangement of an old electrical appliance, there is a need to move the existing outlet.

The optimal way out of this situation should be considered a complete replacement of the damaged area. In this case, you will have to replace the entire wire connecting the junction box and the outlet (switch). Carrying out such a procedure very often involves gating, which means inevitable damage to a large adjacent section of the wall. In addition to the wire itself, you will most likely have to replace part of the tiles, plaster or wallpaper, which is not always acceptable.

How to connect an electrical cable

Some citizens consider the simplest solution to the problem to be primitive twisting of damaged wires together and further wrapping them with ordinary electrical tape.

This method is not only incorrect, but also quite dangerous, since it is impossible to create reliable contact in this way. The twisted area will certainly oxidize over time and will constantly heat up!

You can carry out reliable restoration or extension of electrical wires on your own. When performing a similar procedure, you should remember that reliable contact is only possible when connecting wires of the same metal.

It is possible to connect conductors made of aluminum and copper only in the terminal block, since only in it the wires do not touch when connected. In all other cases, copper and aluminum wires should not contact each other. They cannot be twisted or crimped. Otherwise, at the point of contact, these wires will begin to oxidize, and the electrical contact will disappear.

Quite often, to connect wires in electrical panels, differential circuit breakers or RCDs are installed, which are triggered when a current leak appears in the electrical network. In such a situation, it is necessary to qualitatively insulate the phase, neutral and grounding conductor from each other.

The use of a special heat-shrinkable tube can guarantee high-quality insulation. It is first put on the wire and placed at the junction after extending the wires or connecting them to each other. To finally shrink such a tube, it should be heated using a gas burner, a special hair dryer or a simple lighter. The heated tube will shrink and can make the joint airtight.

If there is high humidity in the room where the wires are connected, then soldering or welding should be used to create reliable contact. The insulation of such connections should be performed at least as high quality.

If the electrical cables used to connect the electric stove have a cross-section of 4 or 6 square meters. mm, then they should be connected only by soldering.

One or even several wires may break off in the installation box, thereby complicating the installation of the socket and switch. If the length of the remaining ends is at least 1.5 centimeters, then to extend them it is best to use a terminal block (in the lower picture on the left). Both wires need to be thoroughly cleaned, and they must be inserted into the terminal block and tightened with a screwdriver one at a time.

It may turn out that the wire is not long enough. In this case, the section up to the box must be split to extend the socket to the new cable section. The connection of the wires is carried out in the same way as when restoring a damaged cable.

To weld the cores together, it is best to use a special factory-made apparatus.

If the cable cores are painted in different colors, then only wires of the same color should be connected. This will greatly simplify the procedure for connecting the grounding conductor to the outlet.

Instructions for restoring or extending the cable

In order to restore the integrity of a broken or cut electrical cable, you must strictly follow the instructions below:

  1. In all panel houses, the electrical wiring is laid inside the pipes, so additional gating is not required. The damaged cable should be pulled out of the channel and replaced with a new one from the socket to the junction box.
  2. Sometimes, in order to reliably place an insulated cable connection, you should break a section of the wall along the cable 15 centimeters in both directions. In this case, the depth of the split should be taken with reserve. This procedure must be performed carefully. Otherwise, the cable may be damaged again.
  3. The cable needs to be cut and its ends cleaned. This must be done at different distances so that the places where the bare connections of zero and phase are not located opposite each other.
  4. We take wires of the same metal and the same cross-section as in the damaged area. We put cambrics or heat-shrinkable tubes on them. The wires should be connected to each other by welding, sleeves followed by soldering or self-clamping terminal blocks.
  5. It is necessary to stretch the heat-shrink tube over the exposed areas of the connections and heat it.
  6. If heat-shrinkable tubing is not used, the wires should be individually rewound with high-quality electrical tape. Although the electrical insulating properties of self-clamping terminal blocks are quite high, it still doesn’t hurt to wrap them with additional electrical tape. This rule applies to places where solution can get inside the clamps.
  7. The section of the wall where the electrical connections are located must be covered with plaster solution and leveled.

How to extend short wires in a switch without soldering or replacing wiring

Apartment renovation means new wallpaper, new switches and sockets. If the wiring is aluminum, then difficulties arise when replacing electrical accessories. When a socket (switch) is removed, the wires are broken off. Professional electricians extend them by soldering. Home craftsmen prefer another method. To solve the problem, they use terminal blocks (terminal blocks).

Types of terminal blocks

Terminal blocks are mounting accessories that are used for connecting and extending wires: aluminum + aluminum, aluminum + copper. Copper and aluminum wires do not oxidize if they are connected with a screwless terminal connection from WAGO. Thanks to a special paste, the conductors do not contact each other.

Electrical fittings consist of a housing made of plastic, metal sockets or plates, and a screw connection. The exposed parts of the wires are inserted into the sockets, the screw is tightened, and a strong connection is obtained.

A home handyman does not need special knowledge or complex tools to install wires in a switch. The following terminal blocks are suitable for installing a new or replacing an old plug connection:

  • Legrand (screw);
  • WAGO (screwless).

Replacing a single socket with your own hands

To install hidden sockets, a hole is drilled in the wall into which the socket box is inserted. A power cable is inserted into it. During the cosmetic renovation of the apartment, the old socket is dismantled and a new one is installed that meets the requirements of GOST 7396.1-89.

What tools will you need?

To install the decorative body evenly, you need a level. It makes it easy to draw vertical and horizontal lines on the wall. If the fittings are installed after wallpapering, then a construction knife is needed. They use it to cut the wallpaper around the perimeter of the socket box. To remove the insulation you will need side cutters (nippers). You also need 3 types of screwdrivers:

  • regular;
  • indicator screwdriver;
  • Phillips screwdriver.

Algorithm

Before dismantling the old outlet, the network is de-energized - the machine is turned off. The absence of voltage is checked with an indicator screwdriver. When there is no phase, the indicator light does not light. Use a Phillips screwdriver to unscrew the screws and remove the old housing. Pull out the power cable. It has 3 wires (phase, neutral, ground) and 2 layers of insulation:

The color of the wires is different: zero - blue, phase - brown, ground - green. First, remove the outer insulation with wire cutters, then strip the ends of the conductors. When using WAGO terminal blocks, the insulation is removed by 1.5 cm.

Important!

General insulation is removed 2 times more than internal insulation.

At the next stage, they are working on a new socket. It consists of 2 nodes:

  • decorative box consisting of a front panel and a frame;
  • block, consisting of a housing, contacts, terminals, and mounting tabs.

To connect the wires you need to gain access to the terminals. To do this, the socket is disassembled. Use a screwdriver to unscrew the screw that secures the housing. The next step is basic. The wires are connected to the socket.

During installation, the cable is positioned so that the conductors inside the housing do not touch. If the terminals in the socket are screw, the wire is first bent into a ring, then the screw is tightened, this improves contact. In models with screwless terminals, the wire is inserted into the terminal until it clicks.

At the last stage, install the socket. First, attach the block, controlling the position of the fastening tabs. They must be positioned strictly parallel to the floor line, then the decorative panel will be installed correctly.

Note!

With modern plug-in models, mounting the front panel takes seconds. The places where you need to press with a screwdriver are marked on the body. Old-style products are screwed on with a screw.

New sockets are installed according to the same scheme. Their number in the apartment is calculated according to the standards. In a living room you need one for every 4 m², in the corridor - 1 for every 10 m². To install them, in addition to screwdrivers and wire cutters, you will need a hammer drill, a drill, and a crown.

Products from ABB, Shneider electric, Legrand, Siemens fit perfectly into the interior of the apartment. Their advantages: durability, high-quality contacts, modern design.

Which car cigarette lighter wires are best to choose for use in winter and why?

The presence of wires for lighting the car in the on-board equipment kit is desirable in the following cases:

  • operating a vehicle at extremely low temperatures;
  • significant wear of the battery;
  • Difficulty starting the engine when cold.

Experienced drivers know that when asked to “light” a car, the most likely reason for failure is “lack of wires.” Therefore, it is better to have wires for lighting in the trunk of your own car.

Purpose

The main purpose of the cigarette lighter wires is to provide the ability to start the car engine when the charge level of the standard battery is low.

Some car enthusiasts, having no wires, remove their battery, put in its place the battery from the donor car or another charged one, then after starting and warming up the engine a little, remove the terminals while the engine is running, and reinstall the standard battery. This is an extremely dangerous operation for the following reasons:

  • if the car’s generator produces increased voltage, at the moment when the battery terminals are disconnected while the engine is running, abnormal voltage is supplied to all electrical equipment of the car, which can damage electronic control units, lighting, and other devices;
  • “free” terminals at the moment of switching the battery can lead to a short circuit;
  • Operations of turning off and on the battery increase the likelihood of polarity reversal of the battery, both the standard one and the donor vehicle, which is extremely dangerous;
  • Removing the battery terminals can lead to problems with the immobilizer, security alarm and car radio settings (again, on two cars).

Therefore, it is not recommended to use the method of starting the engine with reinstalling the battery.

How to “light” a car correctly

In the case when the charge of the standard battery is not enough to start the engine, you can use the cigarette lighter wires and start the car from the donor car.

Sequencing:

1. Carry out an external inspection of the cigarette lighter wires.

Assess the correspondence of the color markings of conductors and probes. Typically, positive terminals are served with red clamps and conductors, negative terminals are served with black ones.

If the conductors are not color-coded (or the same color), check that the conductor goes from the red (positive) terminal to the same one at the opposite end. If the wires are homemade and not color coded at all, you must be extremely careful when connecting them so as not to confuse the polarity.

2. Estimate the cross-sectional area of ​​the conductors.

This can be done visually in the area of ​​connection with the clamps. The maximum current flow is considered to be 8 Amperes per 1 sq. mm. cross-section of conductor with copper core.

The calculation takes into account only the cross-sectional area of ​​the copper core, and not the conductor as a whole along with the insulation. There are cases of Chinese wires with a total thickness of “a finger”, in which the copper core has a thickness of “a hair”.

With a car starting current of 200 Amperes, the cross-sectional area of ​​the core should be at least 25 sq. mm. If you divide by 3.14, then the diameter of the conductor core must be more than 8 millimeters. If the wires are in the original packaging, the starting current limit is usually indicated on it. If it is less than expected, you will have to “tighten up” the standard battery in order to start from two batteries.

3. Assess the quality of the clamps, the place of connection with the battery terminals.

Do not connect clamps with bare conductors connected to the battery terminals. This may cause the wiring to become charred. The clamps must be connected to the metal parts of the terminals.

4. Go to connecting clamps.

First, connect the positive wires. First of all, connect the clamp to the “+” terminal of the standard battery, then to the “+” terminal of the donor car battery. After this, connect the negative clamps of the battery terminals.

Why in this order: if you connect the negative clamps first, while connecting the positive clamps, it may slip and fall on the car body. This will cause a short circuit.

When connecting the terminals, you should not rush; you need to check the connection polarity three times and double check the quality of the terminal connections, so that after startup the clamps do not fall off, especially the positive ones. If you have “free” hands, it is better to hold the clamps.

5. The engine of the donor car is started.

Within 5 – 10 minutes the standard battery is “tightened up”. At this time, it is charged from the generator and the donor car battery.

This operation (recharging the standard battery) must be performed, otherwise the current from the power supply system of the donor vehicle alone may not be enough to start the engine, especially since at high currents on the cigarette lighter wires there may be a voltage drop of 3 Volts or more.

6. Next comes the controversial point..

Some owners of donor cars (especially taxi drivers) turn off their car and turn off the ignition when starting the standard engine.

In principle, they do it correctly - to reduce risk. If there is a possibility that the vehicle being started has a malfunction of the generator, wiring, or other electrical equipment, this can cause significant damage to the donor vehicle. This is how we can come to an agreement.

But it is better if, at the time of starting the standard engine, the engine of the donor car is running; even better, slightly increase its revolutions with the accelerator pedal to 3,000.

7. Make a short attempt to start the engine.

At this time, carefully monitor the ignition wires. If they start to heat up or change shape, stop running immediately.

8. In case of unsuccessful start-up, check how much the temperature of the terminals of the cigarette lighter wires and conductors has changed.

Try to start again after 3 – 5 minutes. Subsequent startup attempts are made at intervals of at least 10 minutes. The total number of attempts should not be more than 7 - 10. After this, it is better to leave the problem of starting the engine and try to charge the standard battery on a stationary charger.

how to “light” a car correctly:

Selecting wires for lighting

On sale, including at gas stations, there is a wide selection of wires for lighting a car. Since such a purchase is not made for one day, it is better to purchase a universal, reliable model that will last for many years.

Next, read the main recommendations and what parameters you should use to choose them.

1. Length

Do not try to buy wires of the maximum length. The longer the conductor, the more the voltage across it drops.

If at 1 meter of conductor the voltage drop is 0.5 Volts (at high starting currents this is possible), then at 3 meters the drop will be 1.5 Volts. Considering that there are two wires (positive and negative), the total voltage drop will be 3 Volts.

If the donor car’s battery has 13 Volts, then only 10 Volts will reach your own car, which may not be enough for a stable start.

The length of the wires depends on the installation location of the standard battery. If the battery is located in the passenger compartment or trunk, there must be a powerful terminal under the hood to start the car in emergency mode. It is usually located under the red insulating protection and is indicated by a “+” symbol.

The normal universal length of the cigarette lighter wires is from 2.0 to 3.5 meters.

To ensure that they are enough to light a car in the garage, experienced drivers place the car with the hood facing the gate. If the battery is located under the hood on the passenger side, the length of the wires for lighting should be longer, since it is likely that it will be more problematic for the donor car to drive close to the location of the battery, especially on the highway.

2. The cross-sectional area of ​​the wire for lighting a car

The minimum cross-sectional area of ​​the current-carrying wire is 16 sq. mm. In terms of diameter, this is about 5 millimeters (half a centimeter). Wires with a smaller cross-section will heat up and have a large voltage drop across them.

Chinese manufacturers save a lot on wire cross-section. In pursuit of reducing costs (copper is very expensive), they significantly reduce the thickness of the cores, trying to hide this fact behind the large thickness of the insulation. It is better to purchase wires from Russian manufacturers. A cross-sectional view of a Chinese wire that is not of the best quality can be seen in the picture below.

3. Material of wires, insulation and alligator clips

Typically, current-carrying conductors are made of copper stranded conductor. Copper also comes in different qualities and production technologies. For example, speaker wires are manufactured using seven different technologies. For lighting wires, the technological features of the manufacture of conductors are insignificant, so they use a more budget-friendly quality.

Aluminum has a lower resistivity, and from this point of view it is better suited for conductors. But there are two significant disadvantages: it is brittle and fusible, so it is not used in factory-made cigarette lighter wires.

The insulation is usually made from soft polyvinyl chloride (PVC). It is difficult to judge its quality by its appearance. The packaging may indicate the operating temperature range. At temperatures less than minus 30 degrees Celsius, poor PVC insulation can crack, rendering the wires unusable.

Alligator clips can be made of steel, copper, brass, bronze. The best option is undoubtedly copper or brass. In the case of steel, there will be greater contact resistance on different materials, electrolysis processes increase (the wires become covered with a green or white coating). Bronze, especially thin bronze, is more brittle. There are good combination clamps made of steel with copper “teeth”.

How to choose starting wires from the options offered on the market

The following model can be classified as a type of ultra-low-cost cigarette lighter wires:

The declared cross-sectional area is 9.6 sq. mm. will provide a starting current of no more than 100 Amps, and not 200 Amps, as indicated on the packaging. Such wires cost about 500 rubles.

The following wires are a little better, but even here the terminals leave much to be desired:

They cost from 1000 rubles and above.

Better quality cigarette lighter wires look something like this:

Their cost starts from 2,500 rubles, they are designed for inrush currents up to 1000 Amperes, the weight of wires 5 meters long is about 4 kilograms. You can also judge the quality of the wires by weight. The insulation weighs almost half as much as a copper core. This model does not skimp on the crocodile material either.

how to choose wires for lighting a car:

Wires for lighting yourself

You can make a set of wires for lighting a car yourself. Usually they are made independently by those car enthusiasts who have access to inexpensive components.

For this you will need:

  • two stranded copper wires with a cross-section of at least 25 sq. mm and a length of at least 2 meters with PVC insulation of different colors (preferably black and red);
  • side cutters or a sharp knife for stripping insulation;
  • powerful soldering iron (from 60 Watt), POS-60 solder, active flux for tinning and soldering;
  • insulating casing or heat shrink to insulate the junction with the clamp;
  • pliers;
  • 4 heavy duty copper or brass alligator clips.

However, such usual variants of crocodiles cannot be used !

The process of making homemade wires for lighting is simple:

  1. The PVC insulation at the ends of the wires is removed to a distance of approximately 1.5 cm.
  2. The copper wires and the soldering points of the clamps are tinned.
  3. Using pliers and a hammer, the wires are secured to the clamps.
  4. The places of electrical contacts of the wires with the clamps are sealed. With high-quality crimping of the contact point, soldering does not need to be done; it is of secondary importance, since at high currents and heating it can be destroyed. In high-quality wires, the electrical connection is secured by spot welding.

General recommendations

Be sure to purchase or make cigarette lighter wires if the standard battery has moderate or severe wear.

Don't buy cheap low-quality wires, they won't help you.

Store the wires in a plastic bag unless a special bag is included in the sales package.

Be careful when connecting wires; the slightest mistake can lead to big problems.

How to extend a wire in a socket, wall, outdoors, for an input power cable or electrical appliance

When making repairs, people often wonder how to extend the wire. It’s not surprising, because when updating your home, you always want to move something and change places. At the same time, the wiring in a modern apartment is very diverse, which confuses a person even more when choosing a method for installing it.

Extension means increasing the length of a cable or individual wire. This connection is made not only mechanically, but also electrically. The resulting contact should be as strong as possible and have minimal contact resistance. This is a mandatory requirement for power wiring and input cables.

Wire extension technology

Basic methods of cable extension

There are many ways to extend wiring. They differ in the reliability of contact and complexity of implementation. Most electricians practice the following methods:

  • extension using WAGO terminals;
  • terminal blocks with screws for tightening;
  • classic twisting of cores;
  • soldering with tin solders (for copper wiring);
  • welding of cores with a graphite electrode;
  • connecting sleeves;
  • electrical nut;
  • extensions using Scotchlocks.

Scotch tape for connecting wires

Additional Information. The connection method is determined by the material of the wire and the current that flows through it. For high powers, soldering and welding of cores is ideal. Low-current circuits can also be connected in other ways. But if this is a high-frequency signal from a TV or Internet cable, then the connection point is made as compact as possible and without kinks.

In what situations do you have to extend the cable?

Usually, extensions are resorted to when the wiring is accidentally damaged. For example, a man was drilling a wall and using a drill he broke a lighting cable walled up under the plaster. No one is immune from this.

Another case. It is necessary to increase the length of the solid cable. In such a situation, the conductor is deliberately divided into two parts. Then a new piece of wire of the required length is wedged between them.

The easiest way to build up. Old-fashioned method

The simplest of the listed methods of extension is the classic twisting of cores. The wires must be made of the same metal and preferably of equal cross-section. The procedure for building up is as follows:

  1. Using a knife, remove 30-50 mm of insulation from the ends of the connected wires.
  2. Twist the stripped wires together along the entire length of the exposed areas. The connection is made as tight as possible.
  3. Wrap the resulting twist with insulating tape.

Additional Information. If the cable length for a TV, computer and various office equipment is not enough, then it is not necessary to extend them. Typically, these wires are standard and available at a consumer electronics store. And the length that suits you.

Extension of wires going to the outlet

It is necessary to extend the wires for the socket, for example, when moving it closer to the floor under the European standard. It should be remembered that powerful consumers of 1.5-2 kW can be connected to the outlet. Therefore, twisting must be done efficiently. It is recommended to use the following connection methods:

  • welding;
  • soldering
  • connecting sleeves;

Other extension techniques are also suitable. But their reliability and safety do not inspire confidence (we are talking about powerful consumers).

Copper conductors

It is easier to extend copper wire than aluminum. Three methods are suitable: welding, soldering, sleeves. Before connecting, the insulation must be stripped from the cable.

Welding is performed with a special transformer. It is expensive. It makes sense to purchase it for practicing electricians.

Soldering is done using an electric soldering iron, solder and rosin. A cheap way available to everyone. However, it requires minimal skills in working with a soldering iron.

Soldering copper wires

Sleeving (crimping) will require the purchase of a crimping press. The method is suitable for professionals who are willing to spend money on purchasing expensive tools.

Aluminum conductors

Aluminum cable is brittle. Keep in mind that it will easily break if bent repeatedly. The cores can be welded using a transformer with a carbon electrode. A gas burner will also work, but it is more difficult and dangerous.

Sleeving is also suitable. The connecting tube must be made of the same material as the cable core. Aluminum wire cannot be soldered with a soldering iron and solder. Molten tin will not be able to “stick” to the surface of this metal.

Crimping of aluminum wires

Extension of other types of wires

Apartment wiring is not limited to sockets, power input cables and lighting. Sometimes you have to deal with other electrical circuits. Therefore, it is necessary to know the nuances and technology of building all possible types of wires.

The putty wire broke

This happens on the section of cable where it exits from the concrete wall into the outlet. If the wire sticking out of the cement is at least 15 mm long, then you should try to extend it using one of the methods described above. More often it happens that the core breaks directly in the wall. In this case, you will have to pick up a hammer drill and clear the wire from the solution to get an end accessible for work.

Extending and relocating the power input cable

Extending the input cable in an apartment is a responsible job. Therefore, you will have to resort to welding. This connection method is the most reliable and nothing better has yet been invented.

To weld power wires, a special transformer with a graphite electrode is used. It produces a high current of 100-150 amperes. If there is no transformer, then it is permissible to use a portable inverter-type welding machine.

Before connecting the wires, they should be twisted tightly. Then mark the individual wires.

Electrical wiring welding machine

Wiring for high-power electrical appliances

Powerful consumers of electricity are capable of drawing high currents from the network, up to 10-15 A. Examples of such devices: electric stoves, kettles, irons and various stoves. Copper cables are used for connection and extension. When performing work, the following conditions must be observed:

  • cross-section of cable cores is at least 2.5 square meters. mm;
  • twist connection by welding or soldering;
  • use of fabric insulating tape with non-flammable impregnation.

How to do extensions outdoors and in the rain and snow

Sometimes it becomes necessary to extend a wire located in the open air. This could be a SIP cable for powering an extension in a country house or lighting in a garden. In this case, special attention should be paid to sealing the joint.

Cloth tape will not work. Unlike PVC, it is able to absorb moisture from rain. It is convenient to use heat shrink tubes for sealing. Especially those that contain an adhesive layer inside.

Connecting sleeves for SIP cables with heat-shrinkable sleeves

Temperature sensor wires

If a thermocouple or digital three-wire meter is used as a temperature sensor, it is important to maintain the polarity of the connection. Extension wires are usually made of brittle alloys based on aluminum, chromium and copper. For connection it is possible to use simple twisting, screw or WAGO terminals. Soldering may not work. Depends on the specific type of alloy from which the wires are made. By the way, they are thin. Therefore, sleeves and nuts disappear due to too large sizes.

How to extend LED strip

It happens that after installing the LED strip, its brightness is not enough. Therefore, the lighting will have to be increased. When extending the LED strip, you should remember three basic rules:

  1. When connecting a new fragment, it is necessary to maintain polarity. That is, plus and minus. Usually these are red and black or gray and white wires, respectively.
  2. The LED tape is cut in special places. They are indicated by the scissors symbol.
  3. If the LEDs are RGB type, then there are four wires. They should be connected according to color coding. Red to red, green to green and so on.

Connector for extending LED strip

Twisted pair extension

A standard twisted pair cable contains eight wires. They are connected according to colors. The wire strands are thin and copper, so the best connection method is soldering with tin-lead solder. The grandfather's twist is also suitable. However, at high Internet connection speeds this can create problems. It would theoretically be possible to use sleeves and terminal blocks, but in reality it would be expensive and pointless.

Important! When extending signal and antenna wires, you should remember that they have a shielding layer. It is made in the form of copper or aluminum braiding in the outer layers of insulation. Its task is to protect internal conductors from interference. The screen is also subject to electrical connection. This rule applies to UTP wires for the Internet, audio and television cables. If the image ripples, then you should check the integrity of the screen up to the antenna.

Twisted pair connector

Connection of copper and aluminum

It is advisable to avoid such extensions. The best option for connecting copper to aluminum is terminals. Some models contain a special lubricant designed to increase the reliability of the contact and protect it from oxidation.

THIS IS INTERESTING:  How to add a wire to a twist

This connection is made accessible for inspection. It is not recommended to pass large currents through it. When making calculations, it is advisable to select them a step less than the permissible cross-section. If the wire is rated for 16 amps, then you should not pass more than 10 A through it.

General recommendations for extending wires

Below are general recommendations for adding wiring yourself. They will help simplify electrical installation work and avoid problems in the future:

  1. The extension wire must be suitable for the permissible power. Ideally, the cable cross-section is selected with a margin.
  2. The insulation must not be damaged or cracked.
  3. If space allows, it is advisable to leave some reserve. A cable that is too long is more convenient than a short one.
  4. Wiring should not rest on sharp corners. She can get over them.
  5. Avoid exposed live parts and contact with construction mixtures.
  6. The PUE prohibits the use of twists, so it is advisable not to perform them.
  7. All work is carried out with an insulated tool and stress relief.

Any twist or branch is a minus one point to the reliability of the wiring. You can lengthen the electrical cable when there are compelling reasons for this. In most cases, it is preferable to replace the entire wire without unnecessary cuts.

If build-up is inevitable, then the twist must satisfy two criteria. Firstly, the contact is strong and reliable, especially in power circuits. Secondly, the junction is isolated. The absence of a protective layer can cause a fire or electrical injury.

How to extend a short aluminum wire in a wall? — Website about

Hello dear readers! In this article I want to tell you how you can lengthen the wires in a socket or switch. There are times when we are dealing with internal aluminum wiring - this is a breakdown of the wire in the socket or switch box.

Meanwhile, such a situation can cause a lot of undesirable consequences for our budget. There is no way to connect anything to short wires; simply extending them roughly by screwing the wire is dangerous and even prohibited. The only way out is to move the point or change the wire.

People find different solutions, for example: they use a box for external wiring.

But judge for yourself - if you have only one external wiring box for all the rooms with internal wiring - what will it look like? You can trench the wall and replace the wire, but this option is only suitable if your apartment renovation is still ahead.

In this case, it is better to completely replace the aluminum wiring with copper wiring. But let’s return to the situation when we are replacing an outlet or switch during a repair that has already been done and we don’t want to disturb anything.

The only sure way is to build up an aluminum wire in the socket

The way to solve the problem is to solder aluminum wires. It is known that you can easily solder copper wires, even after stripping them with rosin. What about aluminum? Yes, rosin in this case is a useless material.

In modern conditions, construction stores sell a special flux for soldering aluminum. You can use connecting pads, but there are two disadvantages.

Firstly, there is not enough space to hide them and it will not look neat, and secondly, the connector cannot be compared with proper soldering.

How to properly solder wires with a soldering iron?

We first check the wires by tension. If the wire is really broken, when the insulation is pulled, it easily comes off. There is about a centimeter of wire left. We will connect a copper wire of the same cross-section to the aluminum wire. You need to use F-64 flux for soldering, which is ideal for the aluminum-copper combination.

First, you should strip both the aluminum wire ends and the copper wire blanks. Then we wind the copper wire onto the remaining piece of aluminum wire.

But we do this by first winding a copper piece of wire onto a wire of a larger cross-section, and then sticking it out, leaving it in the form of a spiral so that we can then put it on the wire stripped in the wall.

It is important that we leave a little insulated wire in the remaining piece.

We prepare the cambric and put it on prepared copper blanks for our aluminum wires. We have ready-made blanks for soldering.

We insert the blanks into the wire in the wall. It fits in easily, since we previously wound the copper wire onto a wire of a thicker section. The next step is to drop 1-2 drops of flux onto the joint and, using a heated soldering iron, heat this section with flux together with the tin solder.

It is necessary to take into account the fact that flux does not function well with an overheated soldering iron; it is important to prevent overheating. The last step is to stretch the cambric and strip the copper wires for the socket or switch.

In conclusion, it should be noted that copper wire will not be as brittle as old aluminum wire and this way several problems are solved.

How to extend a wire at home

» Electrical wiring » Wires and cables » How to build a wire at home

In this article we will talk about how to extend the wire at home. As a rule, many people sooner or later encounter this problem. Nobody knows how to fix it, I decided to make a detailed description for you to remove all the questions. And talk about all the situations and ways to get out of them.

How to extend a wire: basic methods

Here we will talk about the simplest extension of wires, when there is full access to the wire and the cores of the conductors are made of the same metal. Such methods are suitable for both copper and aluminum wires.

  • WAGO terminal blocks. They can be used even in cases where the metal does not match. It is very easy to extend wires using them. For clarity, I will show you an image, so it will definitely be clear.
  • Connecting blocks for extending wires are the most budget option.
  • Twisting of veins among themselves. This method cannot be called safe, but if done correctly, such an extension will serve you for a lifetime. But remember, you need to twist carefully.
  • Soldering is the optimal and best option. But, it is only suitable for experienced electricians. In this way, you can even extend wires with a cross-section from 4 to 6 mm.

Remember, you can only connect a copper wire with an aluminum wire using a special terminal.

Read the classification of wires, not everything can be extended.

And so, here we have discussed the main methods with you. Watch the video, it will be even clearer to you.

Now let's talk about situations that may arise. Standard methods are good, but you need to be able to get out of any situation. I’ll tell you about all the situations.

A vein in the wall broke

If this happens, you must decide whether there is enough wire to connect everything. If there is enough, then we use any method that you might have seen before. If it’s broken so you can’t get under it, you have to break the wall and carry out all the actions there.

How to extend cable in water

This situation arises in cases where it is necessary to lengthen a section of cable running in water, for example: to increase the wire for a submersible pump. Here you will need heat shrink tubing. We do everything only as shown in the picture. This method is suitable for underground cables.  

Remember, you can heat it with a lighter, but make sure that the tube must fit tightly onto the wire.

How to extend a wire or cable to power powerful electrical devices

In this case, only one option is suitable - soldering. Don't even look at others - it will only bring trouble. Powerful electrical appliances include: air conditioning, electric stove, etc. The conductor cross-section should be (4mm).

How to extend a cable or cord of low power

For example, if you decide to extend the cord for a microwave or washing machine, throw this idea out of your head. After all, if you connect it incorrectly, there will be big problems. And you can mistakenly connect the grounding with the phase. In this case, it is easier to stretch the wire under the baseboard, and safer.

Increase the length of the temperature sensor wire for heated floors

Initially, read the instructions for it, if there are no problems, use the terminal blocks.

How to extend twisted pair

In this case, there are no problems, but remember, you need to build up each vein separately. Don't forget to carefully insulate the wire extension area.

All existing methods of extending wires under water or in an apartment: how to extend the cable under different conditions?

Extension of wires occurs by increasing the length with another conductor. There are various ways to extend cables, which are used depending on the operating conditions, technical characteristics and parameters of the devices.

How to properly extend a wire

There are situations in everyday life when it is necessary to extend a wire or replace a non-functional section of cable.

The procedure is not easy, but by following the instructions and observing safety requirements, you can do the extension yourself step by step.

What is extension?

Cable extension is called extension of electrical wires. The increase occurs by connecting the cable to another wire of the required length. Conductors can be extended in various ways. The new piece of cable must have the same technical characteristics as the original conductor.

The length of the cores must be increased in accordance with the instructions. If the work is performed poorly, there is a risk of unreliable fixation, contact overheating, conductor fire, and short circuit.

The general technology for increasing length is as follows:

  • a conductor with the same characteristics as the original one is purchased;
  • the connection method is selected according to the technical parameters of the cable and its operating conditions;
  • ends are stripped;
  • the ends are connected;
  • Heat shrink tubing or electrical tape is applied to the junction of the wires.

The choice of connection method depends on the type of cable, its characteristics, and operating conditions.

When you need to additionally extend the wires in an apartment or house

The need to extend cables occurs in the following cases:

  • if you accidentally cut the wire while working with an angle grinder on the wall;
  • fracture of a carelessly folded conductor in the wiring box;
  • when moving the old device to a significant distance from the outlet;
  • cable extension in water;
  • increasing the length of the LED strip for hidden lighting;
  • damage to the twisted pair;
  • combination of sockets.

Installation must be carried out in compliance with safety regulations and with the electrical wiring disconnected. If you do not turn off the power, there is a risk of electric shock.

How to extend electrical wires

The main extension methods include:

  • connection using a block of Wago terminals;
  • budget pads for connection;
  • use of clamps;
  • twisting (attention - the method is unsafe!);
  • commissure;
  • bolt, nut, washer;
  • crimp cap;
  • sleeve.

To increase the length you will need the following tool:

  • a sharp knife for stripping insulation or a special tool;
  • pliers;
  • screwdriver;
  • insulating material (insulating tape, heat-shrink tubing);
  • wire cutters

Devices must have insulated handles.

If a vein in the wall breaks

If a wire in the wall breaks, you need to decide whether there is enough cable for the connection. If it is enough, you can start the connection in any way. If the length of the conductor is not enough and you cannot get to the broken section, you will have to dismantle part of the wall, release a cable length sufficient for extension, strip the core of insulation and increase the section.

How to grow in water

Extension of conductor in water may be required for submersible pump wiring. Extension must be done with the same cable - with the same characteristics and the same brand. According to the regulations, it is forbidden to increase cables from different companies!

Algorithm of actions:

  • stripping bare wires;
  • installing them in opposite holes of the terminal;
  • installation of heat shrink tube.

Insulating the exposed area with heat-shrink tubing is mandatory, even if the extension is done in the bathroom or outdoors. This will protect the electrical wiring from moisture.

Power supply for powerful electrical appliances

High-power appliances include devices that consume more than 100 watts of electricity per hour. These include washing machines, water heaters, dishwashers, electric kettles.

Extension is made by soldering. Other methods are not acceptable. The soldering area and exposed wires should be insulated with electrical tape.

Step-by-step instruction:

  • a conductor of a similar cross-section and grade is selected;
  • each core is twisted separately;
  • each twist is soldered;
  • insulation is applied;
  • the entire bundle is wrapped with electrical tape;
  • cables connected to the outlet must be tinned.

The conductor cross-section for powerful devices must be at least 4 mm.

Increasing the temperature sensor wire for heated floors

Cables for heated floors can be extended to a length of up to 50 meters. Traditionally, a copper conductor of the PVS brand of the same cross-section is used. Before starting work, you should study the instructions that come with the temperature regulator.

If no additional modes are specified, you can begin building up. It is better to carry out the work using terminal blocks.

To build up electrical wires, you need:

  • remove part of the plastic coating from the conductors;
  • strip the ends;
  • install the wires into the terminal block on opposite sides;
  • put it into a mounting corrugated tube of the appropriate size.

The standard temperature sensor cable length is 3 meters. If necessary, the wire can not only be increased, but also shortened.

Extension of twisted pair cable

Twisted pairs can be made larger by twisting and soldering. The operation should be performed in elderly people. Be sure to insulate the connection points and prevent them from touching.

LED Wire Extension

There are special connectors on sale for extending LED strip conductors. Elongation occurs gradually. Other methods are not applicable.

Important Requirements and Recommendations

Basic tips for extending cables:

  1. If the conductor is replaced in a panel house, there is no need to additionally groove the wall. Electrical wires are placed in pipes, so it is enough to pull them out of the channel and extend them.
  2. The cable needs to be separated and the ends stripped. This should be done at different distances so that the exposed electrical wires of zero and phase are not located opposite each other.
  3. The length of wire for extension must have the same technical characteristics and cross-section as the original cable.
  4. Heat shrink tubing is placed over the exposed areas and heated.
  5. If heat shrink tubing cannot be used, the conductors are individually rewound with insulating tape. This should be done especially for places where solution can get inside the clamp or terminal.
  6. It is advisable to connect the wires by soldering. This is the most reliable way to extend cables.
  7. No twist is used. It is always supplemented with soldering.
  8. Conductors with a cross-section above 4 mm are connected only by soldering. Any other way will bring problems.
  9. The selected electrical wire must be designed for the required power and must not be damaged, cut or broken. It must be electrically and mechanically robust.
  10. Flexible installation conductors must have a reserve length.
  11. It is forbidden to place electrical wires on sharp edges and edges of devices; they will chafe, which will lead to breakage.
  12. Work is carried out with tools with insulated handles.

You must work in compliance with safety regulations. Work should only be carried out when the voltage is switched off. Carrying out an increase in the absence of skills, knowledge and special tools should be entrusted to a professional electrician. Also, a professional must connect conductors from different materials.

Extending electrical wires is a common procedure. It may be required if the cable is damaged, if the device is moved at a remote distance, to increase the length of the diode strip, and in other cases.

The connection can be made using terminal blocks, clamps, soldering, sleeves and connectors (in the case of LED strips). It is necessary to increase the length of the electrical wire, observing all requirements and safety precautions.

If the extension is done incorrectly, the electrical wires may overheat, spark and there is a risk of fire or short circuit.
