Simple technology for building wires and cables

There are several basic situations when you need to perform the build-up of electrical wiring. Most often the need arises if the aluminum conductor in the socket breaks, but there are cases when it is necessary to extend the cable from the electrical appliance to connect the power. Next we will consider all the most common cases and tell readers of the site Sam Electric how to increase the wire in the socket, under water and to connect the powerful household appliances.

The main ways to build

First let's look at how you can extend the wire or an electrical cable at home. If the cores of both spliced ​​conductors are made of the same metal( copper or aluminum), the following extension methods can be used:

  1. With the WAGO terminal blocks. The most convenient option is not only building, but also connecting electrical wires. It is recommended to use even in that situation, if conductors of conductors from various metals. Wago terminal blocks
  2. Low-cost connection blocks, allowing to extend the wiring. Connector Shoe
  3. Twisting of cores. The grandfather's way, which is one of the most unsafe, but at the same time popular even from experienced electricians. To increase wiring with twisting, it is necessary that the broken end be at least 30 mm( for reliable splicing).For information on how to correctly twist the wires, read the corresponding article. Coiling with insulation
  4. Soldering. Another option of extending the wiring is the use of soldering wires. If you know how to use a welding machine, this method will make it possible to increase the conductor even of a large section( 4-6 mm square).Soldering electrical wiring
  5. Cases. The extension of the broken section of the cable by the sleeves, in fact, as well as the nut clamp, can be used for the installation of electricians, but it is still not an expedient method. The walnut takes up a lot of space and obviously does not fit in the jar, and it takes more time to pressurize the sleeves.

We draw your attention to the fact that it is possible to lengthen aluminum conductors with copper ones only if a special terminal is used for splicing. All other options that allow you to build a line are strictly prohibited!

Here we have examined what methods exist for building electrical conductors at home. Next to your attention will be given the typical cases when you need to lengthen the wiring yourself, and now we recommend viewing the visual video instruction:

So, now we proceed as follows:a specific case that can occur in everyday life, and immediately provide instructions on how to properly build up the wire and cable.

  • The vein in the wall broke. If you decide to move the outlet or switch to another place and you have broken off one of the wires during electrical work, then you need to act according to the situation that has arisen. The length of the lead-in wire is sufficient for building up - install the terminal block and extend the short conductor with the same cross-section and material of manufacture. If, however, there is a very short conductor in the shtrobe - break the wall section, free a sufficient length of power cable for building up, strip the vein to metallic color and extend the section. This technology is also suitable in case you need to increase the wiring in the junction box or on the ceiling to connect a chandelier or any other luminaire( for example, a wall-sconce).Wiring extension in the wall
  • It is necessary to increase the cable in water. This situation arises if it is required to extend the supply line for the submersible downhole pump. In this case, experts advise carrying out the extension of the site with a conductor of the same brand. To extend the cables of different brands is prohibited according to the regulations. All you need is to connect the spliced ​​residues through the terminal strip, then insulate the extension with a shrink tube, as shown in the photo below. It is recommended to insulate the bare area with a shrink tube, even if there is a need to increase the wire in the bathroom or on the street to protect the wiring from increased humidity. Site isolation Use of heat shrink tubing
  • It is necessary to extend the cable to power a powerful electrical appliance in the apartment. Another of the situations that should be taken seriously is the extension of the lead-in wire for the connection of powerful household appliances. For example, if you decide to connect an oven, air conditioner or an electric stove, and the copper conductor has broken off at the input( its cross-section must be at least 4 mm2), then the terminal block will not work, becausecurrent loads from the appliance will be significant. In this situation, it is recommended to build up the wire with soldering, then carefully insulate the area with electrical tape. Intrusion of lead-in electrical wiring in the wall
  • It is necessary to increase the cable( or rather the cord) for connecting household appliances of low power. If you have a not very brilliant idea - to make lengthening the cord from a washing machine, hood, music center or microwave oven, it is strictly forbidden. First, you can mistakenly build up the wires incorrectly during the build-up and connect the lead-in phase conductor to the ground, which can result in dire consequences. Secondly, in this case it is much more reasonable to make an electric extension cord with your own hands and hide it along the baseboard, which will be safer and faster than lengthening the whole cable.

  • The length of the wire of the thermal sensor system of the warm floor is not enough to connect to the thermostat. In this case, it is recommended that you first read the instructions supplied with the temperature controller and if no restrictions are specified, you can safely extend the temperature controller cable by using the same terminal blocks.
  • It is necessary to increase the LED strip wire for concealed ceiling lighting. No difficulties in this situation should arise. There are special connectors, which allow you to perform a consistent extension of the LED lamp. The main thing is to take into account the requirements that we provided when we considered the tips for connecting RGB tape with our own hands. Connectors for connecting ribbon segments
  • The twisted pair cable is damaged. In this case, the site can be built up with a new twisted pair by twisting or soldering. The main thing - carefully isolate each place of extension, so that the bare veins do not touch each other. Augmentation of twisted pair

That's all I wanted to tell you about how to increase the wire in the socket, under water and other non-standard situations. We hope that now the extension of electrical cables and wires will not cause you difficulties when installing electrical wiring yourself!
