Extend an electric wire in a wall: here are some effective techniques

To extend an electric wire in a wall, different possibilities are available.

Use a domino

The domino technique is the most used when it comes to lengthening an electric wire in a wall. To do this, you must first dismantle the grip and identify the electric wire to be extended. When the wire is identified, it starts with carefully stripping it. Then, bring the existing threads to the domino so that they coincide with the extension wires. Here, it is therefore necessary to respect the colors of the electric wires. Once the two wires have been connected, everything you need to do is screw them to correctly correct.

Good to know: To choose the domino to be used to extend an electric wire in a wall, take into consideration the power, the diameter of the wires to be connected and their number.

Opt for a Wago connector

The Wago or Quick Colling connector is also a good idea to extend an electric wire in a wall. This domino without screws is fixed as a classic domino. The only difference is that it is not necessary to use a screwdriver to connect the wires. In fact, the tightening of the electric wires is made thanks to a manual lever or a small spring. These opening and closing systems directly imprison the threads.

Weld

You can also extend an electric wire without using the Domino or Wago connector. In some cases, a simple welding made with care could be sufficient.

To determine if this solution is feasible, before performing the extension, the original conditions of the threads and their seniority must be controlled. It is also necessary to take into account the desired connection distance and the choice of installation. In addition, to carry out the work, having the right tools and some technical concepts is essential.

Security measures to be taken

Extending an electric wire in a wall for your external layout or other reasons is quite common and seems extremely simple in theory. However, that’s not the case! All management must be carried out with care and attention to avoid problems and damage.

Before lengthening an electric wire in a wall, it begins by ensuring its safety by cutting the electricity on the electrical panel. This is very important to avoid the risk of electrocution, overtention and short circuit.

In addition, equip you with all the materials and tools necessary to perform the operations at best. In general, for this type of work, it is necessary to have in its possession of the screwdrivers of different shapes and sizes, electrical cables, insulating material, welding materials (welding paste, tin, electrical welding, etc.) and of course domino or wago.

Finally, do not forget that any changes, at the level of the electrical circuit, must impractically respect the NF C 15-100 standard. This standard guarantees sufficient and safe electrical installation to promise the comfort and safety of the occupants of the accommodation.

In any case, if you are not used to doing this type of work, the best option would be to contact an expert in the sector. For example, you can call an electrician.
