Replacing the old switch to the new, and what to do if the wires are too short

Carrying out repairs in the house, often we are not only sticking wallpaper and fixed plinth, but also changing the switched outlets. And sometimes there is a situation when an urgent need to replace the dilapidated switch. In this article, I'll just tell you how to change the switch, as well as how to get out of a situation where the "stock" wires in a box is almost gone.

the necessary equipment

In order to successfully carry out this work, we need:

Phillips screwdriver or flat blade.

Hidden switch or outdoor performance (depends on which switch you stood up to it).

Stationery knife for stripping insulation.

Pliers and terminals (if necessary to increase the wire in the box).

So, the necessary equipment is prepared, you can begin to work.

perform replacement

Safety first, so the first thing we disconnect the power supply of the machine room, if none, then disable the total feed machine.

After that, remove the decorative cover.

Then, using the meter or indicator to verify the absence of voltage, and only then take a screwdriver and disconnect them from the old switch.

Next dismantle the switch itself, and have an empty space set a new one.

Everything is now process the new switch connection is performed strictly in the reverse order, namely:

For a fixed switch we connect the leads, then set the trim in place, turn on the machine and check the power supply switch.

This algorithm is fair to say so, ideally, when the supply of the power cable is sufficient and It has copper wiring, but but what to do if the stock wire is extremely small, and even aluminum conductor cable. Next, consider the example of the already double-breaker installed a hidden way.

Building up wires

Important. Capacity wires - is an extreme measure that should be avoided in every way. It is best to lay a new cable from the junction box to the switch.

So, you need to change the failed switch and there is no margin of wires. In this case they can be extended, for example, via the terminals.

To do this, we clean the wires so that they can be inserted into the tube, then take three separate wires and fasten them on the other side of the terminal block. And already then fasten the same wire to our switch.

Then we set the switch Escutcheon and fix it by means of fixing screws, set forth key. And yet, the installation process is complete.

Thus it is possible to install a new switch, even with very small reserve supply cable. Thanks for attention.
