For comfortable support and use by electricity, in the room the sockets are mounted in the amount of several pieces, but it is necessary to understand that the cable should use the one that was able to conduct the current of the value for which it is designed. Otherwise, if the permissible current exceeds, the wire is possible, as a result of which the wiring will have to be redone in a new way. There are two types of wiring – hidden and open. As a rule, in most rooms they try to perform wiring according to a hidden scheme. The second type, open wiring, is carried out only the inability to carry out hidden.

When installing hidden wiring, you must take into account some conditions. So, the cable must be fitted into a previously lasted channel, especially for laying a cable. Then this channel is sealed with putty or plaster. At the exits, the ends of the conductors should be left long in case the cable breaks occur, it could be pulled out for the left end, rather than carrying out the full dismantling of the canal in the wall.
As a rule, a special socket is installed in the exit sites, and both for switches and for the sockets themselves. Its purpose is to ensure the better fastening of the switch and socket. Such sockets can also be used for laying open wiring, but they will be slightly different in shape and view compared to the hidden type of wiring.
Their fastening in this situation is made in special gaskets made of wood, and not in the wall. Sockets and switches for different types of wiring differ in externally – in an open socket, the insides are hidden by a box. In the hidden – in sight, only the panel is visible. Open -type wiring is relevant for wooden houses, since it is not possible to implement the hidden in them.
