The idea of replacing the wiring draws a picture with broken walls and mountains of garbage throughout the apartment. But how else, when in panel houses, all the electrician is deadly in the walls and for its replacement, it is necessary to stroke the channels in the walls.
Before unpacking the construction tool to extract the old wiring, you need to pay attention to the floors in the apartment. In panel houses of earlier buildings, they are made of wood massif, which means under the boards we walk, full of space so that electric wires would lie there. Laying wires under the floor is very simple. There is always a technological gap into which the wiring will always pass between the floor boards and the walls. To perform installation, it is necessary to remove the skirting board, lay the wiring under the boards and close the gaps again with the plinth.
The use of this method of laying wires will relieve the need for stroke of channels along the walls of the rooms. Strop the walls only to connect the switch and sockets. Due to the fact that there will be practically no channels in the wall, finishing materials for lighting the channels will be needed in fewer. And the speed of mounting electricians in this method itself is significantly accelerated.
At the time of power outage, I can only advise the installation of diesel generators, they have not yet come up with another source.
