In the houses that were built many years ago, the wiring is not designed for the number of electrical appliances, which is used to date in the apartment.
Consequently, the capacity of the posting set 20 years ago, much lower than the power that consume air conditioners, electrochetics and computers. Before starting work, on the replacement of wiring, it is necessary to determine with the type of cable. And in this case, the best will be a copper stranded cable that is durable, has excellent bandwidth and has a long service life.
Steps to replace wiring:
- compilation of an apartment electrical wiring plan, which should be noted all sockets, switches, wires and their location relative to the floor and ceiling;
- By plan, calculate the number of required cable, sockets and switches, as well as place their location on the wall. For each switch and socket, you must take 1 installation box. For sockets, it is better to use a 2.5 square cable, and for the lighting line 1.5 square;
- Deadly de-energized an apartment with a shield, and dismantle the old wiring. If the old wiring is laid in the channels, then it is dismantled and the installation is performed at the same time, by putting the end of the old wiring, the end of the new and pull the second end of the old wiring. If the plan of the new wiring does not coincide with the plan of the existing one, then you have to pierce the shoes. In the event that the old wiring is wengged into the wall, it is necessary to dismantle it, or leave it in the wall, and the new to lay in another place;
- With the help of the perforator and the grogging, the cable is made primarily from the counter to the distribution boxes. The cable is placed in the corrugation, stacked in finished shoes, and is fixed by alabaster every 1.5 meters. From junction boxes, laying a cable to switches, lighting devices and sockets. It must be remembered that the connection of the cable should be done using a special clermin. Such a connection will be better and safe. When all work in junction boxes are completed - you can move to the apartment power supply;
- The last stage is the connection of the apartment layout to the meter. The counter is also better to replace, with automata installed on it. Next, connect the apartment wiring to the machine. If you turn on the machine, it is not knocked out - it means everything is connected correctly. After that, all sockets and switches are checked for performance.
