What should be the wiring in the new apartment?

Hello, dear readers of the my.electricianexp website! Today we would like to tell you about how to conduct an apartment wiring do it yourselfif you became the happy owner of a new building. Installation instructions will be presented in the form of useful tips for choosing components and their independent installation.

Where to begin

First of all, you need to draw up a wiring diagram from the input to the end points - sockets, lamps and light switches in each room. Examples of schemes for one-room, two-room and three-room apartments we have already provided on the site. Finding them is not difficult.

Further, according to the prepared project, you need to calculate and select the appropriate elements of the scheme. When installing wiring in a new building, we recommend that you opt for such components as:

  1. Three-core cable, VVGNG-LS or NYM, cross section 3 * 2.5 mm2 for sockets, 3 * 1.5 mm2 for the lighting line. To connect an electric stove in the kitchen, calculate the cross-section individually for power, however, note that according to SP 256.1325800.2016 p. 10.2, for a cooker, the cross-section must be at least 3 * 6 mm2.
  2. Outlets in the bathroom with degree of protection IP no less than 44.
  3. Illuminated light switches.
  4. A circuit breaker separately for the lighting line, with a rating of 10A and for sockets - 16A. If you have a three-wire network (with grounding), you need to install an RCD of 30 mA for group power networks and for outlets in the bathroom (according to SP 256.1325800.2016 p. 10.2 and PUE Section 7.1.82)
  5. Junction boxes should be in every room. The connection of wires in the boxes is WAGO terminals, PPE caps, sleeves, or other methods other than twists (see clause 2.1.21 of the PUE, Chapter 2.1).
  6. At the input, it is necessary to install an automatic machine that can turn off all the electricity in the apartment during repair work.
  7. It is possible to conduct wiring both openly and in a hidden way (in a strobe or behind a gypsum board). At the same time, note that it is forbidden to ditch walls in prefabricated houses in accordance with Decree of the Government of Moscow of February 8, 2005 N 73-PP “On the Procedure for the Conversion of Premises in Residential Buildings in the City of Moscow”. As well as Government Decision No. 508 (Clauses 11.3 and 11.11 of Appendix No. 1).

These are the basic elements that you must acquire before installation. We draw your attention to the fact that you can not follow our recommendations, for example, conduct electrical wiring in a new building in an open way or choose a machine with a different nominal value. The tips provided above are general, not specific.
