  • Roulette;
  • pliers;
  • side cutters;
  • screwdriver;
  • punch;
  • Uglovoyshlifmashiny (Bulgarian) or wall chaser with household cleaner;

  • Cable knife.
IMPORTANT!!! Wiring in a private house with his own hands starts with defining the scope of work:
  • Quantity and power of home appliances;
  • The number of sockets, switches;
  • installation household appliances Places;
  • Neobhodimogokolichestvo cable or wire;
  • The quantities of circuit breakers with the calculation of power consumption;
  • Positions where the electrical panel.

Installation of the control cabinet (panel) ↑

Any electrical installation begins with the installation of electrical distribution panel. There is 2 types of these devices:

  1. Vnutrenniyraspredelitelny plate (mounted in a cut by using a grinder or the opening wall chaser appropriate size);

  • 10A SPST AB illumination (dependingthe number of rooms, given the bathroom, toilet and other facilities). Since the lighting network potreblyaetmalenky current, efficient use of the machine 1-2 to connect the entire apartment or house;
  • Single-pole 25A AB - a rate of one switch per room. They serve to protect the wiring, appliances and equipment from short-circuits.
  • If you have smontirovanboyler, and it requires an additional two-pole AB 25A;
  • To connect the electric needs one- or three-pole AB 40A, depending on its type.

As a result, you need poluchitsyavot such or similar electrical panel

To start stretch cable (wire) in the corrugations, and then using special clips fasten it to the walls of a wooden house or apartment.

As a result, one end of the wiring in the ripple will be at the points where you want to connect, and the second - in the place of installation of the electric panel.
