The baths are present high temperature and humidity, so wiring to special requirements. The pad wiring in the sauna should be performed according to GOST P 50571.12-96.
General requirements
Scheme bath includes electric power supply panel, wiring, switches, sockets and lamps.
In panel mounted breakers to protect against short circuits and RCD protection against leakage currents. Powerful consumers (electric steam boiler, washing machine) must be connected to the individual machines. In their absence, it suffices to establish two automatic switch - on zero and phase conductors. Tripping current RCD - 30 mA.
All rooms except the steam room, you can use three-core copper wire VVGng. The third core is used to ground electrical appliances and fixtures. Wiring in buildings of stone can be laid concealed in the wood - in plastic boxes.
Boxes in which the wires are laid with combustible insulation, insulated from the wooden walls of asbestos gaskets. Gaskets must protrude outward from the boxes on 10 mm.
Wiring paving walls vertically and horizontally. All compounds operate in the junction box. The minimum distance from baseboards, ceilings - 20 cm, from the window and door openings - 10 cm. Fixtures in the washing must be airtight.
Switches and sockets installed outside.
Wire installation in the steam room
GOST sets steam division into 4 zones, as indicated below:
- only the electric heater can be installed in the first zone.
- a second electrical zone absent requirements.
- The maximum operating temperature of electrical equipment in the third zone should be greater than 125 degrees, the wiring - 170 degrees.
- Only electric heater control devices (temperature limiters, thermostats) can be located in the fourth zone.
Wiring must be calculated on the temperature of 170 degrees.
All electrical equipment must have a level of protection above and 1R24.
Installed in the steam room switches and sockets is prohibited. They are placed in the vestibule or rest room. For three-core wire is used, heat-resistant wires, PRKS, RKGM, ADCP, PRKV (temperature limit of 180 degrees), PMKT, JLFLEX HEFD 205 (200 degrees).
Paving the wiring as described in the previous section. Thus the use of metal tubes is unacceptable. Fixtures must be sealed with a porcelain housing base and the glass bubble. Plastic products should not be used.
