FIELD: electricity.
SUBSTANCE: phase conductors with current-conducting coating applied above insulation and which is electrically connected to terminal of protective earthing in switch board are used. According to this method the single-phase wiring includes switch board, phase conductors and shutoff protection device switching off electrical network when the specified parameters are exceeded with leakage currents.
EFFECT: preventing fire owing to blackout of electric circuit in case of leakages exceeding fire hazardous limit.
