PURPOSE:To reduce the number of wiring by opening/closing a power source circuit through a wireless remote control relay which is turned ON/OFF through a wireless remote control switch thereby preventing concentration of feeder wires for respective lighting loads to a distribution board. CONSTITUTION:Circuit breakers 9-9a are provided for lighting fixtures 7-7a-7b..., 8-8a-8b.... Main lines 10 for lighting are led out from a distribution board 3 and connected with the input terminals of the circuit breakers 9-9a, and the output terminal of the circuit breaker is connected with lighting fixtures 11 for corresponding group. The lighting fixtures 7a, 7b, 8a, 8b are connected with source wires through series connection of a wireless remote control relay 11, and turned ON/OFF through the remote control relay 11. Since the circuit breaker is arranged closely to the lighting fixture, fixing work of distribution board is not required. |
