PURPOSE:To utilize wall face effectively and to keep a good appearance by building a main unit for home automation into a distribution board. CONSTITUTION:A distribution board 5 provided with a main unit is mounted on a predetermined wall face and service wires are led in from a W.H.M. panel and a telephone line protector through a through-hole, made through the wall, and connected, respectively, with a main circuit breaker 2 and a main unit 4 for HA(Home Automation) system. Wiring circuit breakers 3 are then connected with wiring ends, power supply lines for the HA system main unit 4 are connected with a wiring circuit breaker 3 having low interruption frequency thus completing installation and power line connection of the distribution board provided with main unit. Consequently, the service wires are not routed on the outdoor wall face at the time of connecting work. Furthermore, reliability is enhanced because power supply to the main unit can be taken from a desired wiring circuit breaker 3 and the wall face is not occupied by the main unit which is not normally inspected not operated. |
