DOMESTIC WIRING SYSTEM

摘要

PURPOSE:To easily cope with an increase in the number of branch circuits on a power supply line. CONSTITUTION:A trunk L0 line is branched into a plurality of truck lines on a distribution board A and each branch circuit L0 is branched in a join box B working as a branching device and freely wired in a free-access follower. Then a plug socket unit CU is fitted to the branched end of each branched trunk line L0 branched in the box B. The plug socket unit CU is integrally constituted of a circuit breaker BR2, a plurality of plug sockets C4 and C4 fed with electricity through the breaker BR2, and modular jack MJ for call and information. Therefore, when it becomes necessary to add a new branch circuit to this system, the circuit can be easily added by adding one plug socket unit and making wiring between the plug socket unit and branching device.
