PURPOSE:To obtain a wiring device which can easily make grounding by providing a grounding electrode connecting terminal in a power supply connecting section and terminals for connecting grounding electrodes cables connected with loads in each load connecting section. CONSTITUTION:The title device is constituted of a basic unit A for connecting prefixed switches and loads and additional unit B for connecting additionally installed switches and loads. The unit A is provided with a connecting section 2c for connecting power supply cables from a distribution board, a plurality of connecting sections 2a and 2b for connecting the loads which are turned on/off through the switches, and an internal circuit which is composed of conductive plates and supplies electric power to the loads. At the same time, the unit A is provided with a connecting section 2d for connecting a plurality of feeder lines so that the unit A can supply electric power to the additional unit B. The unit B is constituted to connect a plurality of switches and loads and terminals for grounding electrodes are provided in the load connecting sections of the units A and B. Therefore, wiring work for grounding can be easily carried out. |
