配電盤の接地装置。 One terminal of the circuit breaker is connected to the main circuit disconnecting contact, the other terminal is connected to a shorting plate, and a draw-out type circuit breaker equipped with a grounding contact is connected to this shorting plate via a grounding conductor. When the switch is pulled into the specified position, the main circuit disconnection contact is connected to the main circuit of the switchboard, the grounding contact is connected to the grounding contact, and the circuit breaker is turned on, thereby disconnecting the main circuit of the switchboard. In the grounding device of the switchboard to be grounded, a detection conductor connected to the main circuit disconnection contact is drawn out from the upper front of the drawer-type circuit breaker, and a liquid crystal display that is activated by sensing the electric field is placed near the detection conductor. A grounding device for a power distribution board, which is characterized by being equipped with a grounding device.
