Claims

[Scope of utility model registration request]

A grounding chamber having a disconnection section connected to the busbar and a disconnection section connected to the ground wire in a partition from the busbar position, and a grounding device that is inserted into the grounding chamber so that it can be pulled out and connected to each of the above-mentioned disconnection sections upon insertion. and a pull-out mechanism that engages with the grounding device and moves the grounding device in the insertion and withdrawal directions, and a connecting portion between the pull-out mechanism and the operation handle, and is configured to be retractable from the covering position. The shunter engages with the member on the shunter side to prevent the shutter from retreating from the covering position, and is energized under the condition that the circuit breaker for power supply to the bus bar is in the OFF state, and this energization causes the shutter to move from the covering position. A closed power distribution board comprising an interlock magnet that allows an evacuation operation, and a limit switch that locks a closing circuit of a power supply breaker to the bus bar in conjunction with the evacuation operation of the shutter.
