Circuit-breaking receptacles, plugs and connectors ensure complete circuit breaking under full rated loads. Equipment grounding is provided by means of a separate pole that makes contact before and breaks contact after the circuit poles. The delayed action operation sequence is as follows: Insert plug, turn left push in to make electrical contact then turn right to prevent accidental disconnection. To withdraw plug, the reverse procedure is followed, which provides time for extinction of the arc and cooling before the plug can be completely withdrawn
