For general power transmission operation: firstly panel disconnect switch, and then close the circuit breaker or panel disconnect switch.
When the panel disconnect switch is powered off: first disconnect the circuit breaker or load switch, then disconnect the isolating switch.
When choosing, it is no different from other electrical equipment. It must be rated voltage, rated current, dynamic steady current, and thermal stable current.
The function of the panel disconnect switch is to disconnect the circuit without load current. The device to be repaired has obvious disconnection point from the power source to ensure the safety of the maintenance personnel. The panel disconnect switch has no special arc extinguishing device and cannot cut off the load current and short circuit current. Therefore, the panel disconnect switch must be operated only when the circuit is disconnected from the circuit breaker.
