Isolation switch on the master terminal, ensure the formation of a significant portion of the fracture and charged Huizhou isolation isolation switch lines and equipment maintenance, as a result of the isolation switch is not extinguishing devices and low breaking capacity Foshan isolation switch, so the operation isolation switch, you must Switching to comply with the order of operations, gives electrical isolation switch, the first bus side isolation switch is closed, followed by closing the line side of the isolation switch, and finally close the circuit breaker, power is contrary to the above. Does not apply where there is isolation switch: ⑴ conductive or chemical action of gases, vapors place; ⑵ of fire or explosion hazard (if gas pit); ⑶ a lot of dust gathering place; ⑷ strong vibration and or impacts; ⑸ particularly damp places and tropical regions.
