The electric air switch on the first floor of the corridor light has been on for more than an hour. What is the significance of adjusting a transfer switch?
The main reason is that the air switch is overloaded and the line insulation is low, which leads to tripping.
The air switch cannot be turned off normally:
1. Check whether the air switch is damaged.
2, check the air switch wiring is correct. Incorrect and rewired.
3. Check the line insulation on the load side of the air switch. If it is short-circuit grounding, it can be closed normally after troubleshooting.
If it trips as soon as the power is sent, it means that the line is short-circuited to ground.
