Naide property

There are many reasons for leakage switch tripping, and the main reasons are as follows.

The switch is overloaded and the rated current selection of the switch does not match.

Grounding the live wire on the load side of the switch and grounding the zero wire on the load side of the leakage switch will also lead to tripping.

The switch is damaged or the electrical appliance is short-circuited, and whether the zero line of the load side is mixed with the zero line of other circuits. So give the following suggestions.

Unplug all loads on the load side of the switch, and then observe whether the switch trips.

If the line trips at work, it may be the electrical appliance or the switch itself.

According to your description, it is very likely that the lighting control line is short-circuited to the ground, which leads to the trip.

Because the short-circuit grounding resistance is relatively large, the short-circuit current cannot trip the switch at once. If the live and neutral wires are short-circuited, the switch will act immediately.

It is recommended to check whether the switch is damaged and whether the switch control line is short-circuited to ground.
