The main switch of the electricity meter in the residential corridor keeps jumping.

Reasons for frequent tripping of electric meters:

1, because the overload exceeds the rated load, it belongs to overload protection tripping.

2. Because some electrical appliances are grounded, the leakage protection trips.

3. Check for leakage.

4. If the equipment is not leaking, it is a load problem.

Finally, if the above problems don't exist, replace it with a new one with the same capacity to see if the empty one is invalid or allergic.
