The weather is rainy and the walls are wet; There is nothing wrong with the circuits above the third floor. The leakage switches on the first and second floors do not trip. Total leakage switch 100 A, total tripping? I don't know whether you want to find out the reason or the solution to the problem.

There are two possible reasons:

1. The line embedded in the wall is damaged, but it does not affect your floor use.

2. The rated current of the main brake is not enough. It's hard to be sure without your three missed models. You can take down the missing report at the gate and try to change it to a bigger one. If you still jump, check the route along the road. If you don't jump, change the leakage protection at the gate to a bigger one.

To solve this problem thoroughly, it is suggested to check the line between the main entrance and other floors or re-take the casing, and pay attention to the binding of nodes.
