The newly renovated house kitchen leaked electricity and jumped the main gate, please ask what the p

First of all, the leakage of electricity in the kitchen of the newly renovated house is an abnormal phenomenon, and the questioner should first check what causes the leakage in the kitchen? Is it because the insulation layer is a little damaged during the construction of the line? Or is the wire pipe, or the electric kitchen socket electricity where there is water seeping in, or other reasons, in short, jumping the main gate is not a very big problem, but the kitchen leakage, this is more dangerous, and it leaks on the main switch, generally speaking, it is a plumber, when installing the kitchen switch, he used a single switch, so its zero line is connected to the main switch, so that the leakage, slight leakage, a separate live wire switch will not jump, Then it jumps directly to the double skin switch of the main switch.

Cutting corners, not standardizing the construction, anyway, just didn't do a good job. Separate each line, measure the insulation resistance of each line independently, find out the leakage of the line and redo it, and make a flying wire to skip this section if there is difficulty. I threw off the leaky line.

I also encountered the same problem, more than a year, no solution, the decorator said that it had never happened to such a thing, I said that it was my bad luck.

Is it a high-power electrical appliance used at the same time?
