What should I do if the wires at home are short-circuited? How much is the electrician?

Turn off the main switch at home first, and change which switch you said has problems.

Then turn on the air switch. It's not as serious as you said. It needs to be changed.

All right, nonsense,,,, there's not much money.

Change to a better panel, see which switch panel you belong to, and ask someone to buy a brand-name switch.

Seal the board, don't buy miscellaneous brands,,, remember what I said, buy famous brands, money, and buy them for more than ten yuan each.

Here we are. Once we get it up, 50 yuan will be enough.

At home, the main brake is usually switch one, lighting one, electric water heater one and air conditioner one.

When you say the light is off, it means that the air switch that illuminates this road has jumped.

I've been an electrician for 10 years. To be honest,,, I'm finished.
