The electrician was beaten by the property security guard.

Hehe, you were fooled by the property. I am the property maintenance. The root cause of your problem is that the short circuit of the grounding plug (socket panel) at home causes arc and high temperature fire, and the responsibility lies in property maintenance. First, it is illegal to put out the fire by force. We're going to cut off all the power and cut off the power of the air switch on the wall where you enter. Second, push the main power supply up (after disconnecting the disconnector, the main power supply can be pushed up, indicating that the circuit will not be short-circuited), and then push the small switches at the back in turn, which is a phenomenon. There may be one or more groups of line switches that can't be pushed up, which is the problem line, and then check the line. This does not need to be searched by electricity, but can be found by multimeter. Third, the failure of home appliances will generally produce high temperature, which will cause the electrical appliances to have a pungent smell. Experienced electricians can find the problem according to the smell. Now let's talk about this "electrician" mistake. Forced power transmission will damage the electrical appliances in the owner's home. As we all know, the circuit installation of residential buildings in Shanghai is clearly defined, which ones need to be installed separately and which ones need to be grounded. We just need our electrician to know some basic information from the owner. I also have some experience as an electrician, but I haven't heard that electricity can be sent by force at home. This electrician is awesome. Go to the property, take pictures of the scene at home, and you can find an expert to identify it. Property will fool people, but all the disguises will be exposed in front of the facts. Hehe, I wish you success. You can ask me if you don't know. I hope my answer can help you. ...
