Hello. At the end of August, I noticed a strange phenomenon in my apartment. When in the socket located farthest from the fuse box (fuse, two phases) a device with a high power consumption, e.g. a computer, is connected, the box sounds as if a short circuit, but nothing happens, it does not knock out. However, that's why I don't use this socket for my computer, I don't know what would happen if it lasted for a few minutes or hours. However, when it comes to sockets located closer to the fuses, they do not cause a scratching effect in the fuses, but it is audible in the sockets themselves. I also did a test and connected the phone with the charger itself, to exclude the influence of another device, I disconnected everything else along with the refrigerator, and after a few seconds the shooting in the telephone socket started anyway. There were already 2 electricians, measurements ok, fuse box cleaned, sockets checked, they see no problem. I noticed one regularity, namely it happens most often on a day like today, warm and sunny, when it is cooler or it is night, it is rather calm. What's up?
