Thank you very much for the help. I tell you that the installation of my house is new, and from the beginning this happened. The odd thing is that it doesn't happen all the time but very occasionally. It may be because many times there is low tension where I live? So you recommend changing the thermal for a similar one? It is one of 20th Siemens. I was about to put one of 25. IN my opinion it is because of the refrigerator that I have that is more than 10 years old and maybe when it turns on it consumes a lot ... But the strange thing is that it does not always happen
thanks in the thermal that jumps I only have the plugs of the refrigerator, tv, microwave, the varropas and something else that can be plugged in sporadically. the rest of the appliances (such as air conditioners) are in another thermals. Can it be that the refrigerator being 10 years old when you turn on consumes a lot? But what seems odd to me is that if so, you should skip the therma every time you turn it on and it is not what happens ... it jumps very occasionally ...
Once a long time ago I had a similar problem. Even the thermal of a sector jumped only with the bell connected. The problem was that the ants had nested in the pipes and were responsible for driving between them simulating a ground leak. Many times the socket boxes are filled with grit causing this problem and disconnecting the differential.
