I live in a apartment, it has a 100 amp main breaker. It trips usually everyday at 6 pm and sometimes a couple of times after the first.
The individual breakers don't.
The main breaker gets hot to touch.
The maintenance man has an amp meter. Checks to see it it getting overloaded. But the amps never go over 70. We turn everything on as when it tripped. Now they to the point they say they going to change the breaker box.
This is getting to be a pain in you know where. I thought there could be a short somewhere, but seems it would trip the individual breaker first. Those breakers are not even hot. Mind boggle.
