When a breaker is tripped, it's always the main breaker, not the

This is troublesome because I then have to turn off all individual
breakers with the main breaker on and flip each breaker to see which one
causes the trouble.


What is the rating of the main breaker? What is the load? if the main
is 100 and you have a bunch of 20A breakers pulling 15A the group would
trip the main.

You should do some analysis to see if you are overloading the panel. If
you added Central AC, larger water heater,dryer, electric range, they
may not be a problem individually but together, too much for the main.
