I have a clothes dryer that runs sometimes and other times bypasses the 30a breaker it is on and trips out the main. The dryer comes from a breaker in a feed through outdoor panel. Everything seems tight on both ends, it doesn't seem to pull more than expected with an amp meter on it. Not sure what else to do? The only other thing that looks weird is: the line coming in from the meter goes to the lugs on bottom of panel, then feeds through breakers, then main is bolted on, then it feeds the house. Does this seem right?
