How To Tell If A Circuit Breaker Is Bad
Swap the two breakers in the panel. Turn the MAIN on and flip on the two swapped circuit breakers. If ''T'' holds, and ''B'' trips, then ''B'' is likely faulty. If ''T'' trips, and ''B'' holds, then it is a circuit or load issue. If both breakers trip…. ''B'' could be worn out and can no longer handle normal loads.
