My circuit board has two main breakers, each has 4 branch circuits. Recently one of the main breakers went ( not any of the branch), so I reset it. seemed OK for a while but went again this evening. I suspected the circuit in the kitchen, and turning that on seems to trip the main breaker, however now it seems the other branches are also causing the main breaker to trip ( ie the kitchen circuit is off).
Do the breakers happen to die?
