Small 11kw heater was used for one spicket at the barn. It has its own 50amp breaker in a subpanel box and runs at 240 volt. Always kept the breaker off until wanted to have hot water. Used to work fine. Now, as soon as I try to turn on the breaker, it trips the main breaker for the subpanel. Any ideas?
