My Tank Thread
It sounds like two branch circuits were improperly interconnected.
That sounds like our barn. We had a good electrician work on our barn system (for solar, car charger, etc.). He installed arc faults on some of the lines, and we later discovered that turning on an overhead light tripped the arc fault every time.
Turns out the power was leaving the panel on one breaker and returning to it via a different breaker.
Got to love these old wiring situations. :(


low voltage is never good! Maybe you’ll get lucky and it will be on the cities end.
