I moved into a new (old) house a year ago. It has an addition on it (that is also old). Last night part of the electric in the bathroom in the addition when out. My husband flipped all the circuit breakers, and none of them resolved the issue. We started searching to see if there is a separate panel for the addition. We couldn’t find anything. He was about to call an electrician when a little voice in my head said:
“If there is a GFCI outlet, and it trips, everything past the GFCI outlet is dead.”
I remember reading that on this board. Knowing that the bathroom has a GFCI outlet near the sink, I pushed the button and VOILA! The lights come back on.
Thank you, board, for saving me the cost of an electrician to come and push the GFCI button. I guarantee, I will never forget that lesson!
