Replace 1 20a arc fault Replace 1 20 a duel function Today we found two faulty breaker’s. One breaker was controlling the dining room circuit, which had a mini fridge as well as an espresso machine. Once we replace the breaker, everything was holding fine. Second location was for the dishwasher. Soon as I plugged in anything with the larger load in the dishwasher it would trip immediately. However, the dishwasher itself was needing to run about a half a psycho before with trip off. I replace that breaker is well and everything is now holding properly.
