My electrical panel had nothing labeled correctly. The "kitchen" breaker would turn off the master. The "Nook Area" turned off the living room, "Dishwasher" controlled the kitchen outlets, but not the dishwasher, had an unlabeled double 30 amp breaker, and many more. So yesterday I took nail polish removal and wiped the entire panel clean. I shut off everything and then went thru one by one and turned everything back on and relabeled it all.
