We have a 100-year-old house in New England and, finally, stuff is breaking down. In several rooms, lights blink on and off without warning. Breakers trip constantly and many electrical sockets are dead. I think I'm in over my head. What's an estimate of what it will run us?
Now that I'm up to my neck in a home addition, I need some information about swapping out old electrical receptacles for ground-fault circuit interrupters. CGFI units are almost always labeled, but should I use a multimeter to confirm the circuit map in the breaker?
