Just bought a house that was built in 1957. Upon going through the panel box, I have found that all three bedrooms and one outlet in the living room (where the TV would most likely go) are all on the same 15 amp circuit (10 oulets in all). Oddly enough, the opposite living room/dining room wall has 4 outlets, with one of them being on its own circuit. What would be the best way to break some of these 10 up? Could I change the breaker to a 20 or higher amp rating, or would that cause any problems with the wire?
