In one of the bedrooms all of the duplex receptacles are 20 amps. Do I need a 20 amp switch?
Also, I have a garage which is about 30 feet from the house and the wire that goes underground is either 10 or 12 gauge. Do I need a 20 amp switch for that? I always thought that if you have 12 gauge wire the receptacles or switches should always be 20.
Also since my garage is all 12 or 10 gauge do the switches in the garage have to be 20 amp? I know NEC makes exception to this rule, but what is the correct thing to use?
