12/2 vs 14/2 romex
I have an old house. It was built in 1952. My circuit panel has 6 circuit breakers. Two of them are connected to each other. I have a sub panel mounted outside to handle more circuits because when I put in a pool a few years ago the inspector made the electrician do than. I want to tap into a wall circuit in my bedroom and run a line outside so I will have an outside plug. It appears my breakers are 15 amp (except those going to the pool). I have some 12/2 romex. Can I use 12 ga. wire on a 15 amp circuit without any trouble?
