Wiring in New Addition?
I am adding an addition to the back of my house with a half bath. I plan to have a couple of receptacles, overhead lights, and fan in the room. On the outside I plan to have 2 lights on each side of the door. Then in the bath i plan to have a receptacle, light and exhaust fan.
By code, how many circuits does this have to be on? Can I get away with one circuit? What size breaker?
I think I have to use 12/2 romex for the bath? If so and it is all on one circuit, does all the other wiring have to be 12/2?
