I live in Arizona, I have just built a detached 2 car garage, since the electric supply is much closer to the garage than my house I propose to drop the overhead supply down onto the garage or rather the electrical company will. Then i intend to feed a breaker box in the garage and run a supply underground up to the house.
I have already dug the trench and got the 2" PVC conduit and cable.
I worked as an electrician in England and am a little unsure about American wiring, I am not sure how many cables I need to pull through the conduit, the existing electrical company overhead line has 2, I have been told that I need to run three - what are the three wires for, I can see live and neutral would equal two, is there two hots and if so why?
thanks
