:-? i have a 200amp service at my house (quad level home, w/ attached garage), which my panel is in my basement. i want to put a sub panel in my garage, but since i only got two circuits going out there, one for the lighting and the other for a GFI. I'm thinking of putting in a furnace, a compressor, a whole lot of florecent lights, ect.....what size pipe and wire should i run, and what size circuit breaker should i use?
