Sub Panel to Attached Garage
I want to install a sub panel in my attached garage with a 60 amp breaker.
The wall between house and the main panel is approximately 50 feet. I could put the subpanel in the wall that separates the garage from the house, but I would rather not poke any wholes through the firewall, plus getting all the receptacle electric lines would require me to drill holes through the top plates between, walls and it seems really labor intensive, plus the panel ends up in a not so convenient location. I think I could get away with 6 AWG wire for this run.
The other idea I have is, is run the wire in the basement along the floor joists (in conduit obviously), behind the garage, exit the house, bury the conduit in the ground for about five feet and go back into the garage. The location for putting the panel there is really convenient, the biggest one being the walls on that side of the garage arenít finished so fishing wires all over the place would be quiet easy. I donít need to put any receptacles on the firewall side of the house because there are enough receptacles that came with the house there. The only problem I can think of with this is the distance for this run is about 100 feet and it would require 3 AWG wire, which is a lot more expensive that 6 AWG wire, plus itís twice the distance.
Does anyone have any better ideas? I really would rather not cut into the firewall on the house and poke a lot of holes in there for the sub panel, probably by the time Iím finished Iím probably tearing out a whole finished wall.
