I'm building a concrete house and in the garage, I'm hoping to provide for a future when that might be converted to a couple of bedrooms. I'm already putting a small bathroom with shower in it. For electrical, I was thinking about putting a subpanel in there, and then homing one or more circuits from that panel. Is that overkill? Should the garage just be one circuit and forget about the subpanel?
If I do put in a subpanel, what size of wire should I run from the main breakerbox?
If I don't put in a subpanel, will the circuit in the garage just be 12/2 or since I might be operating some drill or saw, should I be using something for a bigger current?
Since we could be putting in a couple of bedrooms, I was thinking the subpanel would be the way to go. It's easier to put it in now, than to deal with it later.
