hi. I've got an attached garage with a couple of plug-ins, an overhead door, and a couple of lights. I want to use the garage as a shop.
I've purchased a forced-air furnace for the garage, and want to run some new electrical for it. The house was built in the 1960s, and I have an existing 100 Amp service. It appears that the garage shares some circuits with part of the basement.
I also want to have 220V available while I'm at it.
My thought is to run 8/3 wire from my existing panel to the garage (approx. 40'), and then run a sub-panel from that. does that sound reasonable? What amperage breaker would I use?
Thanks in advance for any help.
