Mostly to, first, sometimes warm it up during winter weather when I need to work on something, and second, I want 220V there for testing various military surplus equipment that I sell. I have a 220V generator, but it is a pain to wheel it to the garage. I feel that the better solution is to install a proper 220V circuit.
I have some space lift in my panel.
Please criticize my plan:
1. Install a double 20A breaker for 220V. 2. Use 10 gauge wires 3. Use rigid conduit (EMT). 4. Install a 20A double plug 220V receptacle.
Would this be sensible?
