My main panel has been upgraded to 100 amps. I would like to add a subpanel in the garage which would supply:
- 20 amp Mig welder running on 120 volts, but later upgrade to a larger Mig welder as i am experienced at welding.
- Large jointer
- Medium sized table saw, which is 120 volts and 12 amps
- 4.5 hp portable shop vac
- A sander
- Branch circuits for good lighting, and 5 receptacles.
The main run from the 100 amp panel is 37 feet exactly, so what would be the ideal gauge and type of wire to use for feeding the sub-panel?
Is it a good idea to run the wire in metal conduit the whole span, since the feed goes though the basement ceiling and though a concrete wall in the most direct straight-line to the garage?.
I would like to do the job myself as I have seen the sloppy job the so called electrician did with the main panel, which passed hydro's inspection! I have taken and passed an electrical college course at my local college, I have an eye for detail and am a perfectionist.
