Ok the one thing my garage was lacking is 220v, today I decided to solve this problem.
This will be a 70 amp service panel to run my compressor and TIG welder.
From the main panel I added a 70 amp circuit breaker then ran about 40' of 1" conduit with 3 - 4 guage wires and a 8 guage ground to the subpanel. I plan to install a 60 amp breaker for the welder, 40 amp for the compressor, a 20 & 30 amp breakers for 110.
As for wiring you must keep the neutral separate from ground in the subpanel(code) I plan to run the rest of the wiring tomorrow then get the rough inspection. From there I'll be able to finish the rest.
