60 will work, sort of. Simpler to go straight to 100 amp and then you have the current minimum standard for wiring. Saves time and cash outlay down the road. Not saying that 60 won't work but most new installs usually go right to the hundred from the get-go.Got a big boy compressor.
230 volt, 11.5 cfm, 60 gallon. Will fit my needs just fine.
Also, got power to the garage. 60 amp service. Should be plenty.
