My forthcoming move to the new shop is underway. Three double drops
have been installed in the ceiling of the two-bay garage, running
off a dedicated 20 amp service. I thought about adding a 220

This subject has been beaten to death, but suffice to say,
it is in your best interest to operate your power tools at the highest
voltage
available which for most shops will be 240V/1PH/60 HZ.
