I expect to be buying a new saw and maybe a dust collector in a couple months. Since I have about maxed out my two circuits in the shop already, I will be putting in a new 240v line. Since I have some free time now, I would like to get on it.
Presumably a 20a circuit will be adequate for a contractor saw and a small DC (7 or 8 amps each?) but do they need a neutral? I have a big coil of
12/2 and I would prefer to use it up instead of buying 12/3, but will obviously get what the equipment requires. And what is the outlet, the one with the two blades going the wrong way (6-20R)?
