Wiring the shop and from posts i've read that many folks have commented that one thing they should have done differently was to run more outlets...both 110 and 220.
So i'm going to run a good many around the shop and i was planning on running 12/2 but just want to make sure there's no reason i shouldn't run 10/2. The recepticles will only be 20A and i don't really plan on plugging the table saw, planer (it's 3 phase), or dusk collector into it. I probably will plug the 8" jointer into it but i really don't have that many other 220 items. So it seems to me 12/2 is fine but it's easier to ask now in case i'm missing something.
note -- for the table saw i'm planning on having power come up through the floor in the middle of the shop; the dust collector will be in another room; both of those will be dedicated circuits.
