This is probably going to sound awful easy, but I don’t do this sort of thing and I have no one to ask. I put a new motor on my table saw, wired for 220. The wiring diagram says to connect one lead from the motor box to the “ungrounded” connection on the plug, the other to the “line connection”. If you stand looking at a 220 outlet (not the plug) on the wall with the ground hole at the bottom (not one of the big outlets, just the size of a 110 but with horizontal plug holes) which one is the “ungrounded” and which is the “line”? Thanks in advance.

On a 240v two-wire connection it doesn't make any difference.
