Sorry to waste nandwidth but I have been unable to find an answer to this. I am hooking up some 230V woodworking machines and have 2 questions:
1) The NEC implies that each motor over 1HP needs its own protected circuit - Is that true for a 'one user shop' i.e. can I have my frequently used 2HP dust collector and my infrequently used 2hp jointer on the same 220v circuit?
2) When wiring the 220v only machines - The machines have 3 conductor plugs - I pulled 10/3 wire - what do I do with the unused conductor - do I just tie it off at the machine, connect it at the box, not connect it ???
