I am running a new 220 line for a new piece of equipment. The wire is 12-3, the breaker is a 20 amp and the plug is a Hubbell 4560 twist lock.
My question, the breaker has 2 hots, red goes on 1 black goes on the other the ground goes to grounding bar. On the plug red goes to one side black goes to the other and ground goes to green ground screw. WHERE DOES THE WHITE NEUTRAL WIRE GO? Does this just get cut off?
