A co-worker ran 2 circuits to 2 duplex receps. in a 2-gang box. This was for a new piece of equipment that was ordered. It was supposed to be 120V like the ones we already have. When the equipment came in, it was 240V. We still need 1 of the 120V duplex receps but need 240V for the other. I told him to get a 240V recep. and a 2-pole breaker, re-identify the white wire that was the neutral and he wouldn't have to pull more wires and add another box for the 240V. He ran 12AWG so the wires are good for 20A 240V. He didn't think you could do that but I told him he could. The code, as far as I know only speaks of re-identifying the grounded conductor and not the ungrounded other than not using green, white, or other colors used in grounded or grounding conductors. Was what I told him correct?
