If you run a 12-4 to feed multiple circuits for floor machines does the NEC require a 3 pole breaker on this run. I say no but someone said it is code. Are they basing it on NEC 210.4 which I feel does not apply or did the inspector interpit it wrong. This 12-4 feeds 120 volt outlets in 3000 Wiremold mounted on a wall at a medical university.
