Hi fellas,
Well according to 408.3(E) the high leg shall be marked or distinguished from the other phases when using a 120/240V, 3ph, 4-wire system. NEC 110.15 reads in part that "Such identification shall be placed at each point on the system where a connection is made if the grounded conductor is also present." Besides putting a marking/label in the panel and feeder, shall I identify each circuit breaker position (b-phase) with an orange marking or this identification will be at the point of connection whan I use the B-phase (and ground)?

Any input is welcomed, thanks ahead guys (and/or girls)

:smile:
