:smile: Hi fellas, most (if not all) of the elevators I have designed, have been wired 3-phase. Just moments ago a contractor approaching me asked me if it was permitted to wire an elevator with 1-phase power. I got right away into the NEC, and found nothing so far that prohibits this. I am aware that elevator motors are big (hence that is why most are 3-phase) What is your opinion on this fellas! Any comments are welcomed!!:smile:
