This is old subject, but still can't figure out why on a new oven ckt, the manufacturer says you can use a 3 or 4 wire ckt. The oven controls must be 120v, which would mean you'd be tying the neutral to the ground at the oven (cause they are 4 wire) and the ground would then be part of the current carrying path back to the panel on a 3 wire ckt. Is this code for new ovens?
