The supply cord has 2 hot wires on opposite legs of the service (red and black), a neutral wire (white), and a ground (green or bare.) It's for a normal 220V 4-wire circuit, like for a modern electric stove or dryer. The white wire is for the timer, clock, motor, electronics, etc that runs on 110v
Got it... the white is the neutral for a 120V circuit. I've dealt mostly with industrial electrical stuff.. wasn't aware of the 4 conductor for home use. Thanks for the info.
