Colin,
That's true as long as the cable is rated for 220 Vac, and you don't want to
add a ground with the neutral. To do it right, I'd want a three wire with
ground cord. Most 120 Vac cords only have three wires. To use a 120 Vac cord on
220, you'd have to use the ground wire for the neutral which most of the time
is a green wire. That is if you intend on using anything on the 120 Vac line.
Plus your using a white wire as a hot. The correct way is have a black and red
wire as hot, white as the neutral, and green to ground.
Best,
Will
