Can I use 10 3 wire for a hot water heater?
A water heater requires a black wire, white wire, and a ground wire. With a 10-2 ground shielded cable, white and black wires act as hot conductors. The ground wire will run to the neutral plug. If you have a 10-3 ground shielded cable with an extra conductor, the black and red wires are the hot conductors.
