Ground the bare conductor to the heater cap off the white and all you have is black and red left...Hi, we just bought a 240v wall heater. My question is this; The heater has a black and a red wire. Our wall wire from the breaker box has a red, black,
white and a ground. It was originally wired to have an external wall thermostat but we ended up buying a heater without that. So, what do we wire to what and what should we do with the extra wire? Thanks!
