The supply has black, red, white and ground. So does the stove. The cooktop only has black, red and ground. What do I do with the white wire from the stove? Connect it to the white on the supply, or combine it with the ground?



  • That's an easy one, because neutral and ground are both supplied. It gets harder in older installations without ground. – Harper - Reinstate Monica Apr 19 '19 at 17:59

In this case, you connect like to like.

The cooktop does not have a neutral (white) wire.

This is perfectly fine. The cooktop has no 120Volt loads, so it does not NEED a white wire.

[ The concerning case is when an old device has black, red, & white, but no ground (green or bare) ]
