We have black and white coming in and black, red, and white on the cooktop. which wires go together?
Hi, I'm sure by now you probably have this fixed. Anyway, It is important that you know some information, like what the voltage is of the black and white wires coming in. The electrical codes in most places call for the 3rd wire which would be a neutral. If the old wiring has a metal conduit it is possible that it is being used as a ground and it may have been assumed that if the ground and neutral wires in the distribution panel were connected to the same bus that it wouldn't matter. Not the safest way to go but it will still work if you have no other wires. The incoming would probably be each a 110vac leg which the black would connect to black and the red from the cooktop would connect to the white of the incoming and the white of the cooktop would be sealed off. If you need additional help please let us know. Good Luck!
