I am replacing my 20 year old amana cooktop with a new cooktop that fits the exact footprint. I have a question on the wiring of the conduit. The old cooktop is wired as follows:
cooktop red to house white
cooktop black to house black
cooktop yellow to house bare grnd
cooktop bare to house bare grnd

The new cooktop has the following wires:

I believe that I should connect them as follows:
c red to house white
c black to house black
c white to house bare grnd
c green to house bare grnd

Does this sound right? The installation manual says that the cooktop white is neutral and green is ground. The reason I am asking is that the manual says that the house wires should be the same color as the cooktop wires, but my house wires are white, black and bare. I think I would be in trouble if I connect c white to house white!
Thanks, Jim

I suspect you are going to have to install a new branch circuit with a red, black, white, and bare conductor in that cable. As I interpret what you are saying you have a 10 awg cable as a branch circuit serving that cook top. This cable I am interpreting is a 10/2wGrnd nonmetallic sheathed cable {Romex}. If so then you must install a cable in amp rating equal to the name plate rating of that cook top. This may be a 10/3wGrnd or an 8/3wGrnd Romex.

Now if you have an 8 awg or lager cable that has the writing of type SE cable being a red, black, and bare with the bare wrapping around the other two cables then you may be able to use that cable.

You will have to take a close look at what you have as an existing branch circuit cable before we can answer the proper way to wire this new cook top.

Get back to us and tell us if you have a Romex cable or an SE cable serving that appliance. Then we can help you more accurately.

Good Luck

The electrical wires leading to the connection box are under the inaccessable part of the cabinet and I can't see what the wrapping or type of wire it is. Your answer tells me that this will get beyond my expertise and ability for a do-it-yourself project! I am going to pay the experts for installation. Thank you for your help.
