I am replacing an electric cooktop and oven. The original cooktop and oven were connected to one 40 amp circuit. The replacement cooktop is calling for a 40 amp circuit and the oven is calling for 30 amps. Can I install both on a the 40 amp circuit?

I think you knew the answer to this before you even posted it. :rolleyes:

Do you currently have copper wiring? Just curious>

Yes I have copper wiring.

So that's 10 Amps per burner and 30 Amps for the oven. So if you installed it on a 40 Amp circuit, you could elither use all 4 burners or 1 burner and the oven. I doubt the SO would like that.

Guess what the answer is?
