Cooktop wiring
Can you please help. I have a new cooktop with red, black and green wires. The house supply is red, black and white wires. The old cooktop was connected red-red, black-black and the copper wire was not connected to the white wire. How would I connect the cooktop? Any help or advice will be appreciated. Thanks.

Banned. Rule And/Or Policy Violation
Welcome to the forums! If your new cooktop has no electronics on it (clock, etc.) then it is a pure 240 volt appliance and will need no neutral. There should be a grounding wire in the junction box. Do you see that? Just cap off the white wire, connect the red and black to the red and black of the stove and the ground/green to the grounding wire in the box. Let us know if you have no grounding wire.

You will have to check with your local electrical/building inspector and see if they allow bonding the ground to neutral.
If bonding is not allowed, you need to install new cable with a bare ground.
The bare ground will be connected to both the metal junction box and the bare wire from the appliance whip.

I see no problem with putting green tape on the white wire and using it as Ground.
Equipment grounding conductors can be bare, covered, or insulated. Insulated equipment grounding conductors size 6 AWG and smaller must have a continuous outer finish either green or green with one or more yellow stripes [210.5(B), 250.119].
