3wire appliance to 4 wire supply

Greetings...

I would like to connect a 3 wire cooktop to a 4 wire power supply.

My 3 wire cooktop has 1 black, 1 red, and 1 green wire.

My 240 volt 4 wire home power supply has 1 black, 1 red, 1 white, and a bare copper ground wire.

The instructions say to connect black to black, red to red (of course). They then say to connect power supply bare to appliance green, and to simply cap the white wire with a connector. At the bottom it says (for Canadian installations). It does not have a specific 3 wire to 4 wire diagram "for US installations" .... I live in the US.

These instructions are straightforward enough, but the previous 3 wire cooktop was installed with the home power supplies' white and bare wires both connected to the cooktop green.

So, my question is, do I simply cap the white power supply wire, or twist it in with the green appliance wire/bare power supply wire combo..

thanks...

If your cook top has no white then it is a straight 240 volt appliance. The supply white should just be capped off and the grounds connected, just like the Canadian instructions.

Speedy-

Thanks for the reply. I made the connections, capped the white supply, turned the power back on, and....

It works!


Take Care,
