Wiring a Sauna heater

240vheaterwiring

I was wondering about the correct way to wire a 240V sauna heater/thermostat in a sauna I have built.

From the heater I have a black, white, and bare wire. The black and white connect to separate terminals on the thermostat switch, the bare goes to the ground nut.

Under the house is a 120V/240V GFCI. From that I have a Black(hot), Red(hot), White(neutral), and bare wire. I figured I will connect one of each hot wires to the heater's black/white wires via the thermostat switch. The bare wire will go to the ground nut. I was wondering what happens with the white wire in this case?

I've read it is bad practice to tie the neutral to the ground so what do I do with it?

If your sauna heater is a 240 volt heater, you don't need the grounded (neutral) conductor. You can simply cap it off using a twist-on wire connector, or other approved means.
