I am finishing my basement and have run all of the wiring from the panel to the wall where the thermostat will be and from there I have run the wire to the two locations where the heaters will be mounted. I am going to use a 6ft Fahrenheat and an 8ft Fahrenheat. They are 240v and I will be using the thermostat to control both together. My question is did I make a major mistake by running 10/3? As I have been reading here the last couple of days, it seems everyone is using 12/2. When I first decided to run the wires a couple of months ago, I thought I needed 10/3 since both heaters would be wired together. Please let me know if I can just wire nut the white or if I have to re-run all of the wire. Re-running the wire would not be good since I have already put up the wallboard and taped and spackled.

Any help would be GREATLY appreciated!

Thanks!

The 10/3 will work, but you could have used 12/2. First off, #10 is oversized for what you are doing. Also, there was no need for "3-wire". You are allowed to use the white as a hot conductor for a straight 240v circuit such as you electric heat.

Thanks for the reply. Am I safe to assume then that I can just terminate the white as I will not need it?

Taz,

Just curious, what is the amperage required by these heaters? It should stamped on the manufactures tag on each unit.

What white wire you talking about?

The amperage is as follows:
8ft heater - 8.3 amps
6ft heater - 6.3 amps

I used 10/3 wire which if I am not mistaken has RED, WHITE, BLACK, and GROUND.

Okay. So I am a HUGE idiot! I went down in to the basement last night to look at my wiring and I rememebered that I had done a fair amount of research before wiring the basement. I did in fact use 10/2 wire for the baseboard heaters. I think the reason I had bought the 10/2 originally was because I thought I was going to have more amperage than what I have actually wound up with. Anyway, I have it all taken care of. It has just been a few months since I did the wiring so I had forgotten.
Thanks for the input anyway guys!
