Hi,

I have 12/3 running into a sub panel. I wish to hook up my nu heat mat to the black wire (120v) and the red wire to a gfci outlet (120v). I wish to share the neutral. Sticky point is the thermostat of the nu heat mat is GFI protected, so in essence I believe I will have the gfci's sharing the neutral. And yes, I will be putting each one on separate breakers with a handle tie.

The electrician will probably be able to avoid that "sticky point" for you.

my understanding that I cannot share a neutral with 2 gfci's, but was wondering since that it is the thermostat that is gfi protected, it may allow me to share the neutral for the gfci for the bath outlet.

just trying to avoid running another neutral to the panel

however, my instinct tells me that if it walks and talks like a duck, then it probably is a duck

nope, existing contruction. however i did all the electrical work. customer is now remodeling a bathroom and I put some 12/3 in the attic off of the sub panel to pick up future work. just trying to figure out if we can hook up a heat mat on the black wire as the red wire will be used for the dedicated gfci

I wouldn't even try it. Run a new 12/2 and guarantee it.
