If you use electric floor heating cables that are embedded in concrete floors of bathrooms or hydromassage bathtub locations, you must wire them with GFCI protection [424.44(G)].

If the thermostat has 5mA built-in GFCI is there a need for the GFCI in the panel?

Thank you in advance!
 
Bathroom GFCI is for 15 and 20 amp 120 volt RECEPTACLES. No receptacle = No GFCI unless the specific piece of equipment requires it (such as a whirlpool tub).

The OP is talking about a heated floor ~ not receptacles or tubs.

424.44(G) Ground-Fault Circuit-Interrupter Protection.
Groundfault circuit-interrupter protection for personnel shall be provided for cables installed in electrically heated floors of bathrooms and in hydromassage bathtub locations.

So GFI protection is required, but how that is to be accomplished can vary.
 
It happens....to me most of the time...LOL

Here's a recent case of foot-in-mouth on my part: #23

Every system I have ever used has a built in GFCI in the thermostat. Makes life a bit simpler on our end ..Especially if you forgot to figure it in.
