Don- I have bee an inspector for 20 years and even when I wore the tools, I don't recall there being a need for GFPE or GFCI for heat tapes. I installed so few of them that I don't remember having a problem at all. Read your CPSC reference- Thank You- My comment would be that the CPSC is not up to speed with the current code on heat tracing. As to the Mobile Home setting, we are not sent to Article 427 for protection but instead ask for GFCI. This type of thing makes me crazy. GFPE is equipment protection and GFCI is people protection. I know you are aware of that and maybe 427 was intended for other than mobile homes. I do think that in other than moblle homes, Article 427.22 applies. Hope we get other comments.
