Art 426.28 requires GFPE protection for deicing and snow melting equipment. What would is the advantage to using GFPE vs GFCI? GFCI I believe trips at 5ma where GFPE trips at 30ma, so I would think GFCI protection would actually be safer. Would nuisance trips occur?
I'm not trying to circumvent the code but just curious why GFCI would not be allowed. I must admit, I have never even seen a GFPE breaker.
Thanks
