Is the GFCI protection for a pool heat pump required to be the 5ma type? (Heat pump installer recommends a 20ma to avoid nuisance trips)
5ma GFCI vs 20ma GFCI

I believe that the old Class B 20ma standard was for pool lights from the 1970's. I don't have my codebook but isn't 5 ma Class A required?

The 20ma is an SPGFCI and is only for equipment supplied by circuits exceeding 150 volts to ground. I have not reviewed 680 recently but don't believe a heat pump requires GFCI/SPGFCI protection. I could be wrong though.
