Since the intent of 551.71(F) in not requiring GFCI protection for RV 30 & 50 amp hookups is based the fact that the RV cord a feeder, and the RV provides it's own GFCI protection, would this apply to an RV hookup at a dwelling? The circumstances of the RV don't change, only the location, however the exception is only mentioned in 551 which deals with RVs and RV parks, it is not mentioned in 210 which deals with dwelling units. Do you believe this was an oversight and as an inspector what would be your call?
