Since RV Parks, Art 551, is in Chapt 5 does the requirement in 551.71 for 30 amp and 50 amp receptacles allow these particular receptacles to be of the non GFCI protected eve though 210.8 requires outdoor receptacles in these ratings to be GFCI protected ?

Since RV Parks, Art 551, is in Chapt 5 does the requirement in 551.71 for 30 amp and 50 amp receptacles allow these particular receptacles to be of the non GFCI protected eve though 210.8 requires outdoor receptacles in these ratings to be GFCI protected ? Greetings Augie59, It is my opinion that Chapter 5 modifies or amends Chapter 2 in this case and that would align with CMP 7 (formerly 19) panels opinion. The GFCI requirements are clear in 551.71(F) to only apply to 15- and -20 amp receptacles as written in the 2017 NEC, but it did cause much debate and spawned a few Public Inputs. This was presented to the 2020 NEC CMP 7 (formerly 19) regarding this very same question and here is the exact quote from that CMP. (I have access to these things as a CMP Member) "Resolution: GFCI protection requirements are specific to a recreational vehicle park and 210.8(B) does not apply." In the 2020 First Revision, which passed with only 2 negative votes, will be as shown below in the screen capture of Terraview. They never intended 210.8(B) to apply to those RV Park Receptacles that are 30 amps or more. As you can imagine one of the negative votes was NEMA. However the vote carried and will move on to the PC phase. As of right now the CMP doesn't believe GFCI is needed on those RV Park Receptacles 30A or more. Typically the issue of cord and plug applications usually found in 210.8(A) and (B) do present a real "use" hazard. However, it was the opinion of CMP 7 that the 30A and 50A applications for RV Park Receptacles are typically plugged into the coach directly and the receptacles within the RV's are protected accordingly with GFCI protection already. They did not feel people would be randomly plugging items into 30 and 50 amp RV receptacles other than for the RV. So that ended up being their ruling.....210.8(B) can't guarantee the same type of situation.
