Well then it isn't as useful as I thought. It would make more sense if the cmp who wrote the section to do the explaining.Paid editorial staff of the NFPA, just like the comments in the Handbook.
They are not paid people and spend a lot of time doing the required code changes work.Well then it isn't as useful as I thought. It would make more sense if the cmp who wrote the section to do the explaining.
I thought that amendment was for the garage door receptacle up top.So since North Carolina has not adopted the 2020 code for single and two family dwellings. Meaning that they are still operating in the 2017 code. From my understanding I don’t have to install gfci protection on any 30 or 50 amp 240v receptacles located in the garage or outside for vehicle charging.
My question concerns a couple specifics. It is my understanding that any outdoor outlet has to be GFCI protected now including RV hookups.
But won't this cause plenty of issues seeing as the RV may already have GFCI's installed throughout? Or will this not be an issue?
Same goes for EV chargers, many say in the manual to not put on a GFCI breaker because they already have it internally. So does that eliminate the option of being able to have a cord and plug install if the receptacle is outdoors or in a garage?
thanks
There was a TIA for RV parks, but that does not change the requirement for outside outlets for dwelling units required by 210.8(F) that may be used for RV trailers.It's my understanding the requirement for 30A and 50A RV outlets to be GFCI proctected was reversed and they are no longer required to be GFCI protected by the 2020NEC.

The outlet is the connection point between the building wiring and the equipment.What are we considering the "outlet" in a hardwired charging station like the Gen 3 wall connector?
It does have integrated GFCI protection and all the wiring is inside the wall connector.
That connection point is the wall connector.The outlet is the connection point between the building wiring and the equipment.
While the EVSE likely has ground fault protection internally, it may not have the 4-6ma trip level required for it to qualify as a GFCI. Also, as it is downstream of the outlet, it does not protect the outlet.

Well, it's the point inside the wall connector's wiring compartment where you land the building wire.That connection point is the wall connector.
The receptacle itself, or perhaps the wipers in the receptacle. So with the receptacle, the GFCI circuitry inside the receptacle protects the outlet. While with the EVSE, the ground fault circuitry within it does not protect the outlet, only the EVSE cord and downstream.I'll have to check on that trip level, but what would we consider the outlet on a standard GFCI receptacle outside next to the breaker box?

Agreed, but it doesn't say GFCI. So that "listed system" may not qualify as a GFCI. I haven't checked the UL listing standard for EVSEs to see what it says.625.22 requires the equipment to “have a listed system of protection against electric shock of personnel.”
Assuming that's for a generator, I would say it's not an outlet as inlet seems to me to be the opposite of outlet.Would a 30 amp flanged inlet installed on the exterior of a dwelling unit in a readily accessible location be considered as an outlet?
The point of GFCI isn't to protect wires or equipment, it's to protect people. The question is what is the upstream-most (closest to power source) point at which leakage current to ground will cause the GFCI to trip? That point needs to be upstream of the outlet in order for the outlet to be protected. If the (hypothetical) GFCI protection is within the equipment, the outlet is not protected.In both situations, when the GFCI trips due to an issue, it will shut down the device/equipment, thus protecting the wires.
