EV Charger GFCI Receptacle Requirements

[atohmselectric]

I'm installing a EV charger that requires a NEMA 6-50 receptacle. The system is a 120/208 3 Phase 4 -wire system. It's a cutler hammer panelboard that utilizes bolt on circuit breakers. To my knowledge there is no GFCI circuit breaker to accommodate this panel. I'm under the 2017 NEC requirements. I'm required to install a dedicated branch circuit that has no other outlets and because its outdoors, less than 150V measured to ground, 50A or less and cord and plug connected, single phase it requires GFCI protection. Any ideas how I can accommodate these requirements without the use of a GFCI circuit breaker at single phase 208V at 40A using a 6-50 receptacle? Do they make a single standalone GFCI breaker encloser, or should I utilize something for SPA's?

I will double check my book. But if I remember correctly the 240V GFCI requirement started in 2020 cycle.

Where are you installing the receptacle that requires GFCI protection under the 2017 code?

625.54, however I just noticed in my other 2017 code book that article number doesn't exist in 2017 NEC. There is a grey letter N next to the article in this specific 2017 version I have, however when I look into my NEC 2017 Handbook 625.54 doesn't exist. I imagine the grey N is indicating a change.

It is in the Link version of the 2017 code.
Do the instructions have provisions for hard-wiring the charger? If so, that would eliminate the GFCI requirement.
There are Stand Alone GFCI devices available, if the charger cannot be hardwired.

You are correct, thank you. Although the unit came with a molded plug and cord already attached, the installation instructions do indicate it can be altered to accommodate hardwiring as an additional means of connection, therefore eliminating a receptacle and GFCI protection requirements as you indicated, and no disconnecting means are required under 60A.

IIRC, 625.54 is a TIA for 2017. So whether it applies would depend on whether your jurisdiction adopted the TIA.

That is one of the issues with Link....they don't tell you that the wording is from a TIA resulting in enforcement issues, because as you say, the TIAs must be adopted by the agency that adopted the code to be legally enforceable.
Changes are made in Link as soon as they have bee accepted by the NFPA.

Go get yourself a "spa panel kit". This is typically a 2 slot 3R panel that comes with a 50A GFCI breaker. Eaton makes them using the clip on CH breaker, but many other vendors make them too. It is also typically the cheapest way to buy a 50A 2 pole GFCI breaker.
