Was it 2020 code that implemented GFCI breakers on EV charger receptacles in a residential garage or was it in before that?
 
First required in the 2020 for the receptacle. 625.54
Seems like the chargers themselves have a GFCI function built into them also.

The charger I just installed had no neural wire

Also a charger is not a receptacle

I would avoid putting in receptacle outlets for chargers, stay with the ones that can be hard wired.
 
I just looked at a EV installation at a dwelling. 240 volt 50 AMP Unit. Charger can be hard wired or plug. Installation will have to comply with 2020 NEC.

  • If I hard wire the charger in the garage then GFCI protection not required. 210.8 A (2) states "Receptacles" in Garage. NOT OUTLETS. Also 625.54 again states " Receptacles ".
  • If I put charger outside then I have to comply with 210.8 F which states " Outlets ". Then it has to be GFCI protected.

A 50A unit would require a 60A branch circuit, which according to 625.44 requires hard-wiring, receptacle is not allowed. GFCI is only required 50A or less (210.8(F)), so 60A hard-wired outdoors would not require GFCI.

That’s how I interpret things….
 
THANK YOU. You made me read the rest of the paragraph. Now I see that up to 50 AMPS for GFCI protection. So 60 AMP outlet would not require GFCI protection (210.8(F))

I got to thinking more about this. I’ve never seen a 50A EVSE. They’re normally 48A for a 60A circuit. If it’s truly 50, a 60A circuit is not sufficient - 50 x 1.25 = 62.5.
