GFCI for EV charging receptacles

What the code requires

All receptacles installed for EV charging must have ground-fault circuit-interrupter (GFCI) protection for personnel. That includes larger receptacles, such as a NEMA 14-50 used for a plug-in charger, whatever the voltage or amperage.

In the 2023 edition the rule covers receptacles only, so a hardwired charger is outside 625.54. Revisions proposed for the 2026 NEC would extend the rule to hardwired outlets and add special-purpose GFCI (SPGFCI) for EV equipment over 150 V to ground. Neither is a 2023 requirement.

On the job

• If a charger plugs into a receptacle installed for it, that receptacle needs GFCI protection.
• Mike Holt notes that dwelling-type GFCI breakers and receptacles aren't suitable for backfeeding, so bidirectional chargers end up hardwired.

In California

CALGreen requires NEMA 6-20R, 14-30R or 14-50R EV receptacles in new multifamily buildings. They are installed for EV charging, so this GFCI rule applies to them.
