The National Electrical Code® (NEC®) now requires a GFCI breaker on the circuit if you are using a 6-50 or 14-50 outlet. Since the Emporia EVSE already has a GFCI, and since two GFCI with different sensitivities on the same circuit can result in unwanted tripping, you'll want to hardwire our Emporia EV Charger on a dedicated breaker, which allows it to be installed on a breaker without GFCI protections.
