Code Change Summary: Revised language pertaining to branch circuits for electric vehicle charging.
Section 625.40 in the 2020 NEC® required all electric vehicle supply equipment (EVSE) to be supplied by an individual branch circuit that serves no other outlets regardless of the size (or level) of the vehicle charger.
There are three levels of EV charging:
In the 2023 NEC®, a public input was accepted to remove the code language previously requiring an individual branch circuit for ALL EVSE outlets. The revised 2023 language in Section 625.40 now requires an individual branch circuit only for EVSE outlets greater than 16 amperes or 120 volts. Additionally, a new exception to 625.40 now allows branch circuits to feed multiple EVSE’s as permitted by 625.42(A) or (B).
The previous rule requiring an individual branch circuit for all EVSE outlet applications was excessive for level 1 charging.

2023 Code Language:
625.40 Electric Vehicle Branch Circuit. Each outlet installed for the purpose of supplying EVSE greater than 16 amperes or 120 volts shall be supplied by an individual branch circuit.
Exception: Branch circuits shall be permitted to feed multiple EVSEs as permitted by 625.42(A) or (B).
