Change Summary

• New section requires an outlet installed for electric vehicle charging loads be provided with a separate (individual) branch circuit
• A new Section 210.17 titled Electric Vehicle Branch Circuit has been added to Article 210
• The revision aligns with the load profile requirements for electric vehicle supply equipment (EVSE) and correlates with Sections 210.19(A)(1) and 210.23

Expert Analysis

This new section provides clear requirements for installing separate (individual) branch circuits for electric vehicle supply equipment (EVSE) where necessary for vehicle charging. Charging loads associated with electric vehicle supply equipment are continuous duty loads. Generally, these loads shall not exceed 80 percent or the conductor capacity or 80 percent of the rating of the branch circuit overcurrent device. The current load profiles of levels 1 and 2 electric vehicle supply equipment are such that in order to comply with 210.19(A)(1), 210.20(A)(1) and 625.40, individual branch circuits must be installed. This rule applies even to branch circuits used for cord-and-plug connected types of EVSE. As required in 625.5, electric vehicle supply equipment is required to be listed. The installation instructions with this equipment typically require connection to an individual branch circuit. This new
section in Article 210 provides users with more specific individual branch circuit requirements that apply to occupancies where electric vehicle supply equipment is installed and used.
