When an EV and EVSE are used to facilitate power supply as an interactive power production source, which article must be applied?

• A. Article 705
• B. Article 700
• C. Article 702
• D. Article 704

Answer: (A)

When an EV and its charging equipment are used to supply power back to the building or the grid, the vehicle becomes a distributed energy resource that must be interconnected with the building’s electrical system. This scenario is governed by Article 705, which covers Interconnected Electric Power Production. It lays out how on-site generation and energy storage sources connect to the premises wiring and to the utility, including how they are synchronized, how protective devices and disconnects are arranged, and how anti-islanding protections are implemented to ensure safety during outages. Since the EV/EVSE setup can export power and involves control of a production source with the electrical system, Article 705 is the applicable standard. Other articles address different situations (such as emergency or standby systems) and not this interconnection of a vehicle-based production source.
