Which NEC article covers energy storage systems and where are they primarily covered?

• A. Article 706 covers energy storage systems.
• B. Article 710 covers energy storage systems.
• C. Article 725 covers energy storage systems.
• D. Article 760 covers energy storage systems.

Answer: (A)

Energy storage systems are addressed in NEC Article 706. This article is dedicated to electrical energy storage systems and lays out how these systems are installed, how they connect to the building wiring, the protection and disconnection requirements, labeling, enclosure and ventilation considerations, and safe interconnection with the rest of the electrical system. The NEC uses Article 706 to group all aspects of ESS in one place because they present specific safety concerns—such as thermal management, charge/discharge control, and fire safety—that differ from other electrical installations. While components like storage batteries have historical ties to other articles, the primary coverage for energy storage systems as a whole sits with Article 706.
