NEC Article ___ covers energy storage systems.

• A. 706
• B. 690
• C. 691
• D. 705

Answer: (A)

Energy storage systems have a dedicated NEC article that covers their installation and safety. This article sets the rules for how storage equipment—such as battery banks and other storage technology—connects to and is protected within a building’s electrical system, including wiring methods, disconnects, overcurrent protection, interconnection, labeling, and safety practices. It helps distinguish storage equipment from other topics like photovoltaic systems, which are covered under a different article, and from other solar or power-production topics. The result is a focused set of requirements that specifically address the unique risks and installation considerations of energy storage equipment, making it the best fit for questions about which article governs energy storage systems.
