NEC Article ___ covers interconnected electric power production sources.

• A. 690
• B. 705
• C. 691
• D. 706

Answer: (B)

When more than one power source feeds the same building circuit, the connections must be managed so everyone stays safe and the system operates reliably. That scenario is addressed by NEC Article 705, which covers interconnected electric power production sources. It explains how distributed energy resources like solar photovoltaic systems, generators, and energy storage can be connected to a circuit that may also be supplied by another source, and it lays out the protections, disconnecting means, conductor sizing, grounding, and coordination required for a safe, functional interconnection. It also covers labeling, metering, and how the interconnection point is arranged to ensure the utility can safely disconnect the system if needed and prevent backfeeding during maintenance. The other articles deal with standalone generation or different topics, not the specific interconnection of multiple power sources, so Article 705 is the right reference.
