Which NEC® article covers solar PV systems?

• A. Article 690
• B. Article 705
• C. Article 694
• D. Article 710

Answer: (A)

The main idea is that solar photovoltaic systems have a dedicated NEC article that covers their installation from modules and wiring to protection and safety features. This article specifically deals with PV components like modules, inverters, combiner boxes, wiring methods, conductor sizing, overcurrent protection, and the required disconnects, grounding, labeling, and rapid shutdown provisions. Because it directly addresses how a PV system is built and put into service, it’s the most relevant and authoritative reference for designing and inspecting solar installations. When a PV system connects to a building’s electrical system or the utility, you’ll also consult the related rules for interconnected electric power production sources to handle how the PV output interfaces with the service and the grid. There are other NEC articles for special cases, such as microgrids or standalone systems, but for a typical solar installation, the PV-specific article is the primary guide.
