Which NEC Article covers low voltage lighting?

• A. Article 410
• B. Article 411
• C. Article 722
• D. Article 726

Answer: (B)

Low-voltage lighting systems are covered by a dedicated NEC article that specifically governs installations where the voltage is limited for safety. This article focuses on the components and practices unique to low-voltage lighting, including transformers or power supplies, conductors, wiring methods, protection, and how these parts interact with grounding and overcurrent protection. The goal is to ensure that the entire low-voltage system is installed safely and reliably, with appropriate sizing and protection for the low-voltage conductors and devices. This is why it’s the best choice: it directly addresses the setup, components, and safety considerations of low-voltage lighting, rather than the general handling of luminaires or lighting equipment that other articles cover. The other articles deal with broader lighting fixtures (not specifically low-voltage systems) or with different circuit classes and methods, so they don’t provide the complete scope needed for low-voltage lighting installations.
