Which NEC article specifically addresses luminaires and their installation?

• A. Article 500 covers luminaires.
• B. Article 210 covers luminaires.
• C. Article 410 covers luminaires.
• D. Article 300 covers luminaires.

Answer: (C)

Luminaires and their installation are addressed by a dedicated article that covers the requirements for lighting fixtures, lampholders, and lamps. This article lays out how luminaires must be installed, including how they are mounted, how wiring connections inside or to the fixture are made, and how location and enclosure (such as damp or wet environments) affect what is allowed. It also covers listing and labeling considerations and the need for a disconnecting means for servicing the fixture. While other articles deal with related topics—hazardous locations, branch circuits for lighting, or general wiring methods—the specific rules for luminaires and their installation are contained in this article, making it the correct reference for questions about luminaires.
