Which NEC article covers outdoor lighting and luminaire installation?

• A. Article 300 covers outdoor lighting.
• B. Article 410 covers outdoor lighting and luminaire installation.
• C. Article 500 covers outdoor lighting.
• D. Article 210.52 covers outdoor lighting.

Answer: (B)

The main concept here is understanding which NEC section governs the equipment used for lighting and how it should be installed. Luminaires, lampholders, and lamps are addressed in the article that sets the requirements for lighting fixtures, including their wiring, mounting, and installation. This means outdoor lighting fixtures are covered under this same article, since it focuses on the fixtures themselves and how they’re properly installed, whether indoors or outdoors.

Other topics listed are about general wiring methods, hazardous locations, or receptacle outlets in dwelling units, which do not specifically cover the installation requirements for luminaires. So the article dedicated to lighting fixtures and their installation is the one that applies to outdoor lighting as well.
