Which NEC article covers the installation of luminaire support and mounting in ceilings?

• A. Article 392 (Cable trays)
• B. Article 215 (Feeders)
• C. Article 110 (General safety)
• D. Article 410 (Luminaire mounting)

Answer: (D)

Installing luminaire support and mounting in ceilings is governed by the NEC section that covers luminaires themselves. This part specifies how fixtures must be mounted and supported, what kinds of mounting hardware are acceptable, and how mounting methods must align with the fixture’s listing and the location (such as ceilings). It also covers the use of approved boxes, canopies, and other mounting interfaces, along with any clearance or environmental requirements tied to the fixture. The other topics mentioned—cable trays, feeders, and general safety—address different parts of electrical systems and do not specify how luminaires should be installed or supported.
