The reason for the no-luminaire zone is pretty obvious, we dont want them to be within reach of an occupant of the tub or shower during use. Decorative lighting and similar accessories used for holiday lighting and similar purposes, in accordance with 590.3(B), shall be listed. Additional Requirements. Luminaires Connected Together. 410.14 Luminaires in Show Windows. Recessed Incandescent Luminaires. The NEC specifies a few requirements for outlet boxes, inspection, suspended ceilings, luminaire (fixture) studs, insulating joints, raceway fittings, busways, and trees. Recessed luminaires (fixtures) can be installed in the wall or ceiling. Part IV is titled Luminaire Supports. Also in part (B), the clearance to any insulation is required to be at least 3 inches. The issue here is that these luminaires have the possibility of generating a lot of heat, and the lamp is designed to be installed inside a metallic housing, which is then installed at the top of a room in the ceiling. These must be unswitched lampholders. Wiring Supplying Luminaires (Fixtures) Connected Together, VII. Total Cards. General II. Informational Note No. Luminaires and lighting equipment shall be grounded as required in Article 250 and Part V of this article.
