Which NEC article covers the general requirements for wiring systems in theaters and similar occupancies?

• A. Article 410 (Luminaire mounting)
• B. Article 500 (Hazardous locations)
• C. Article 520 (Theatrical)
• D. Article 215 (Feeders)

Answer: (C)

The essential idea here is identifying which NEC article specifically covers wiring systems for theaters and similar occupancies. The article that focuses on this area is Theatrical, which sets out the electrical installations used in theaters, cinemas, stages, and comparable venues. It addresses distribution of power to stage lighting and equipment, dimming systems, control wiring, backstage and audience-area circuits, and safety provisions unique to theatrical environments. This means it provides the specialized rules for how theater wiring and equipment must be installed and protected, beyond general building wiring.

The other options don’t fit as well. Luminaire mounting covers only how lighting fixtures are mounted, not the full wiring system in a theater. Hazardous locations deals with classifications for locations with flammable hazards, which is not the general scope of theater wiring. Feeders and branch circuits for general commercial or industrial occupancies cover broad power distribution, but they lack the theater-specific provisions for stage lighting, dimming, and control systems.
