Which article encompasses theaters and audience areas of motion picture studios?

Article 520 of the National Electrical Code specifically addresses the requirements for theaters and audience areas of motion picture studios. This article is crucial because it outlines the unique electrical characteristics and safety considerations necessary for environments where performances are staged, ensuring the safety of audiences and performers alike.

Theaters and audience areas have specific lighting and power needs, including the usage of stage lighting, sound systems, and other electrical equipment that must be safely integrated into these environments. Article 520 provides regulations pertaining to the installation of electrical systems in these settings, addressing aspects like circuits, wiring methods, and equipment location to minimize hazards such as electrical shocks and fires.

Other articles listed in the choices cover different types of facilities or specific electrical systems not related to theaters. For instance, Article 530 pertains to motion picture and television studio circuits, but it does not specifically target audience areas as thoroughly as Article 520 does. Understanding the content of Article 520 is essential for professionals working in the entertainment industry to ensure compliance and safety in theatrical and studio settings.
