Which article contains regulations for audience areas in theaters?

The correct response is based on the fact that Article 520 of the National Electrical Code (NEC) specifically addresses the electrical requirements for theaters, including audience areas. This article outlines crucial safety standards and installation guidelines that ensure the safety of both patrons and performers in theatrical settings.

Key aspects covered under Article 520 include requirements for wiring, equipment, and installations in areas where performances occur, including stages, audience areas, and backstage sections. These regulations are essential for minimizing electrical hazards and ensuring safe operation, as theaters often have unique lighting and sound requirements that differ from typical commercial or residential installations.

Through a focused approach, Article 520 helps to ensure that all electrical systems in theaters are sufficiently designed to handle specialized equipment while maintaining compliance with safety codes, thus providing a safe environment for the audience and ensuring proper functionality during performances.
