What kind of venues are discussed in Article 520?

Article 520 focuses specifically on the requirements and regulations pertaining to theaters, audience areas of studios, and performance areas. These venues are distinct because they often have unique electrical and safety needs due to the nature of performances, lighting, and the presence of audiences. The article outlines standards for these types of spaces to ensure safety, proper electrical performance, and the functionality necessary for live events.

In the context of electrical codes and safety standards, theaters and similar venues require specialized considerations for stage lighting, sound equipment, and emergency systems, which may not apply to other types of spaces like sports arenas or amusement parks. Consequently, the regulations outlined in Article 520 are tailored to address the complexities and specific risks found in spaces designed for live performances, making this choice the most relevant in the context of the question.
