Article 518 of the National Electrical Code is focused on which type of occupancy?

Article 518 of the National Electrical Code specifically addresses Assembly Occupancies. This article focuses on the unique electrical requirements and considerations associated with spaces where large groups of people gather, such as theaters, auditoriums, and similar venues designed for entertainment or assembly purposes.

In this context, Assembly Occupancies often have specialized needs for wiring, lighting, sound systems, and emergency systems to ensure safety and functionality when crowds are present. These considerations are critical in preventing hazards such as overcrowding, ensuring adequate egress, and providing proper lighting for visibility and safety, which are paramount in spaces filled with people.

The other options, while related to specific types of occupancies, do not align with the focus of Article 518. For instance, Article 517 covers Health Care Facilities, which involves different requirements necessary for the safety and accessibility of patients and medical equipment. Theaters, although relevant, are actually a subset of the broader category of Assembly Occupancies rather than a defining focus of the article in question. Finally, manufactured buildings have their own set of guidelines that are not covered under Article 518, as they address structural and compliance issues rather than assembly-specific electrical standards.
