Which article deals with assembly occupancies?

Assembly occupancies are primarily covered under Article 518 of the National Electrical Code (NEC). This article addresses the specific requirements and considerations for electrical installations in venues where gatherings occur, such as theaters, auditoriums, and similar facilities where large groups of people assemble.

The guidelines outlined in this article ensure that the electrical systems in these environments are safe and capable of supporting the unique demands of assembly activities. These considerations include aspects such as emergency lighting, sound systems, and the potential for high occupancy loads, which are critical for maintaining safety and functionality in such spaces.

Other articles focus on different occupancy types or electrical requirements not specific to assembly situations. For instance, Article 516 pertains to hazardous locations, Article 517 covers health care facilities, and Article 525 deals with carnival and amusement park installations. These articles serve distinct purposes that do not address the typical situations or safety concerns present in assembly occupancies, emphasizing why Article 518 is the appropriate choice for this question.
