Which of the following is covered under Article 545?

Article 545 of the National Electrical Code (NEC) specifically addresses the requirements for manufactured buildings. This article outlines standards related to the electrical installations in these types of structures, which can include prefabricated or modular buildings produced in a factory setting and transported to a site for assembly.

Manufactured buildings often have unique considerations that differ from traditional construction methods, such as specific wiring methods, grounding requirements, and connection standards to ensure safety and compliance with relevant codes. By detailing provisions specifically designed for these buildings, Article 545 helps ensure that all electrical work meets safety standards and adheres to best practices.

In contrast, the other options do not fall under the purview of Article 545. Historic building restorations are typically subject to different regulations related to preservation and safety, commercial warehouses involve more general warehouse electrical standards rather than manufactured specifications, and industrial processing facilities have their own set of guidelines that focus on the needs and hazards associated with industrial operations. Thus, they are not specifically addressed in Article 545.
