Where can the requirements for panel board applications in construction be found in the NEC?

  1. NEC Article 406

  2. NEC Article 408

  3. NEC Article 410

  4. NEC Article 412

The correct answer is: NEC Article 408

The requirements for panel board applications in construction are detailed in Article 408 of the National Electrical Code (NEC). This article specifically addresses the installation and requirements for panelboards, including their construction, location, wiring methods, and general installation guidelines. Panelboards are essential components in electrical distribution systems, as they provide a centralized point for circuit protection and control. Article 408 establishes standards to ensure safety and effective operation, including provisions for load calculations, working space around panelboards, and protection from physical damage. The other articles mentioned do cover different aspects of electrical installations, but they do not pertain to panel board applications specifically. Article 406, for example, deals with receptacles, cord connectors, and attachment plugs, while Articles 410 and 412 focus on fixtures and structures related to lighting and associated equipment. Hence, Article 408 is the appropriate reference for understanding the requirements pertaining to panelboard installations.
