Which article would you reference for installation guidelines on indoor wiring methods?

For installation guidelines on indoor wiring methods, Article 300 of the National Electrical Code (NEC) is the appropriate reference. This article covers the general requirements for wiring methods and materials, encompassing the installation of conductors, raceways, and cable assemblies in various settings, including indoors.

Article 300 is comprehensive in its guidelines, addressing aspects such as permissible wiring methods, securing and supporting wiring, and the protection of conductors from physical damage. Understanding the details in this article is essential for ensuring compliance with safety standards and effective functioning of electrical systems indoors.

The other articles listed focus on different aspects. Article 280 pertains to surge protection devices; Article 310 deals primarily with conductors for general wiring, emphasizing their ampacity and installation conditions but does not focus specifically on indoor wiring methods. Article 285 covers communications circuits, which is a different category of wiring altogether. Thus, Article 300 is the best choice for indoor wiring method installation guidelines.
