What is covered under Article 382?

Article 382 of the National Electrical Code (NEC) specifically addresses nonmetallic extensions, which are essential for the proper management and protection of electrical conductors in various installations. This article outlines the requirements for nonmetallic raceways that are intended for use in certain applications where metal raceways may not be suitable due to environmental factors, weight considerations, cost, or installation requirements.

Understanding Article 382 is critical for ensuring compliance with industry standards when using nonmetallic materials, promoting safety, and enabling flexibility in design. The guidelines set forth in this article cover aspects such as installation practices, securing methods, and performance criteria to maintain both safety and functionality throughout the life of the installation.

The other options involve different types of raceways or wiring methods that fall under other NEC articles. For instance, cellular metal floor raceways are covered under a separate section that deals specifically with metallic raceway systems and their unique characteristics. Similarly, the code sections discussing metal wireways and strut-type channel raceways define requirements for metallic systems and are not applicable under Article 382. Each article serves to address specific types of materials and their use cases, enhancing the overall structure and safety of electrical installations.
