Which of the following is a focus of Article 386?

Which of the following is a focus of Article 386?

• A. Cellular Metal Floor Raceways
• B. Surface Metal Raceways
• C. Busways
• D. Multioutlet Assembly

Answer: (B)

Article 386 of the National Electrical Code focuses specifically on Surface Metal Raceways. This article outlines the requirements and considerations for the installation and use of raceways that are mounted on the surface of walls, floors, or ceilings, providing guidelines on aspects such as securing and supporting the raceway, conductor fill, and environmental considerations affecting the installation. Surface metal raceways are utilized to provide an organized and protected pathway for electrical wiring, allowing for easier access to circuits and minimizing the risk of damage to the conductors. By detailing the installation guidelines and safety measures associated with these raceways, Article 386 ensures that electrical installations are both safe and maintainable. Other options listed, while relevant to electrical systems, fall under different articles within the NEC. For example, cellular metal floor raceways are covered in Article 386.10, busways have their regulations detailed in Article 366, and multioutlet assemblies are discussed in Article 393. Each of these other raceway systems has specific guidelines that suit their unique applications, but they are not the primary focus of Article 386.
