What is the main focus of Article 370 in NEC?

Article 370 in the National Electrical Code (NEC) specifically addresses the installation and requirements for Cablebus systems. Cablebus is a type of electrical raceway that is designed to house and protect electrical conductor systems, providing a solution for efficient power distribution in various settings. The focus of Article 370 includes the construction, materials, installation practices, and performance criteria necessary to ensure safe and reliable operation of these systems.

By covering technical specifications, grounding requirements, and temperature ratings, Article 370 helps ensure that installations comply with safety standards, effectively safeguarding against issues like electrical faults or overheating. The emphasis on Cablebus allows for a systematic and standardized approach to using this equipment, ultimately promoting a safer electrical infrastructure in commercial and industrial environments.

The other options highlight different raceway and assembly types, but they are covered under different sections of the NEC, thus not aligning with the primary focus of Article 370.
