What does Article 368 of the NEC cover?

• A. Wiring systems for residential homes
• B. Busways used as wiring methods
• C. Grounding and bonding requirements
• D. Lighting fixtures and installations

Answer: (B)

Article 368 of the National Electrical Code (NEC) specifically addresses busways, which are systems that conduct electric power and are used as a method for distributing electricity via conductors or busbars encased in a protective enclosure. This article provides regulations on the installation, performance, and safety of busways, ensuring they are robust enough for the demands of electrical systems in commercial and industrial applications. By focusing on busways, Article 368 outlines standards on aspects such as construction materials, load capacities, connection methods, and clearances required for safety and operational efficiency. This surface-mounted or modular wiring method is particularly useful in settings where flexibility and space-saving designs are needed, making it critical for professionals dealing with large-scale electrical systems. In contrast, the other subjects in the choices pertain to different aspects of electrical installations, which are governed by other articles of the NEC.
