Messenger-Supported Wiring is covered under which article?

Messenger-Supported Wiring is specifically addressed in Article 396 of the National Electrical Code (NEC). This article outlines the requirements for messenger-supported wiring systems, which typically include overhead wiring that is supported by a messenger wire. Such systems are common in situations where wires must span longer distances without vertical support. Article 396 provides guidelines regarding installation practices, structural requirements, and proper grounding measures to ensure safety and reliability.

Understanding the specific article is crucial for compliance and safety since it specifies how to correctly install and maintain these wiring systems. This ensures that the wires can endure environmental factors and mechanical stress while providing the necessary electrical services. Additionally, it helps prevent hazards such as wire sagging or breaking, which could lead to electrical failures or hazards to the public.

The other articles mentioned (388, 398, and 400) cover different categories of wiring and installations that do not pertain specifically to messenger-supported systems. Thus, Article 396 is the correct reference for those looking to work with or understand messenger-supported wiring.
