Messenger-Supported Wiring is covered under which article?

Messenger-Supported Wiring is specifically addressed under Article 396 of the National Electrical Code (NEC). This article outlines the requirements and guidelines for the installation and use of messenger-supported wiring systems. Such wiring typically includes overhead conductors that are supported by a messenger wire, which is intended to provide structure and support for the conductors it carries.

Article 396 includes important provisions concerning the installation practices, support arrangements, and the types of conductors that can be used. These requirements are crucial for ensuring a safe and reliable distribution of electrical power, particularly in applications where wires need to be suspended in the air.

In contrast, while other articles such as Article 388, Article 398, and Article 400 address different types of wiring methods, they do not specifically cover messenger-supported installations. Article 388 deals with low-voltage and medium-voltage cables, Article 398 covers the requirements for open conductors and open drop conductors, and Article 400 focuses on flexible cords and flexible cable installations. Each of these articles has its distinct scope and specific applications that do not overlap with the provisions provided in Article 396.
