Under the NEC, what aspect does Article 396 cover?

Article 396 of the National Electrical Code (NEC) specifically addresses Messenger-Supported Wiring. This type of wiring is often used in overhead installations where conductors are supported by a messenger wire, which is a structural element typically made of a strong material capable of carrying both the conductors and their weight. The provisions in this article cover how this type of wiring must be installed, the proper distances between supports, as well as ensuring safety and reliability in the electrical installation.

In the context of the NEC, it's essential to adhere to regulations that guarantee the protection of the conductors from environmental factors and mechanical damage, which are critical in preventing potential electrical hazards. Understanding the rules surrounding messenger-supported wiring is important for ensuring compliance with safety standards while providing effective power distribution in various applications.
