Which article is focused on broadcasting equipment?

The focus of Article 810 in the National Electrical Code (NEC) is specifically on broadcasting equipment, particularly related to radio and television broadcasting. This article provides essential requirements for the installation and protection of equipment used for broadcasting, such as antennas, transmission lines, and associated components.

Article 810 includes provisions that address grounding, bonding, and clearance to ensure the safety and reliability of broadcasting installations. The guidelines outlined in this article apply to various broadcasting technologies, ensuring that installations are safe from hazards such as electrical surges and physical damage that could occur during operations.

In contrast, other articles mentioned in the choices pertain to different categories of electrical installations. For instance, Article 820 deals with community antenna television (CATV) and satellite systems, while Article 830 covers network-powered broadband communications systems. Article 860, on the other hand, pertains to information technology systems. Each of these articles targets distinct areas, which differentiates them from Article 810, the one centered on broadcasting equipment specifically.
