What type of equipment does Article 810 primarily address?

Article 810 of the National Electrical Code specifically deals with the installation and safety requirements for radio and television equipment. This article outlines the guidelines to ensure that such equipment operates safely and effectively, taking into consideration factors such as grounding, bonding, and wire type. The focus on radio and television encompasses various elements like antennas and their associated components, which are critical for maintaining signal quality and preventing electrical hazards.

The context around the other options highlights their relevance but distinguishes them from the primary focus of Article 810. Community antenna systems, while related, are typically addressed more specifically under separate provisions in the code. Network-powered broadband systems, although crucial for modern telecommunications, fall under different articles of the NEC. Telecommunication lines, likewise, are more broadly covered in other sections that focus on wiring and installation specific to telecommunication infrastructure. Thus, option B captures the essence of Article 810's directive on radio and television equipment.
