Which NEC Article covers Community Antenna Television and Radio Distribution Systems?

• A. NEC Article 800
• B. NEC Article 820
• C. NEC Article 830
• D. NEC Article 727

Answer: (B)

The key idea here is that the NEC assigns a specific article to each type of low‑voltage distribution, and community antenna television and radio distribution has its own dedicated article. This article lays out the rules for installing and wiring CATV and radio distribution networks, including the types of conductors and equipment used, how they’re powered and protected, and how grounding and bonding should be handled to keep the system safe and reliable. It covers the pathways, terminations, and devices involved in distributing TV and radio signals within a building or community system, so installers know exactly what is allowed and what isn’t. That’s why this article is the right one: it is the official reference for CATV and radio distribution systems, separate from general communications circuits, which are covered under a different article, and separate from network-powered broadband systems, which involve other specific provisions. The other articles address different kinds of wiring and systems, so they don’t govern CATV distribution in the same focused way.
