What does Article 820 emphasize in its regulations?

Article 820 of the National Electrical Code (NEC) focuses specifically on the standards for signal distribution, particularly as it relates to community antenna television (CATV) and similar systems. This article outlines requirements designed to ensure that the transmission of signals, such as cable television, is safe and effective. It encompasses the installation and maintenance of equipment that is intended for the distribution of video, audio, and data signals within a defined area to prevent interference and ensure reliable service.

This significance is rooted in the need to protect both the public and the infrastructure from issues that might arise due to improper installation and maintenance of wiring and equipment used in signal distribution systems. By enforcing standards, Article 820 helps to assure that signal systems are not only functional but also safe, which is increasingly important as technology evolves and signal distribution becomes more prevalent.
