Article 830 covers which type of systems?

Article 830 of the National Electrical Code (NEC) specifically addresses network-powered broadband communications systems. This article is focused on the installation and maintenance of equipment and wiring that deliver broadband communications over various mediums, such as coaxial cables and fiber optics. It sets forth requirements that ensure safety, performance, and reliability in the installation of these systems.

Broadband communications systems are essential for the transmission of data at high speeds, which is crucial in today's technological landscape where internet connectivity is vital for both residential and commercial usage. The article provides guidelines on the proper handling, installation, and maintenance of these systems to prevent electrical hazards and ensure efficient operation.

The other answer choices discuss systems that fall under different parts of the NEC. For instance, residential lighting systems are covered under different articles focused on general wiring and lighting specifics, while emergency power systems have their own guidelines to ensure safety during power outages. Television broadcasting, although related to communication, is not directly addressed by Article 830 since it pertains more to the infrastructure of delivering TV signals rather than broadband communications systems themselves.
