Article 830 covers which type of systems?

Article 830 of the National Electrical Code specifically addresses network-powered broadband communications systems. This section focuses on the installation, safety, and performance requirements for systems that provide broadband telecommunications, which includes various forms of data transmission and communication networks.

Network-powered broadband communications systems typically rely on power and data to function, often utilizing both coaxial and fiber optic cables, and may include technologies such as cable internet, digital subscriber lines (DSL), and other high-speed data services. The standards laid out in Article 830 ensure that these systems are installed in a way that protects both the infrastructure and the users from electrical hazards.

The other types of systems mentioned are covered under different articles within the NEC. For instance, residential lighting systems are addressed under a separate article that focuses on residential installations, emergency power systems have their own specific requirements outlined in another part of the code, and television broadcasting systems, while related to communications, are governed by different regulations that are not specified within Article 830. Thus, the focus on broadband communications systems is what distinguishes Article 830 from those other topics.
