Which NEC article outlines the specific sizing requirements for grounding electrode conductors used for network-powered broadband communication systems?

The correct choice highlights Article 800 of the National Electrical Code (NEC), which specifically addresses communications circuits, including the sizing requirements for grounding electrode conductors utilized in network-powered broadband communication systems. This article encompasses the requirements necessary to ensure safety and proper functioning of communication systems by detailing how grounding should be implemented.

Article 800 includes provisions that guide the installation and grounding of communication circuits, ensuring that these systems are protected against electrical disturbances and contributing to the overall safety of the electrical installation. Proper sizing of grounding electrode conductors is critical for effective grounding, minimizing the risk of electrical shock, equipment damage, and interference in communication systems.

In contrast, Article 700 pertains to emergency systems, Article 810 covers television and radio equipment, and Article 400 deals with flexible cords and cables, none of which specifically address the requirements for grounding electrode conductors in broadband communications. Thus, they do not provide the relevant guidance found in Article 800 for the specified context of the question.
