Article 800 of the National Electrical Code (NEC) specifically addresses communications circuits. This article outlines the requirements for the installation and maintenance of communication systems, which include a variety of technologies such as telephone lines, data transmission lines, and other forms of telecommunication wiring.

The regulations in Article 800 are crucial for ensuring safety, reliability, and performance of communication circuits, which can encompass both low-voltage and high-voltage systems. Compliance with this article ensures that communication wiring is adequately protected from physical and environmental hazards, and that it adheres to established standards for performance.

In contrast, other options like fire alarm systems, general wiring, and standby power systems are governed by different NEC articles. These articles cater to the specific requirements and safety guidelines pertinent to those respective categories of electrical systems, further underscoring why communications circuits are the primary focus of Article 800.
