Which article would you refer to for guidelines on network-powered systems?

The correct choice focuses on Article 830, which specifically addresses network-powered systems, particularly for information technology equipment and communication systems. This article provides the necessary guidelines for low-voltage communication circuits and covers aspects such as cabling requirements, installation practices, and safety protocols for network-powered systems.

Understanding the significance of Article 830 is essential for professionals working with data communication and networking technologies, as it delineates the standards and best practices for these systems, ensuring proper installation and operation while minimizing risks associated with electrical components in network environments.

The other articles mentioned cover different aspects of electrical codes; for example, Article 810 deals with radio and television equipment, Article 820 pertains to community antenna television and radio distribution systems, and Article 840 relates to remote control, signaling, and power-limited circuits. Therefore, when dealing specifically with network-powered systems, Article 830 is the most relevant and provides the needed guidance.
