What is the specific article of the NEC that outlines the grounding and bonding requirements for an information technology room?

The grounding and bonding requirements for an information technology room are specifically outlined in Article 645 of the National Electrical Code (NEC). This article focuses on the provisions related to communications equipment, including the installation, arrangement, and protection of systems found in information technology environments.

Article 645 emphasizes the importance of proper grounding techniques to ensure the safety and reliability of the equipment, protecting it against electrical faults and surges. This is crucial in IT rooms where sensitive electronic devices are used, as improper grounding can lead to equipment damage or malfunction.

In contrast, the other articles mentioned do not specifically address the needs of information technology rooms. Article 605 relates to low-voltage systems and does not cover the broader scope of requirements for information technology spaces. Article 715 deals with the requirements for additional interconnected systems and platforms in commercial settings, while Article 770 focuses on the installation of fiber optic cables. Therefore, Article 645 is the most relevant and specific to grounding and bonding requirements in information technology rooms.
