Which article specifically addresses information technology equipment?

Article 645 of the National Electrical Code (NEC) specifically addresses information technology equipment (ITE). This article applies to the installation of equipment that performs both information and communication tasks, primarily focusing on computer systems and related technology. It outlines practices that ensure safe and effective installation while considering factors such as power supply, grounding, and overall safety measures to mitigate risks associated with the operation of such equipment.

Information technology equipment often requires special considerations due to their environments, such as data centers, that demand enhanced cooling, fire safety measures, and specific power distribution arrangements. Article 645 provides directives for managing these requirements, ensuring compliance with safety standards, and protecting both equipment and personnel from electrical hazards.

Other articles mentioned do not specifically cover information technology equipment to the extent defined in Article 645. For instance, Article 647 deals with the grounding and bonding of information technology equipment but is focused more on the electrical safety aspect rather than the installation specifications. Article 626 is related to the installation of electric elevators and escalators, while Article 640 pertains to audio and video equipment. Hence, Article 645 is the most appropriate and relevant article concerning information technology equipment.
