What is the focus of Article 645 in the National Electrical Code?

Article 645 of the National Electrical Code specifically addresses the requirements for Information Technology Equipment (ITE). This article covers the installation, operation, and safety considerations that must be accounted for when dealing with equipment such as computers, servers, and associated peripherals typically found in data centers and similar environments.

The article focuses on the unique needs of ITE, including considerations for power distribution, cooling, and fire safety, which are essential for maintaining the operation and integrity of information technology systems. Additionally, Article 645 sets standards for pathways, spaces, and equipment that are specifically designed for the high-density environments of modern IT installations, thereby ensuring that they operate efficiently and safely.

The other topics listed do not fall under the purview of Article 645. For instance, electrolytic cells are covered in different sections that pertain to specific electrical equipment and their methodologies. Induction and dielectric heating equipment also have dedicated articles addressing their particular safety and installation standards. Electric vehicle charging systems are guided by other parts of the NEC specifically formulated to handle the unique characteristics of EV charging.
