What type of facilities does Article 517 pertain to in the National Electrical Code?

Article 517 of the National Electrical Code specifically focuses on health care facilities. This article outlines the requirements necessary to ensure electrical safety and proper function in areas where patients receive care. These requirements account for the unique needs of health care environments, such as critical electrical systems that support life-saving equipment and systems designed to protect patient safety, including grounding, separation of circuits, and the configuration of wiring systems.

Health care facilities often have a greater risk due to the presence of medical equipment, vulnerable patients, and the potential for failure if electrical systems do not function properly. Consequently, the NEC emphasizes methods and standards tailored for hospitals, clinics, and similar establishments.

In contrast, the other options, although they all pertain to their respective areas within the NEC, do not fall within the jurisdiction of Article 517. Assembly occupancies, mobile home parks, and agricultural buildings are governed by different articles that address their specific needs and risks.
