Which article would you consult for electrical installations in hospitals and clinics?

• A. Article 800
• B. Article 450
• C. Article 517
• D. Article 725

Answer: (C)

The article for health care facilities is the one to consult. Hospitals and clinics have unique electrical needs to keep patients safe and critical equipment powered reliably, so this article spells out how power is distributed to patient-care areas, how essential and standby systems are designed and protected, and how life-safety considerations drive circuit design, labeling, and equipment requirements. It covers things like uninterrupted power for life-support devices and nurse call systems, and coordinates with emergency power considerations to ensure reliability in healthcare environments. While other articles address general wiring or specific systems, the health care facilities article directly targets the conditions and protections needed in hospitals and clinics.
