Which NEC article covers health care facilities electrical systems?

• A. Article 800
• B. Article 600
• C. Article 701
• D. Article 517

Answer: (D)

Health care facilities require specialized electrical systems governed by NEC Article 517. It covers the installation specifics for hospitals and similar facilities, including requirements for patient-care areas, life-safety considerations, and the essential electrical system that must stay powered during outages. It details how normal, emergency, and standby power are coordinated to ensure critical medical equipment and life-safety systems remain active. The other articles focus on different areas—communications systems, electrical signs, and legally required standby systems in other occupancies—so they don’t address the comprehensive rules for health care electrical installations.
