Which feature distinguishes a hospital-grade receptacle from a standard receptacle?

• A. Red dot
• B. Blue ring
• C. Green dot
• D. Yellow label

Answer: (C)

Hospital-grade receptacles are identified by a green dot, which signals they meet stricter safety and durability standards for medical environments. That green marking indicates features like sturdier construction, reliable grounding, and components built to withstand frequent use, making them appropriate for patient-care areas. Other color markings aren’t standard indicators of hospital-grade quality, so they don’t convey the same level of compliance.
