A quick, practical guide to hospital-grade connectors (the green dot mark), common NEMA and IEC types used on medical equipment, and the key compliance ideas to keep in mind.
In North American healthcare settings, hospital-grade attachment plugs, connectors, and receptacles are designed and tested for enhanced performance and safety in patient-care areas. You'll often see the green dot identification on these devices.
Familiar straight-blade connectors in hospital-grade versions for patient-care areas, available in 15A and 20A ratings.
Widely used on medical devices and power supplies; cords terminate to hospital-grade plugs on the wall side.
| Family | Typical Ratings | Where It's Used | Notes |
|---|---|---|---|
| NEMA 5-15P / 5-20P (HG) | 125V, 15A / 20A | Wall-to-device cords in patient-care areas | Green-dot identification on hospital-grade devices |
| IEC 60320 C13/C14 | 10A—15A class (device-side), region dependent | Monitors, pumps, IT/biomed gear | Often paired with HG wall-side plug |
| IEC 60320 C19/C20 | High-draw devices (e.g., 16A—20A class) | Servers, imaging peripherals, larger PSUs | Locking options available |
Always follow equipment nameplate ratings and applicable codes for your jurisdiction/facility.
It's an identification mark used on hospital-grade devices indicating they are designed and tested for use in patient-care areas.
In patient-care areas, many facilities and codes require hospital-grade devices. Always follow local requirements and your facility's policy.
Hospital-grade receptacles and plugs are built to stricter standards than general-use devices. They feature enhanced grounding, durability, and retention force to ensure reliable connections in critical environments. These safeguards help protect patients, staff, and sensitive medical equipment from electrical failures.
