Product details:

This hospital grade receptacle is designed to withstand the severe conditions of abuse that are unique to hospital environments. Built with nickel-plated bypass contacts that increase contact pressure and help lower operating temperature. The four-point grounding system provides redundant grounding for low resistance ground continuity, and thermoplastic polyester (RTP) back is tough and heat-resistant. To quality for the hospital grade designation and use of the green dot symbol, UL requires product performance to specific levels. These levels form an established baseline below which no manufacturer can fall and still carry a green dot.
