Hospital grade means that the product’s assembly or outlet meets the requirements for a “Hospital Grade” plug or receptacle. There are certain criteria that must be met in order to wear this moniker, but the key features include:
A slightly longer ground blade so that it stays engaged with the ground circuit until the power blades are completely disengaged.
Strength requirements for the strain relief and connections of the conductors to the blade terminals themselves.
The cable needs to meet certain minimum UL standards.
The blades must fit into the receptacle and hold with a certain degree of force
“Hospital Grade “ plugs and receptacles will have a Green dot affixed to the face to indicate that rating.
