What exactly does "Hospital Grade" mean?


I plan on changing my outlets since it seems like a cheap enough tweak and most here on the forum agree that it makes a difference. But what actually IS the physical difference between hospital grade and non-hospital grade outlets?

Sorry, not true....If a plug is pulled from an outlet and there is a connected load, current flowing, there will indeed be a spark. Hospital grade receptacle or not.

Hospital grade sockets perform this function well because they're designed for health care environment where uninterrupted power is important.

An uninterrupted power in the hospitals suppose to be before it reaches a recepticle. In case of a blackout every hospital has an alternate power generator.
One of the tests is the drop test. It goes something like this. The outlet is mounted 50 inches from the floor. A 3 foot cord with a hospital grade male cord cap and a 8 pound weight at the end of the cord is plugged into the hospital grade outlet. The weight is dropped straight down at the outlet height. The cord must stay plugged in and no damage done to the outlet to pass the test for hospital grade.
