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?

It means

1) more expensive
2) not always covered by insurance and
3)linked to fear

so you will be less likely to protest and just pay the extra money.

Nerspellsner, LOL, I never heard of that test, LOL.
You do know there is a device that plugs into the outlet and while extracting it, will give you the resistance to the pulling action in ounces...
