What exactly does "Hospital Grade" mean?

I put a bunch of Porterports into my system and there was a very notable improvement. Of course, considering what came out of the walls in the way of really cheap recepticles, this was to be expected. Not an expensive upgrade.

Well worth it.

Like everything else in a hospital it probaly just means they charge 5 times what it is worth!

"Hospital Grade" takes the place of "Mil-Spec" now that the U.S. healthcare system has overtaken the Military with regards to power and waste.

I tried them all and I did not noticed any difference. I have a BAT VK-6200 and it works the same in a PS Audio Duplex receptacle as it does on a $0.49 Home Depot cheapie.

Switching to a duplex outlet without nickel plating on the internal brass components is not a bad thing. Using some contact cleaner with it is even better. My house, which is only a few years old has the newer, designer outlets and switches. These things are junk inside but cost more, go figure. I recommend the hospital grade outlet just for a tighter, more secure connection.
