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?

Hi Jae48, yes I do have one dedicated line coming from the main circuit breaker box at present. Right now it only contains just a consumer grade receptacle - meaning one dual outlet. I have an Arrow Hart 8200 on the way to me, which I've read some good things about, and so that will replace the outlet that's there.

Although I've been an Audiogon member for awhile, I've only recently stumbled upon the whole clean power/dedicated line thingy, and as of right now cannot even tell you which components are plugged into the dedicated line. I figure when the AH8200 comes, I'll either 1) Run only the amp and pre-amp from the dedicated line and run the PC (which is my CD player) and everything else from a common house line, or 2) Do the "split everything off of one outlet" approach and see how that sounds.

In my case, "everything else" is a lot of audio recording gear as my main listening place is also my workplace, which is a recording studio. So I've often got at least a dozen things on at one time that never get shut off and remain on constantly: outboard effects processors, microphone preamps, mixing boards, power conditioners, etc.. I know that this is not the audiophile best case scenario, but I spend only enough time at home to sleep, and so my studio has become my listening room.

Cheers,
Ray
Jea48, I find it interesting to know that the "pull pressure" of hospital grade recepticles is tested for the hospital environment. I didn't know that and I work in a hospital. However, I'm sure our maintenance personnel are aware of that. One thing to note, at least in our hospital, is that the red recepticles are the only recepticles that are used for normal power and power from the back-up generators. The red recepticles are used for computers, ventilators, etc. Also, it takes between 10 to 15 seconds for the generators to come on line, so there is a slight interruption in power, except for anything also plugged into a battery supply. Our ventilators have a builtin backup battery supply of about 30 minutes. Thanks for the education!
Facts:
Hospital grade plugs provide more robust grounding than a regular plug. They are built to a better quality. Grounding and isolation transformers are very important to medical equipment. The 15 and 20 amp (three prong plugs) are not suitable for use around flammable materials. There are explosion proof 15 and 20 amp hospital grade plugs that look totally different than a regular plug. You have to insert these turn them a quarter of a turn. These are usually found in older operating rooms. No one at a hospital checks the force required to remove a plug.
(My boss is going to laugh when he hears that.)

I am a biomed tech and I work on and test medical equipment.
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!
