hospital grade or commercial grade receptacles ?

Very eloquent, Albert. Very eloquent.

It just strikes me that someone who grows up near the ocean where the water looks green may never see the water as blue even when they are standing next to the bluest ocean in the world.

Tvad, what color is love?

Obviously it's red. Except in Hawaii, where it's orange.

...and Greece, where it's blue.

Why do you ask?

An update to my set-up; I had to change the electrical cable from a two wire (12/2) to a three wire (12/3) to
facilitate the correct installation of the isolated ground system. This was needed even with use of plastic boxes in the wall for the receptacles. I would also like to mention that a seperate isolated ground bar (plastic) is required in the electrical panel, hooked-up to its own ground rod. This made the system totally seperate from the rest of the house's system. Or so I have been told .
Just as a hedge against obsoletion, I also changed from 12 guage cable to 10 guage cable. So now I am running 10/3
with ground from the breaker box to the outlets. Two dedicated runs, each operating two H.S. grade isolated ground duplex 20A. receptacles. The change in cable necessitated an expenditure almost 4 fold, from about $27.00
to just over $110.00 ! I was actually able to purchase a roll 250ft. long for about the same price as having two 60
ft. pieces cut from the spool at Home Depot ! Exactly the same wire from the same manufacturer. Make sense ?
It is supposed to be hooked-up next tuesday.
Again, thank you to all who contributed information to my cause. This is a great forum !
