hospital grade or commercial grade receptacles ?

Very eloquent, Albert. Very eloquent.

Tvad, what color is love?

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 !
