Re: hospital grade receps
Nvcape, many of the hospitals we work in use HG receptacles exclusively, even in maitenance areas, coffee pots, or exterior areas.
When HG is purchased in quantities of a few hundred to 1000 there is very little difference in price between Industrial grade, and it is one less item the facility has to stock.
Yes the configurations are the same although as you state there is different performance standards.
There is a HG twist lock device also.
Here is a 15 amp HG male cord cap.
