Presuming you mean the "redundant grounding" requirement only applies to branch circuits (and not to feeders) I agree. Not many items in a general patient care area that need more then a 20 amp branch circuit, so no demand for more then 12 or 10 AWG, means it probably is not stocked. X ray, MRI equipment, etc. may be the exception but those are limited in comparison to how many other patient care rooms there are with only need for 20 amp max branch circuits.don't see it cataloged anywhere. since its primary use is for branch circuits I doubt you will find it larger than 10.
