What year was redundant ground required in hospitals?
(OP)
I am working in an old hospital facility and was wondering what year was the redundant ground required by the NEC?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: What year was redundant ground required in hospitals?
Please clarify -- the word "redundant" does not appear in the current edition of the NEC at all. Give us a section and verse, or a good physical description of what you're interested in...
Good on ya,

I don't know when it started, I can only tell you that it was at least before the mid 1970's as that is when I first got into health care work.
I worked on a local facility where our company had done a remodel project in the late sixties, and found areas with out it, but is was not clear if that was an existing condition when the work was done. The hospital had been built post world war two, so it wasn't required apparently before 1950-ish.
Hope that helps.

Thanks for finding that! I searched the pdf earlier and it didn't come up for some reason...
I can attest, like EEJaime, that it was before the 1970s. Can't say when though.
Good on y'all,

Redundant may be the wrong wording but it would be additional to the to the metal raceway system being a ground path.
Thanks guys!
