Life Support Branch
Life Support Branch
(OP)
In numerous military hospitals we do work in, we have encountered another branch of the essential electrical system. In addition to the usual life safety, critical & equipment branches, we find a "Life Support" branch complete with its own ATS. It often feeds isolation panelboards but not always. I have not encountered this branch in any civilian hospitals. I am guessing this was a Dept. of Defense requirement many years ago but nobody at these facilities seems to know. Does anybody know where and when this started and what it was supposed to feed?
