For those of you doing things like specifying UPSes, wiring racks
(and EPOs), etc.
I've just finished reading over the revised IEEE Emerald Book (IEEE
Std 1100-2005) and it is definitely the reference book you need. All
the stuff you've tried to discern by reading marketing white papers
from APC or Liebert is in there, along with comparative analysis of
various approaches, etc. What really differentiates this version
from the previous ones is a lot of attention to things like dual
power to racks, cluster computer issues. A whole chapter:
Telecommunications, Information Technology, and Distributed Computing
The actual document title is:
IEEE Recommended Practice for
Powering and Grounding Electronic Equipment
$140 in softcover.
