We have followed development of the technical standards that govern the success of these “installations” since 1993; sometimes nudging technical committees — NFPA, IEEE, ASHRAE, BICSI, Uptime Institute, TIOA, UL among others.  From a codes and standards standpoint the topic improvises daily. Today we review open public consultations even though we know, at this pace, whatever standard stabilizes will soon be replaced. We can also poke at the Draft 2028 National Electrical Safety Code.
