When do you enforce NEC 645.10 ?

    There are several instances where IT equipment is installed in a room or closet. Whether you are still on the 2008 NEC, 2011 in which a lot of changes took place or the 2017 NEC, at what point do you start to consider compliance with 645.10 / 685 mandatory?

    This has been an area that I have struggled with due to language and practicality.

    What say thee?

    Honestly, never saw that. That being said, most of the stuff I have seen is plugged in......The HVAC one is interesting, but I am not really sure that the 2014 language gets you to an HVAC disco in the room....

    This made sense 50 years ago with mainframe computers. It might make sense for a server room, but the definition if "Information Technology Equipment" is so broad that it could apply to my desk computer, which would make my cubicle an "Information Technology Equipment Room".

    I think that is a bit extreme but I get your point. How about a server and IT room that is 8'x8' with its own HVAC and 3 bays of equipment with UPS integrated? Would that be a "no brainer" or would you have to think about it?
