Installation of receptacles on I.T. racks

[ron pfeiffer]

Looking for article or info on wiring methods for installing 120v 20amp devices in 1900 boxes on to the racks that are bolted to the floor and fed from above a drop ceiling. Are there specific piping or attaching to these racks that I need to attend too.

I do not think this will be specifically addressed in NEC. TIA may have something to say about it if it applies. We typically do 1 of 2 methods.

Attach to the center of the rack or the horizontal ladder rack on top or attach to the vertical management adjacent to the rack.

If no special codes, you can attach to the rack on the inside, just don't block the equipment mounting screw holes

I did the installation like the diagram shows. An engineer from Motorola stated to the department head where this is located that the installation was not up to code, I suspect 2014 but I can not find anything that would restrict me from 1/2" EMT from the ceiling directly into the 1900 box.

Must be one of those Telco specific codes that I am not familiar with. If you do not find your answer from someone here you might try this forum.

Not an NEC code, did the job specifications require you follow other standards or codes as well as the NEC?

What are you working on?

What are you working on?

Probably a job that requires R56 compliance.

That's what I'm wondering. When I saw the words Motorola Engineer I thought, poor fella.....
