Data Center branch circuit removal

[Zipper0326]

We are removing a bunch of equipment from our Data Center, and I could swear I recall reading years ago about a requirement to remove unused branch circuits from under the floors. This thing is 40 years old and has flex everywhere, and bean counters will do the least possible.

Thanks for any assistance.

With the exception of LV cables covered in chapters 6, 7, and 8 there is 372.13 and 374.7 that I'm aware of, but they do not actually mandate removal of the branch circuits.

You may have been thinking of underfloor raceways/duct.

Data centers are always changing. I always had "spare" circuits under the floor for a "new rack is showing up next week" contingency.

l6-30 wips abound. it seems most equipment evolved to that.

Not the same as underfloor raceway. See 390.8 in 2017 NEC for abandoned outlets.

It is a good idea, but not required by code.
Many times we can get them removed to maintain airflow

Is this an Art 645 application? I reviewed that article, removal only required for abandoned low voltage cables not tagged for future use, which similar to other articles.
