If it is planned to install a transformer in a basement of a historical building (under consideration), what are the specific codes requirements as per NEC needs to be fulfilled?
Thank you very much for your response, the transformer will be 1000KVA, 3 Phase, 60 Hz, 13.8/400 V Dry type.If it is planned to install a transformer in a basement of a historical building (under consideration), what are the specific codes requirements as per NEC needs to be fulfilled?

who uses 400V/60 Hz? it is not a NEC std voltage.
To address "noise" noise must be defined in comparison to what? In a quiet environment an it that makes any noise at all is often considered to be noisy. The is similar to heat. When you expect an item to be cool to the touch is often said to be hot if it feel warm.An additional consideration is NOISE! Dry types are notoriously noisy and a museum is typically a quiet place.
And, I will echo the flood issus. Think of NYC, or anywhere else, and flooded basements. Even a serious water leak can mess things up!
I have worked several projects where chillers, generators, etc. have either been moved out of the basement or raised up higher.
Dependidng on the local grade, distance above sea level/storm surge,x year flood plane, etc. simply putting major equipment in the basement may no longer an option.
