We have to install a 100A, 480VAC, non-fused disconnect switch in a boiler room for a new Air compressor. Can somebody assists the article in the NEC that defines the location of the disconnect switch...lke how far from a water source (wawter hose with a on/off valve)?

It is just a regular motor disconnect. No special requirements because it is in a boiler room or for a compressor. I don't recall there being any requirements about distance from a water source either.

take a look at article 430 starting at 430.101.
