Dedicated space above a fused disconnect

Los Angeles Dept. of Bldg and Safety. Ugh

My inspector is calling me on disconnects in a mechanical room.
I have 4 fused disconnects in a mechanical room that meet the requirements for working clearance. 30 x 36 x 8' in front of the disconnect. He called me on the vacuum line and the compressed air line above and below, but behind the opening of my discos. I was under the impression that a disconnect does not fall under this code.

I don't see disconnect switches on the list so you're correct.

I believe that the reason for including only the four items listed in that code article is that they have the possibility of having additional circuits added at a future date. Leaving space above (and below) them allows for the future installation of conduits. Once a disconnect is installed (or for that matter any other electrical component not among the list of four), there will never be a need for future conduits.

I have no basis in fact for this belief, but it makes good sense to me.

I was thinking this exact thing

I wouldn't say never, but they generally would be less prone to adding something new to than the four items that are mentioned.
