I am working in a basement corridor and room beyond of a very old university. We have removed the existing surface mount sub-panels from the room per design and installed new flush mount panels into the corridor wall with the opening in the corridor. All branch will sub up and out into room. Panels are dedicated to each room. The corridor is only 9' floor to deck with the entire corridor spanned with wet and dry utilities a mere 7'8" AFF. Above and encroaching 4" into one side of my panel are some 3/4" copper chiller lines. These can't be seen from the front, but can be seen in the room. In your opinion, will the existing utilities in this corridor or chiller pipes pose a violation of working clearance. I tried to attach a photo but it was too large. Just picture a 4' corridor wall to wall with pipes at 7'8"

Have you considered that the corridor walls may need to be fire rated, making flush mounting a problem?
 
If you read the language and apply it exactly as written, flush panes are a violation. However, that is always overlooked as that is not the real intent. (the top plate of the wall is in the dedicated space) I have never seen 110.26(E) applied for flush mount equipment.

Thanks, I think it won't be an issue. This city tends to cater to this university.
