This used to be allowed by the NEC. How old is the installation?
Back in the late 80s, I was selling a customized transformer that had an attached secondary side disconnect and was painted white to match the ceiling space.

Brand new install.

Since it would take some sort of lift or scaffold to access the transformer it makes sense to locate the disconnecting means close to it. The disconnect is only for servicing the equipment, it is not for emergency shut off.

The transformer is fed off the buss plug above it so like this... bus plug is 37ft, x former is 30ft, then down to main breaker panel

Sounds similar to a good number of industrial facilities I worked in. Many items including transformers were locate high with disconnecting means located the same.

There's a video somewhere showing a couple of guys climbing a 1,768' tower and I seem to remember somewhere near the top they pass by a disconnect. I would hate to get up to 1,700 feet and have to go back down to turn off a disconnect.

Here's the video, the disconnect shows up at 2:18. I'm not sure now if it is a disconnect.

Just about everyone Home Depot I've been in has the transformers mounted near the ceiling with the disconnect attached to the side of it.

See 404.8(A)(2).

Watching that video made my liver quiver, and a 100% pucker factor!!!

And even though they got to ride 1600' the last 178' would be equivalent of climbing almost 18 floors

And me relieving myself at all 178'!

I know the feeling. I used to climb a ship mast that was 45' straight up, after the initial climb of 90' above the water thru the exhaust stack (so loud that it still hurt with foam ear plugs and mickey mouse ears. It's amazing how much more difficult it is climbing truly vertical ladders versus inclined ladders or wood poles. It is a super heavy duty arm workout. I'm sure those were the muscles he was resting when he stopped.
