I'm a fan of your site, and circulate many of your photos around the office.

Here is an installation in a parking area of a residential high-rise.

The transformer is certainly protected from mechanical damage, and the "sarcophagus" appears neatly constructed.

Other than the obvious code issues of clearance and access to equipment, dust, debris and garbage is accumulating in the well around the transformer.

Needless to say, this was done long after sparky had finished his work.

Looks like maybe the insurance carrier mandated full oil containment for all transformers--NO exceptions.

I was hoping for a couple of bollards. Someone must have had some concrete and a lot of spare time.

What a shame. The electrician did a nice install, then some moron does this to it. The concrete guys probably had a hard time making the forms with the big gray box in the way.

Looks like maybe labeled clearances on the drytype have been shot to hell, particularly if its a 150°C-rise unit. But then, who reads nameplates anymore? Oy.

Even if the transformer was strapped to the wall, well above/outside the NEC110 disconnect and panelboard space, the leftover working depth looks seriously constrained.
