Seeing only the cardboard as a problem is a little 'shortsighted'.
How about the panel mounted on a cabinet. How about the conductors not supported to the enclosured. How about the bundling. How about taped breakers, how about the transformer installed on a combustible surface (construction paper), how about the support of conductors supplying the transformer, how about working clearance, how about the panel labeling not being complete, how about the water bottle sitting on top of the cabinet above the panel and transformer, how about the screws missing on the panel cover, how about the open trough covers, how about the use of cardboard to protect the NM cable entering the panel enclosure.
As I am not there, I would be suspect from what I can see about the: grounding of the transformer, and the panel it self. The wiring in the ceiling shows the lack of concern for one of the most important aspects of our industry - PRIDE!!!
