Some of my comments,the 1st thing that caught my eye was, that PVC TA on steel pipe,and 2nd was the cheesy way of "supporting" the bundle of NM cables,thought it would make a good photo.
Another comment made here was about the bundling of the cables,with the design of those panels,1/2 being used for metering,that does not leave much space for KOs (approx. 3 1/2" x7")so, its a common practice to bundle it that way, although as long as inspectors allow it it will continue.
