There is no exception.
When installing a top fed panel as a bottom fed I have had to remove the main and rotate it 180 degrees.

Ok thank you. I just thought I was missing something.

As Augie stated typically with those breakers you can reverse the bus connections and the terminals. While very neat that thing is a bit of a mess. They never should have flipped it in the first place because the feed is one top. Also why mount the panel next to it upside down also and then run the conductors all the way around the panel?

It’s something I see often on line. I often see this posted also.

What if there is a junction box on the backside of the wall?
Good thought I but I THINK still no good. It seems like this gets passed often. Not sure the hazzard it creates.

If there were a junction box on the back side of the wall with the two nipples into the panel it could be code compliant. NM cable is permitted in a raceway.
