This poses an interesting situation for inspectors. Do we violate the installation for not using the proper listed equipment for the enclosure, or do we say at least they separated the equipment grounds from the neutral so I am satisfied? This is a very typical installation I see almost everyday. This is clearly a violation of 110.3(B), but...
I will say this; I have seen large faults where the connection of the fittings and the screws were scortched - obviously not a good sign for the fault current path.

110.3(B) is the first thing that came to mind with me when I saw this also... The thing I mostly was concerned about was that the panel can is being used as the bonding means (No separate EGC coming in with the feeders via EMT). If it comes down to clearing a fault on the 60A 240V A/C circuit which is connected in this panel, will the buttonheads or wafer teks be reliable in doing so?
