i meant a drilled hole, not punched for use for a UL clamp or UL fitting for termination.
sleeved sounds good, where is the sleeve in pic?
any wire "secured" can still be yanked if force is high enough.... in this case it was unsecured wired, etc.
I have drill bits that can drill same sized holes as holes made by some of my punches - my point was if field made holes are not allowed - we may as well throw away all our hole making equipment.
there is no sleeve in the pic, a sleeve may be seen as a good design option - but is not required.
It may or may not be secured, it definitely is not secured at or within (very) close distance of the enclosure. I've seen more cases where the entire disconnect or panel was damaged by something then just the ground wire got pulled. You can't put all what if's into code, if you did we would run RMC to everything, plus put everything into concrete vaults, and even then there may still be some what if's that were not quite covered. You can design to common conditions for the location though, and accidents will still happen at times.
I have no problem with the installation as pictured, have done hundreds of similar installations, and have never lost any sleep over any of them that I am aware of.
