Disconnect not 3R rated Greenfield not acceptable in wet location. Receptacle below disconnect not wet location type, no cover. Panel on left appears to have pipe plug installed in top hub, rather than proper closeoff plate.
Well, the greenfield might be acceptable if THWN conductors are used, AND if arranged in such a way as to prevent water entry into enclosures. I personally like to avoid installations that require a "judgement call" on the part of the AHJ, and just use sealtite outdoors.
There was nothing said about lack of access to the opposite side of the wall. Properly securing stuff would be pretty difficult then. MAYBE toggle bolts might have a chance, but I wouldn't really trust them.
Life is seldom cut & dry. I posted this pic here, rather than in "violations,' as it brings up so many things we can discuss!
For example, I personally would not use Greenfield in this application ... but, the NEC does not clearly say "no."
For example ... that pipe plug ... I've never seen an "electrical" one, and I've encountered a few such cans that did not use common plates .... and the maker has long since gone away. Otherwise, several makes of these boxes require you to have access to the inside to attach a blank plate. Personally, I'd just as soon folks keep their mitts out of such boxes ... so I'd just as soon see them use a plug, than leave it open.
This is the same building as the where the single phase device was being used to supply a 3 phase welder,if you saw inside the switch you would really have a fit w/ all the double lugging and the paper wasp who has made its home inside.
Note to John, that switch can be locked out with no problems.
