The amount of work someone will go through to do something the wrong way never ceases to amase me.

We have a 200a service on a milk container company(DIY job)that use 2" pipe with the same setup. I look at it and wonder how the even got the wires in it. Probably pussed them in as the went along.

At least it's protected from physical damage to the extreme

Unless they killed it when the pushed/pulled/threaded it in!

Must have been one of those plumtricians, or elecumbers.

Although those are probably plumbing fittings, they look like electrical ELF fittings.

UF is considered its own raceway, isn't it? AFAIK, there's no restriction in what you can do to cover a raceway, so long as the pull boxes, etc, are exposed. Wouldn't this be acceptable, if perhaps not the easiest way to get it done?

The fittings in the pic appear to be plumbing items, as are the nipples. Therefore, unlisted items are being used for an electrical install.

No sense beating a dead horse; non-compliant installation.

I agree with HotLine1 that looks like galvanized pipe fittings.
