What is this 6 CCC phrase? You can run 9 CCC with NM, just like EMT.

There are times when to pick a fight, and times to go on. If it’s going to cost a lot, that’s the time to fight, but if it’s a simple change (note I did not say “fix”) do it and go on. I had a state inspector want the bond put on the load side of a ground fault service rated transfer switch. Could not get it through his head why it would defeat the ground fault protection. Went ahead and done it to pass, then put it back where it was supposed to be after he left.

Some just go overboard. I get if something doesn't pass legitimately but some things are just for their little foot syndrome

Unless I'm rather mistaken, the UL listing (E19459, yes, I looked it up) only applies when the strut is used as a raceway. Not a raceway? No listing needed or applies.
Years ago, we had two inspectors. One had the west side of town, the other the east. Both had their own set of rules, and many were contradictory. So you needed to know who was going to be eyeballing your work. Worked out fine......... until one went on vacation and the other showed up to cover for him.
That was a nightmare.

There are a fair number of long time electricians who believe things are code that aren't and vice versa.
As long as it does not affect me all that much I just let it pass.

There's a fair number of long-time electricians who never bother to own a code book, let alone actually read it.

Here in NJ that wouldn't fly. The inspector is required, by DCA regulation, to quote the violation chapter and verse.Hate it when inspectors say that. Sorry, you are doomed. Good look finding unistrut instructions that tell you what you CAN do with it.

That is about the only possible thing that could be in violation IMO, many places don't reject that though.
I've seen many those mounting ears let go if they were used to mount such a box. So what if a little bit of water finds it's way around mounting screws through the back. If you have raceway entering from above you are getting condensation in there anyway, better make sure to drill a weep hole in the bottom. Almost every bell box I encounter that has been installed at least a couple years with no weep hole has bottom device screw rusted in place, if there was a weep hole it often still looks like new.

I drill two 1/8" holes at the lowest point of boxes, LBs, etc.

The question to ask is did this alter the unistrut in a manner not consistent to its listing? We are limited in using any material per how it is listed.

Lumber and plywood are listed. Does anyone worry about drilling and tapping them.

Where is it that one would find the requirement that everything used in an electrical installation be listed? Large portions of the code only require that certain items be identified or approved. Even larger still are the number of items that we use all the time that are not mentioned in the code at all.

If a plain, suitable piece of steel bar or channel could be used as support in such a manner (and I'm saying it can), then why can't a piece of steel that happens to come with regularly-spaced punched holes and a pair of rolled edges be so used?

Installed boxes many times on strut, the problem encountered is applying the 3 ft strapping rule (emt) . or usually one can mount a box supported by a ceiling anchored rod . Although a spec usually supersedes a common practice. a spec can request gold plated conductors even though its not code.

I had a inspector ding me for using drywall screws for mounting boxes on plywood. It was a city inspector do I asked to appeal it. There was no appeal process but they decided to pass it just this one time. Giving power to someone that wants power can be a bad thing
I was a State Electrical Inspector in Idaho and we had to provide a NEC reference for any violation see cited.

In many jurisdictions it's up to the inspector to determine if the screws are acceptable to support the box. Anyone who rejects a box screwed to plywood with a Sheetrock screw is an idiot.
