At a manufacturing plant where there are vertical conduit drops 30' long with no supports. How can they get away with that?

Or perhaps it is an inspector with a brain, who looked at the installation and recognized that 20 feet is arbitrary and dropping a piece of 1/4" threaded rod with a mini on the end would add exactly zero to the integrity of the system. I hve met inspectors on both sides of the spectrum.

I'm not sure how you get away with taking a picture inside a plant and posting it on the web.

Most manufacturing facilities frown on that type of thing.

This particular plant does 10 hours a day don't think there any big trade secrets here

Just curious, how high is the bus duct mounted? We just mounted some at 24 feet and had to buy a telescoping hot stick because the sticks provided by Square D only come in length up to I think 18'

I don't think conduit is really "supported" if the "support" is weaker/more flexible than the conduit. Beat the assembly with a sledge hammer, and those threaded rods will break long before the conduit.
 
The place looks pretty sharp to me.

I don't think the got away with anything worth discussing.

You are welcome to think that, but cite a code section. A ceiling wire is far more flexible than a conduit and the code specifically allows them when installed independent of the ceiling grid.
 
40' ceilings

40' ceilings

We have 40' ceilings but we ran our strut racks at 23' so the top of any machine is no more than 19' unsupported.

As for how they get away with it, no inspections after power panels in allot of large plants that are self insured.
