And this got passed an inspection!?!?!?

How many inspectors are familiar with camlocks?

Almost none.  They'd be more interested in the access lock out and wiring behind the Cams than the connector itself.  OTOH I think this inspector doesn't realize there is language about requiring non-exposed terminals on line-side connections...  With Cams, though, is the female terminal not exposed, or is it being "less exposed" than the male deemed sufficient?

So, this is the new power tie in at a local venue.  Yes, this is the SOURCE of power....

It's stupid, wrong, and dangerous, but pretty much every distro or dimmer rack I can remember using has ins and outs on it so I'm pretty sure this wouldn't slow things down much once the feeder got run the right way.

Not all that I have seen and you can't run the feeder the "right way" with this connector configuration unless you use turnarounds.
It's wrong, it's dangerous and it needs to be reported and changed!

For those who still do straight-through (non-reversed) neutral & ground only 3 turnarounds will be needed... ;)

Those of us who do non-reversed neutral and ground are the ones following code.

So Brian, has anyone come back at the venue to tell them of the issue and have the electrician come back to do the job correctly?

Those of us who do non-reversed neutral and ground are the ones following code.
So I'm certainly not an expert on the NEC. I was under the impression that code required a method to ensure that only 'qualified persons' would connect/disconnect single pole conductors (cams), and that some sort of mechanical system was required to prevent incorrect connections. The two accepted methods were either utilizing Posi-Locks (because you can't connect the hots until the GN were connected) or using RGN distros (since there was a physical dissimilarity that would prevent a screwup)

Can you elaborate as to why it's no longer acceptable under code to use reversed ground-neutral distros?

I'm  not sure what Craig will cite, but unless Code has changed you have the option of using any of 3 methods - physical interlock, polarized connectors (RNG) or labeling with access and connecting limited to competent personnel only.

Completely unrelated, but I know a guy locally who is color blind. He's not allowed to ever touch cams.
