If you had pendant drops, for receptacles, on two different circuits, would it be good, or permissible, to connect the cord drop to a box, then nipple over to another box? This would be a MWBC. The boxes would be Bell boxes with hubs. Would the 2nd box be considered supported with just a PVC nipple from the box with the cord? Strain reliefs would be used on the drop.
 
Then I would agree with buck (post #$2) , the 2nd box would need to be supportd by other than a nipple 314.23(F)
 
I take it the issue is the language 314.23 language requiring a conduit supported box to be "supported by two or more conduits threaded wrenchtight into the enclosure or hubs."

In which case I see there are 2 gang weather proof boxes available with either one hub per side, two hubs per side, and even one hub on one side and two hubs on the other. So you could two boxes, stacked vertically, with one top hub on the top box for the centered cord grip, and with two hubs on the sides facing each other. Then you could use two conduits nipples to connect the boxes. Only one would be used for the wiring, the other would just be for support.

Cheers, Wayne
 
I hate seeing bell boxes on cord pendants. Besides any legalities, they can crack or break when dropped or something hits them. You could use FS boxes but those are heavy. Fortunately industry solved this 30+ years ago with the rubber pendant boxes. Ericson makes a version that is a 4 gang (double sided 2 gang) perhaps that would work for your application?

I forgot about them but used them in the past on industrial jobs. Great solution albeit a bit pricy

These would be 6'-7' off the floor with no traffic. There will be 20 of these drops, and at over $100 ea for those rubber boxes, I doubt the customer would go for that.

Yeah, they're a pain cost wise. No reason they should be that much, its like there's collusion on pricing between the 5? companies that make them. We use these extensively in the entertainment industry, there are a couple companies that have spent the money on tooling to make their own boxes but they only use them on their own products and don't sell them.

Just reduce your exorbitant labor rate a bit to offset the added material cost :) :) :)

You're joking right? These are a specialty item commanding a higher labor rate due to non standard assembly, not to mention having to source and order them.

Yes. I am joking (hint: 3 smiley faces after my post). I know Bill and consider him a friend despite his rates,.
