Feeder with no L-N loads & 215.2(A)(2)

[tortuga]

Greetings group
I am looking at upsizing a existing feeder, for adding a new load,
and I have an EMT existing pipe run.
The panel only feeds 240V loads, plus the load I am adding is only 240V.
(There is lighting panel right next to this panel that has a neutral.)
I don't usually like to stuff conduits to their max but this might save the customer some money.
If I have only 3 conductors in the pipe I could in theory get away with it and be under max fill.
The pipe is currently the EGC, and there is a neutral bus in the panel with nothing connected.
That 3rd wire would be better used as an redundant EGC.
I am probably going to solve this another way by relocating some equipment, but
It all got me wondering is a grounded conductor even required in a feeder?

I am thinking yes per 215.2(A)(2),
Thoughts opinions?

There is no requirement to run a grounded conductor in a feeder. Think about it, why would there be?

Absolutely compliant. I educated an inspector about this when I added a feeder and panel to a house for a tankless water heater. I used only SE cable, using the bare conductor as the EGC, and removed the neutral bar.

Thank you gentleman!

Curious as to why you removed the neutral bar?

To make it more obvious that there is no neutral, and only the EGC bar is available.

I used eight of twelve spaces in a 200a ML panel. Someone might try to add loads.

You're making it too easy on those who don't know any better Larry,,,,,

Yeah, well I have seen it where people have added to that equipment bar for 120v circuits. So Larry did a smart thing. I would also label the panel as 240V only

That's just another cautionary measure taken to make it easier on those who don't know any better.
