Grouping 480 volt conductors emf

[dm9289]

I am putting 6-750KCM conductors in cable tray for 480 volt, 2 A-phase 2 B-phase 2 C-phase

When laid in the tray how should I group in order to avoid EMF problems

AA-BB-CC?

OR

ABC-ABC?

The closer the current carrying wires are, in particular the smaller the area that is needed to enclose each balanced group of current carrying conductors, the lower the radiated EMF will be.
So the answer is ABC, ABC. Or, when appropriate, ABCN, ABCN.
And it would be better to lay and tie each three phase group in a triangle rather than in a row flat on the bottom of the tray.

Thank you

Thank you

Thank you very much, particularly for the triangle hint. I had some related tray cable question today and got no replies at least I now know I am signed in properly.

Bundling them AA-BB-CC would violate 392.20(C), cause local heating, and negatively affect conductor balance.
