Multiple sets of cables

[FaradayFF]

Hi,

I need to run multiple sets of 350s for a 3 phase, 480V Delta system. Should I run multiples of the same phase conductors in one conduit, or one of each phase per conduit.
I see the second as being a better approach, since the magnetic field would be more balanced if I had A,B,C conductors per conduit.
Regards,
EE

A-B-C in each conduit.

300.3
(B) Conductors of the Same Circuit. All conductors of the
same circuit and, where used, the grounded conductor and all
equipment grounding conductors and bonding conductors
shall be contained within the same raceway, auxiliary gutter,
cable tray, cablebus assembly, trench, cable, or cord, unless
otherwise permitted in accordance with 300.3(B)(1)through
(B)(4).

A-B-C in each conduit.

Especially with metallic raceways and enclosures.

This symmetrical arrangement makes sense. However, I can see some challenges with terminating cables to the breaker, since there would be cables crossing over where they come out from parallel conduits and routed to the respective breaker lugs. I guess that is not a huge deal.
