If we want to run (3) sets of paralleing wires (4W+G+IG) in (3) conduits from panel A to panel B. Can we run only one isolated ground wire in one conduit and ignore the other two? Thanks!

Where run in separate cables or raceways, the cables or raceways with conductors shall have the same number of conductors and shall have the same electrical characteristics. Conductors of one phase, polarity, neutral, grounded circuit conductor, or equipment grounding conductor shall not be required to have the same physical characteristics as those of another phase, polarity, neutral, grounded circuit conductor, or equipment grounding conductor to achieve balance.
