Does the NEC define "same electrical characteristics"? Would parallel conductors runs in two different size raceways (3.5" & 4") be of the same characteristics if they're both EMT?
310.10(I)(3) Separate Cables or Raceways. 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.
