I am not trying to be argumentative. I just would like to know if I am misinterpreting something or not referencing the right info. This is what I was referencing when I mentioned that the insulation has to be rated for the highest circuit voltage:
NFPA70 Article 300.3(c)(1) Conductors of Different Systems. (1) 1000 Volts, Nominal, or Less. Conductors of ac and dc circuits, rated 1000 volts, nominal, or less, shall be permitted to occupy the same equipment wiring enclosure, cable, or raceway. All conductors shall have an insulation rating equal to at least the maximum circuit voltage applied to any conductor within the enclosure, cable, or raceway. Secondary wiring to electric-discharge lamps of 1000 volts or less, if insulated for the secondary voltage involved, shall be permitted to occupy the same luminaire, sign, or outline lighting enclosure as the branch-circuit conductors
