ECN Forum Forums Code Related Discussion NEC & other Code issues Mixed cables and conductors in a raceway?

I’m wondering if 300.3[B] and 300.3[B],1 might apply if the conductors are all part of the same circuit, since both also state the same "cable or cord" as well.
Something else maybe, is that 334.15[B] is for exposed work, so not sure if this would preclude the NM from being run in a conduit that is concealed or partially concealed.
