Cable Jacket = Raceway?
Could someone please offer some clarification of 725.55(A)? As it seems to read, LV and line conductors are prohibited from sharing the same raceway. But does the outer jacket of a multi-conductor cable constitute the cable's own raceway, insofar as of The Code is concerned? More to the point (and noise issues notwithstanding), can speaker wire, CAT-5, RG-6, etc., be installed in a common conduit with NM?
