Can 1/C, 600V, THWN be routed through a manhole containing MV cables if the 1/C, 600 V, THWN is separated from the MV cables and securely fastened to racks, insulators, or other approved supports? Ref 300.3(C)(2)(d).
The paragraph of 300.3(C)(2) states the conductors having nonshielded insulation and operating at different voltage levels shall not occupy the same enclosure, cable or raceway. For the previous question, is a manhole considered an enclosure for considering whether 1/C, 600 V, THWN can be routed in the MV manhole?
How would you barrier off or route 1/C, 600 V, THWN between ducts in a MV manhole?
