CABLE VS. CONDUIT TO CONNECT MOTOR

[polareng]

I need to connect a 10HP, 3ph motor to contoller box. Do I have to use conduit or can I use cable? The run is less than 10ft. Am I bound by NEC 400.7 Uses Permitted? because it is not specifically Not Permitted per 400.8. I just find it hard to believe that this would not be allowed.

Agreed!

I would just say that transitioning from conduit to cable can be a bit of a pain because you have to provide a junction box to make the extra connections verses transitioning to liquid-tite and just pulling the wires straight through to the motor/etc.

UL listed shielded motor lead cable for drive-motor leads is available from Pirelli, Okonite, and recently, Belden.

I believe that each is listed for open (non-conduit) installation under controlled conditions.
