Are any of you using type S/O cable to supply fixed electric motors in an industrial setting? I believe that this is allowed under 400.7 Uses Permitted (7) Prevention of the transmission of noise or vibration.

We have several 25 to 125 HP motors that repeatedly rub through the conductor insulation in the flexible conduit near the motor. Am considering replacing the last few feet of conduit and wire to a Type S/O or perhaps even a type W flexible cable.
