An issue has risen regarding a cable routing between a multi-drive VFD and the motors. The cable itself is rated UL Reg AWM style 2570 connecting to a VFD drive enclosure (UL listed) via a UL listed cable tray from an AC motor (UL listed). The cabling is expose (open - not in cable tray) when arriving to the JB at the motor for a few feet. These cables have ~ 55.6mm outside diameter and compose of 3X185/KCMIL350 + 3G35/AWG2.
There are indications that this cable is not meeting NEC code because of the exposed part of the cable as it arrives to the JB at the motor is not inside the UL listed cable tray. I can not find this requirement in the NEC 2005 or NFPA 79, easily. Any ideas, options or recourse? Do I need an UL inspector to "Bless it" or cover the expose part with flexible conduit that is UL listed? Thanks.
