The difference between Listing and Recognition IMO, is with Listing UL has a specific test for that component or assembly. With Recognition, no Standard test is available or the component or assembly was not tested to that UL standard.
Power circuits within the Industrial Controlled must be 90 degree C wire. Control wiring must be 60 C degrees.
The proper color of the wire is required, depending on task, and proper gauge with circular millage is required Proper terminations are required, but I could not find within UL508A that the wire has to be UL Listed.
Does this help?
If you could be more specific, perhaps a more specific answer could be given.
