Hmmmm,
If the cables were made buy a recognized cable vendor and had UL
recognition postage stamp on the box or individually tagged you
shouldn't have had a problem, especially if your drawings showed the
correct materials. Sometimes UL inspectors have to be guided into
following their own procedures. You can always call the district office
and talk to the FUS people in the controlling office for clarification,
make it a conference call with the local inspector at your side. You'll
both get a better understanding of the concerns.

Subject: RE: Wire Markings Mandatory?
Jim -
Yes, that's pretty much how respooling works.
The most odd aspect was that this was wiring already in a wiring
harness,
taken from a box with the appropriate wiring harness labeling.
The FUS Rep
wanted to see our drawings to verify the design of the harness,
which is
normal, but specifically wanted to verify the type of wire used.
For as
much as drawings are all they have to work with (if they ignore
surface
markings), this is at least another level removed from the
actual harness
build. Ah, well, there were no problems after the drawing
review, so I have
no reason to complain. It just seems that trusting the drawing
and not
trusting the surface markings on the wire are somewhat
contradictory.
