The introduction of new Article 409 in the 2005 NEC may be the source of this assertion. Do a search on "409" and read the threads generated in the last 60 days or so to get a feel of the consensus of this forum.

Re: "UL Approved"
UL does not approve, they list. The AHJ approves, but does not list.

Re: "UL Approved"
Here in Ohio on commercial projects including gasoline stations we build custom control panels and the local inspector examines them for compliance with grounding, wire bending space, and so forth.
There is also an earlier NEC article on industrial machinery. I have done a lot of work on industrial machinery and nowhere have I encountered a requirement in Ohio Building Code that a control panel has to be UL listed instead of inspected by the local inspector.
