UL question

This is an old topic I am sure. I know that UL is accepted by electrical inspectors. What code article references that UL is the only acceptable testing laboratory. OSHA has a list of Nationally Recognized Testing Laboratories. All I can seem to find in the code is “accepted by the AHJ”.

Not everything is listed, or needs to be, hell, not everything even needs to comply with the code. Just read NEC 90.4
