NEC or UL which standard rules?

"In this week's episode, King James Stallcup and myself delve into the critical role of listed and labeled equipment in electrical installations. We explore how the Authority Having Jurisdiction (AHJ) relies on these listings for approval, treating the NEC as a guideline rather than a strict rulebook. We also discuss how the Code Making Panels craft the NEC references that the AHJ interprets, with a particular focus on the implications of 110.3(B) listed and labeled instructions."
