If you were talking about a UL1950 product, there is an inference in the UL1950 second edition application guidelines that you would need to use Recognized Component wiring. "Application Guideline - Primary wiring or wiring that is used as basic, supplementary, double or reinforced insulation shall be Recognized Component - AWM". "Rationale - If wiring is used as a level of protection against electric shock it shall be reliable and requiring the use of Recognized Component - AWM is valid. On the other hand, wiring that is used as operational insulation is not required to have the same level of reliability (because UL1950 permits other options to evaluate spacings) and the use of non Recognized wiring is acceptable if flammability concerns are addressed."
