Just to expand on this, the NRTL has to test to the specific UL standard. However, if you look at the definition of "listed" in the NEC, it states "equipment, materials, or services included in a list published by an organization that is acceptable to the AHJ...). I have heard of some jurisdictions in CA that do not accept CSA, Tuv, ETL, etc and will only accept UL as a testing agency.
BTW it is possible to do field certification of equipment, although it's probably more cost effective to purchase new modules.
