When 70E is referenced in the NEC I see informational notes in the code calling out the year by 70E-2015. I don’t see, however, the same version reference for UL standards. In Annex A there is a list of standards with notes saying these standards could change.
Is the most current version of a referenced UL assumed? Is this documented in the code somewhere?
Example: UL 1008 version 7 has some large changes for transfer switches. Do all manufacturers need to comply with the 7th edition or is it good enough that they are simply UL listed?
