I was working at a new hospital where the inspector tagged the speakers because they were not UL listed (not my job).
I would
assume that since the inspector approves a job and his name is on the line they might look closer on some job site then others?
A new Hospital might get more scrutiny then a Ma n' Pa store in the 'hood.
So, an unapproved cable could easily be installed where a permit was not pulled.
Also, UL image can easily be downloaded and attached to anything:
Interesting read that puts it bluntly:
