It's been quite a while since I worked in the biz, but IIRC, UL is a NRTL,
"Nationally Recognized Testing Laboratory." They don't approve devices per se,
but rather certify a device passed statutory safety standard testing. A
certification only means samples and manufacturing process passed the specific
tests. Other NRTLs can do the same, and there are quite a few. A manufacturer
needs to have their products certified by an NRTL if fed, state, or local
regulations require it, or customers (often large entities) require it. At the
time I was in the biz, "harmonization" was going on, that was bringing all the
disparate standards of various entities into alignment. IDK what the current
situation is.
I'm sure there are more knowledgeable and current guys on this reflector.

Unfortunately,
the email footnotes don't include a link to the archive thread, and
there is no context, so I don't know to whom you reply...
but I am part of the thread, so I'll clarify for my part.
the loose connectors are UL listed. Two were loose, and 1 was incorrectly
installed. I actually saw a web page that showed //an incorrect installation//
as part of a "help page". I sent them a note, but didn't follow up.
Ah! Had not used nabble in the past, and I now see that this is in response to
Bob McGraw - K4TAX, but the context is not clear.
