How many of those made-somewhere-in-China gizmos have forged UL seals
on them? Or does UL have an enforcement arm that precludes such
stuff from happening?
("line", not "mains" - if you are
talking US electrospeak).
I've seen both in US literature. "Mains" seems to be more common than
it used to be (which was not at all).
Oddly, OSHA's electric power glossary contains neither term:

"120v distribution power?"
I like "mains" from a gloablspeak perspective, but I'm listening to
the Beeb now...
