UL 891 Supplement B
UL 891 Supplement B
(OP)
Please advise where one can get this? I seen it referenced by "asco1 (Electrical)" in another thread but when I search for it all I find is Supplement A?? Even when I go to the UL web site. Is there truly such a thing?





RE: UL 891 Supplement B
There is no Supplement B to UL 891 that I can find, and I have access to the full library.
If you're a UL customer, you should address this question to them. May have been from an older version of the standard? There is a customer service e-mail address available on UL's site, they're pretty good about answering them within one day.
Good luck!

UL 891 versions before 2004 are not online.

Yes, I did go to UL and after a couple of emails with them they finally led me to the fact that Supplement B is now actually Annex G of the UL 891.
It can be amazing as to how someone is to know some of this stuff at times. Clear as mud I'd say
