UL 891 Supplement B

[Barry1952]

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?

Hi Barry,

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!

Forgot to mention -- I looked through the proposals for the current UL 891 standard, it's possible that Supplement B was deleted in 2004.

UL 891 versions before 2004 are not online.

Good on ya,

Thanks for your reply
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

Good job for straightening it out!
