So, I was starting a one hour electrical review course that's part of our on-line company training and they had a 10 question pre quiz. One of the questions was regarding the new UL holographic labels and asked whether an electrical inspector would fail an installation with equipment that had the old plain labels. As usual, I probably overthought it and marked that the old labels would be fine, thinking if you had old stock they wouldn't make you junk it just for the label. It was the only one I got wrong. So, old labels good or not?
 
How long have the new labels been available and what if I install a product that has old labels and has been on the shelf for some time?

There is an article in EC&M from October 1, 2008 announcing the new labels. But it was for only 32 categories of "common consumer product areas", so it doesn't sound like everything UL would require the labels. It looks like other categories were added over time, but I don't know if it's 100% by now.

My question is the same as yours; suppose you have 10 or even 15-year old stock, what then?

That's a stupid question. I hope it doesn't reflect the course itself. (n)

Sadly, it did. The "final exam", if you will, was a repeat of the pre-test. But, I don't get paid to assign the courses, I just have to complete them.
 
Many electrical products far exceed that label. Some marks are molded in. That would be like asking if a product has a CSA label is that an issue. In general as long as it’s not CE or MSHA you’re good to go. That sounds like typical UL political garbage.

I'm not sure about that. The course was written by a journeyman from FL "with over 20 years experience". Maybe he got burned in a big way on a job regarding the UL label. Anyway, it was supposed to be a 1 hour course, it barely made 45 minutes, including the pre- and post-tests. All the course content was presented like someone took random articles from the NEC, mixed them in a hat, and wrote the course in the order they were pulled. On one slide, it took me a short moment to realize that the "bounding jumper" was supposed to be "bonding jumper". There were a few others like that. I found it...underwhelming.
