ECN Forum Forums General Topics of the Trade General Discussion Area how do you do that iwire?

In this thread https://www.electrical-contractor.net/ubb/Forum1/HTML/006748.html you gave a white book reference.

Is that a service you have to pay for or is that offered for free on UL website?

I spend too much time on Fri trying to get clarification on a puck light listing and I'm still not satisfied.

thanks
