UL Listing

Hi Im working on some hardware designs and was asked about UL listing. I have gotten UL listing before for LED lighting products I have designed. It was a long process and was curious if anyone had any good tips or suggestions for finding the correct standard.

I find the UL site to be a bit of a pain to navigate. I have an electrical connector I designed (riveting stuff!). Its based on preexisting technology and was curious if anyone else had run into similar issues.
