About
For an industry burdened by too many parts-per-install, UL 3741 represents hope that we can avoid using too many components to satisfy safety regulations, via exhaustive testing.
Problem is, everything in a UL-3741-listed array needs to be specifically listed with everything else. How are we supposed to know or remember what all options are out there with this spiderweb of certifications?
This site is an attempt to catalogue all existing equipment and implementations, so you can pick what you know how to work with and find sister-rated products for a properly listed array. You can click one of the links below, or search the site in the sidebar for a product you want to use.
If you can’t find a product that you think should be listed here, let me know on the contact page, where you can also subscribe to updates!
