Is the Smart GFCI Outlet UL listed?

Yes!  All Leviton products have been reviewed and approved to meet the NEC standard.  While the UL mark has a long history testing electrical products, there are several companies that perform independent product testing.   The key is the testing labs must be a Nationally Recognized Testing Laboratories (NRTL) that test to the same harmonized Canadian Electrical Code (CEC) and National Electrical Code (NEC) standards as well as UL standards. Leviton prides itself on obtaining third party safety certification for all its electrical products and utilizes several of the NRTL’s that are authorized to test its products (including UL).  If you have further questions, please contact our technical services, we would be happy to provide assistance.
