What is the difference between UL and ETL?

A Both UL and ETL are recognized as the Nationally Recognized Testing Laboratory(NRTL) by OSHA, they function to provide independent evaluation, testing, and certification according to the same North American product safety standards.

     Van-Sheen Electric has chosen to use two National Recognized Testing Laboratory (NRTL) marks that support the same North American product safety standards. The marks of UL or ETL on the products represent the company who performed the safety standards testing.Both testing laboratories perform periodic inspections at manufacturing facilities to ensure compliance and quality. So the only difference between them is the services to their customers.
