Difference Between UL Listing And ETL Listing?

- Apr 03, 2018-

UL and ETL are both what are called Nationally Recognized Testing Laboratories (NRTL). NRTLs are in place to provide independent safety and quality certifications on products. Electrical appliances typically require their certification (especially 240V appliances). Some charging station manufacturers do sell unlisted products; it is very important to check for the UL or ETL mark before purchasing. 


UL develops the testing standards and tests for them. ETL tests to UL standards. In order for an inspector to sign off on a permitted installation for an EVSE, the National Electric Code requires the EVSE be NRTL listed.


Biadi-cable chooses UL for its Lan cable testing; the selection of which laboratory depends on which company provides the best value for their service that we can then pass on to our customers. Consumers should check carefully before buying to be certain that is either ETL or UL listed.
