【About Safety Certification】Are the US Safety Certification (CSA-US, ETL, UL...) for connectors same as Canadian Safety Certification (CSA, c-ETL, c-UL…)?

It is a Recognized component for connector in  US Safety Certification & Canadian Safety Certification, but the Standards are different.

In the US Safety Certification (CSA-US, ETL, UL...) the Standard is UL 1977.

In the Canadian Safety Certification (CSA, c-ETL, c-UL…) the Standard is CSA-C22.2 No. 182.3.

Although the US Safety Certification for connectors are not the same as the Canadian Safety Certification, it is recommended that manufacturers apply for U.S. and Canadian safety certifications at the same time; that is, the product is considered to meet the safety certification requirements of the U.S. and Canada at the same time!

In order to avoid the retesting and delays in Certification body. It is necessary and important to fully perform structural check and product pretest before applying for connector safety certification!
