As part of Alliance’s commitment to quality, all of our product designs undergo a variety of tests to assure they will perform reliably season-after-season in a variety of climatic and weather conditions.
In addition, we test our products for electrical performance and safety. We partner with ETL Testing Laboratories to perform independent testing to verify performance of our transformers and other components. ETL tests for conformity using the UL 1838 and 2108 standards. In addition, our factory is an ETL-certified facility.
