Acceptance Testing

The purpose of acceptance testing is to insure that the components within the system and the system as a whole, are installed in conformance with the National Electric Code, InterNational Electrical Testing Association (NETA), and American National Standards Institute (ANSI) standards required not only for commissioning new equipment but for testing the reliability and performance of existing equipment. Acceptance testing allows the user, customer, and other authorized entities to confirm that the system or component is ‘fit for purpose’. It is through such tests that the contractor and end-user is assured that electrical equipment is safe and reliable
