I hate to disagree with my customers BUT: In Canada and the USA, the CSA certification and UL listing do NOT constitute "APPROVAL".
The Authorities Having Jurisdiction (AHJs), for our purposes the electrical inspection authorities in the States or Provinces do the approving. They normally do that by observing whether or not the equipment carries the mark of an accredited certification or listing agency. If they see that mark, they approve and stop their investigation there. (THEY DON'T HAVE TO !!!!!) If they don't see that mark, they may choose to investigate the product themselves, or, they may instruct the manufacturer to go and get it tested in a place of their liking. They will than approve or disapprove on the basis of that investigation. The certification organizations are NOT in the business of "approving" equipment, they are in the business of certifying that the equipment meets specific requirements. An electrical inspector is responsible for determining whether an installation should be approved. I believe you could sue the pants of him if he did NOT approve, because the equipment does not carry his preferred mark. However, if the equipment does NOT carry that mark, he is not going to approve before he has received assurances in one way or another that the equipment meets the applicable requirements. He usually is ill-equipped to do that verification himself. Regards, Vic
