What type of endorsement does the Vairday have? Has it been tested by a 3rd party professionally trained electrical engineer?
Yes, the surge suppression capability of Vairday has passed the rigorous testing at the highest possible level of UL1449 3rd ed. The savings have been tested by dozens of third party engineers and electricians including Northrup Grumman. You can see the results of that test on our “Success Stories” page.
