Hello everyone. Just found the forum today and hope to be on here regularly. Not sure if this is the best forum to ask this but does anyone know the legalities of selling new old stock? I have access to many older Whole House Surge Suppressors that were produced back in the 90s. They were all approved by U.L. 1449 at the time but I have read that U.L. has newer testing for these type of products today? Thanks for any input.
