I very carefully **didn't** suggest you should go to such extremes! Yes, if you have such a product, it probably *is* OK to rely on your UL evaluation, but backed up by your **own** check on possible effects of the differences between the EN and the UL. There is NO requirement to use a test-house for things you can do yourself (or for anything, for that matter). -- Regards, John Woodgate, OOO - Own Opinions Only.
