I think there is some doubt as to whether such a product is ITE or not, but I think the standards you cite are acceptable. As regards the mains supply, the transient voltage could be up to 6 kV in some parts of the world, and with overhead power distribution. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
