But that is crazy! Pardon my French, but *there are no emission limits for a 30 A equipment in the standard*. What you are saying is that a purchaser might impose contractually limits appropriate for, say, a 5 A equipment to a 30 A equipment, which is indeed true but hardly more realistic than a requirement for no emissions at all. It falls into the same category as the all too common 'contractual requirement', 'The equipment shall comply with all British, European and International Standards.'.

I suggest you get the edition of the standard that is notified in the OJEC and see for yourself. Be careful! CENELEC in its 'wisdom' has got out of step with IEC, so there is an amended First Edition of the EN AND a 'Second Edition' which is actually 6 months out-of-date compared with the amended First Edition, unless you are into kitchen appliances. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero.
