But when was the last time you saw a plug rated (just a random example) 250V 3(phase)Y 75A when it means 25A per phase? the 75A rating is definately 'per phase'.

I've just looked at all the draft copies of this standard(that I have), and the older version TR IEC 1000-3-5. Still only says 75amps. Again no "per phase". I would have to say if TC77A wanted it to say "<75A per phase", it would be in there.

That would allow 3 phase products rated greater than 25A per >phase to fall outside the scope of EN61000-3-11! That certainly needs to be clarified. I'll set the wheels in motion immediately. It SHOULD say 'per phase'. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
