Re: [PSES] 3 phase 408V in EU and Emissions Classification

Carl, Standard AC mains voltage in the EU is 400V +10%, -5%, 3P. This accommodates everything from 380 V nominal legacy systems through 440 V nominal legacy systems. The same is done for 1P systems: 230V +10%, -5%, so the 408 V nominal that your customer is asking for is accommodated within

Doug, Excellent response. So if I'm understanding you correctly, the 408 V ac supplied to an apartment complex can be via the low-voltage public AC mains. Thanks very much, Carl On Thu, 19 Nov 2015 11:13:00 -0500, Douglas Nix wrote: Carl, Standard AC mains voltage in

Carl, An apartment complex is a shared low-voltage distribution network, and would be viewed as Class B. The concern is that conducted emissions from one user will affect equipment in another user’s premises, since there is no attenuation by the substation equipment and the intervening MV
