Then nominal EU phase to phase voltage is 400VAC with a +6/-10% Tolerance.
Distribution is Three Phase Star, Earthed Neutral.
Some countries are still a little behind in the voltage harmonization
e.g.. Belgium is a nominal 380VAC. Other have not
changed as they fall within the tolerance limits already, e.g. the UK is a
nominal 415VAC
Generally with switch mode supplies, provided your incoming wiring feed is
changed to take into account the Star and not
Delta, configuration. They can accommodate the voltage difference.
