Jay, the 230V is the European situation: they have 400V 3-phase power and 230V per phase. The situation from history was that most mainland Europe was 220V while UK used 240V so they agreed on a compromise, 230V everywhere and they could still use the old generating equipment but had to require it to deliver either 220V -6%/+10% (207-242) or for the former 240V countries, 240V -10%/+6% which is 216-254 so that if you produced equipment for 230V +/-10% then it would work everywhere: that range works out to 207-253V
