Man harmoniserade nätspänningen i Europa där UK tidigare hade 240 V och resten av europa hade 220 V
genom att lägga sig på 230 V istället.
This was achieved by changing the tolerances of previously existing supply standards. UK voltage to 240VAC + 6% and - 10% and European to 220VAC +10% and -6% (thereby creating a manageable overlap) and we would call these two combined 230VAC, despite the fact that nobody was intentionally generating at 230VAC!
