Re:Why does the USA use 110V and UK use 230-240V? by dusted on Tuesday August 29, 2023 @04:05PM (#37313172)
In Denmark, most homes have 3 phases of 240 volts, along with neutral. (and protective ground, of course)

More power in less copper. Most items do fine with 240 volts, but high-power items like ovens and electric cars can use two or three. Also, we have the CEE 5P plugs, which look awesome and allow you to draw a lot of juice from a single point.
