I have an extremely minor quibble: most of the world’s countries using an AC voltage over 200 volts are using 230 V single-phase nominal. Whereas 240 V single-phase really only appears now in former British colonies, and many have since redefined their nominal voltage to match the 230 used everywhere else. This includes the progenitor of this voltage, the UK, as part of harmonization with the European power grid – when they were part of the EU – but that was accomplished by raising the EU upper voltage tolerance to include British 240 V single-phase.
North America does have 240 V split-phase, which mostly works fine for unpolarized 208/230/240 volt appliances, but it’s just not common to provision for general-purpose circuits – even though we could do it . Would that redeem America as a civilized country? The jury is still out…
I sincerely appreciate this. You have further proven that I don’t know anything at all about other countries.
And an additional thanks for the thorough explanation in the linked comment. As a layperson, I knew different options existed, but I didn’t know what they were, or why.

Not anymore. I just showed the jury the top ten news headlines. They’re come back with a verdict. 😏
