There's a bit of a difference though.

In Europe the 127V split phase systems were very much in the minority. 220V 50Hz phase-to-neutral systems were far more common place and became the absolute norm after WWII.

For example, in Ireland 220V phase-to-neutral was standardised upon before 1923. From what I gather, it was also the norm in quite a lot of other countries too.

Because the 127V systems were only in certain areas, appliance makers didn't bother catering for it.

Before long, nobody made 127V appliances or light bulbs, so systems were all wired to provide 220V.

Does anyone know what type of plugs and sockets were used with the old 127V systems? Were they any different from Schuko ?

Obviously there must have been quite a few different types around as there was no European standards at that stage.
