On: History of the Italian electrical system

[john01dav]

This is a very interesting topic to me for some reason. I'd enjoy a website full of such explanations for a huge list of countries (I see that this website has some similar things.).

Also, I have found myself passively curious before about how far back you could go and find an outlet that you could plug a modern device into and have it work as expected.

Seems like a regular US lightbulb would have worked in 1881: https://en.wikipedia.org/wiki/Edison_screw

And ungrounded US sockets could have worked in the 1910's: https://www.plugsocketmuseum.nl/NorthAm3.html

Definitely give the rest of PlugMuseum a look. There's tons of info there.
