Sweden had a weird 127V DC plug that looked a bit like an ungrounded Brazil (?) plug.

As far as I've ever seen, Brazil uses either European round-pin plugs or American parallel flat pin plugs for A/C.

Voltage is anywhere from 110 to 240 -- at 60 hertz, depending on what part of the country or what city you are in.

Don't go by the receptacle configuration.

From what I've read, the USA used standard two-pin plugs for low-voltage DC systems on farms as well as AC.

Ranger, do you have a picture by any chance of what you're talking about?
