This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

While the US system gets called 110/220, my house actually puts out ~242v. Right now I have a smart plug saying 121.5v.
And since you mentioned the word "plugs", here are our 220 15a and 20a outlets.
120/240 is the nominal voltage in North America. 110/220 is archaic/colloquial/wrong.
And the standard includes a plus or minus that I don’t remember: it’s unreasonable to expect an exact voltage and everything is built with that in mind
