@rfreling @leoncowle @caseyliss it's mostly because of the low wattage available from standard plugs, and then the absolute madness they come up with to compensate (240V goes into the house, after all!). Europe has other plugs but you'll never encounter them in common usage because 240V@15A is pretty good for everything you might use inside 4 walls. The 20A & 32A plugs look a lot more like an EV charger plug.
