DavidAlfa:
I prefer the Australia sad outlets. The higher the power the sadder they get.
They probably were designed in times where electric energy was really expensive!


TimFox:
Yes, we have "high power" in industrial and commercial locations as well.
Please parse my statement literally:  I was comparing 240 V to 120 V, and 240 > 120 in all nations.

Is 34 kV enough for you?
TimFox:
By the way, a typical US home-kitchen electric stove, with four burners and an oven, runs on 240 V (line-line) single phase, pulling 22.5 kW and requiring a 50 A circuit.
If it plugs in, the US outlet is a four-contact NEMA 14-50R.

100 A requires, perhaps, AWG 0 = 8.25 mm diam = 53.5 mm2 wire.
--- End quote ---
the plug would be bigger than the kettle
TimFox:
In the US, I think the "regular" NEMA series only goes up to 60 A, for AWG 4 wires.  It is roughly 2.5 inch diameter.
A "pin and sleeve" NEMA 4X for 100 A is roughly 3 inch diameter.

It would make the tea kettle difficult to use.
