That would work well with the infamous 3 kW British tea kettles.100 A requires, perhaps, AWG 0 = 8.25 mm diam = 53.5 mm2 wire.
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

Quote from: TimFox on October 08, 2023, 09:20:07 pmBy 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.Interesting! Thanks for the insight. Btw. reading about US plugs I learned about "outlet challenge" which involves partially inserting the brick portion of a mobile device charger into a wall outlet and then sliding a penny down onto the brick's exposed metal prongs. The result is a blast of electrical sparks.

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!
I've never seen most of them in person, I guess most are outdated.I do however have a UPS with one of these plugs:I've had a couple of conversations with the electrician on whether I can get this hooked up in the house. The plugs are rated for 32A but I'll only be pulling 25A tops.
I assume in America that fan runs at half the speed?
Quote from: tom66 on October 05, 2023, 02:49:22 pmA decent plug is Schuko, but it has other issues like lack of polarisation in most cases.The reader is reminded of the fact that we usually are conveying alternating current over these plugs, which means that polarisation is wrong 50 or 60 times per second. Hence, "polarisation" is for people who still think in DC. The only wise move is to regard the two pins as equally dangerous and untouchable. All other moves are loser moves. (Three-phase is another game, of course. But since the english-speaking world is afraid of it, because Edison, most people never get to have it. )

some dumbass swaps phase with neutral
Quotesome dumbass swaps phase with neutralNot that uncommon event for a few years post 2004 ,even the dno got confused
How? We have PEN for the majority of homes in the UK.
I'd like to see a new world standard, but likely it won't happen in my lifetime. USB ports are fairly universal, and some variants can deliver up to 240 watts.Of course a little USB C plug would be ridiculous tor a kettle, but I'd like to see a "big brother" version for higher wattage.But that's just me.

This persons needs to be kept very far from any standardisation process.
USB-connector chargers for low-power objects are small, and when the standard changes yet again they can be replaced with newer ones.The NEMA-standard US sockets will remain in place in the US during those transitions.In other countries, they shall stick with their standards, as well.
