--- Quote ---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

our standard connector  for larger power is the ceeform(IEC 60309) a 125A 3 pin would be about 4" in diameter and 12" long

--- Quote from: Connecteur on October 08, 2023, 07:31:48 pm ---I say that worldwide everyone should switch to 30 volts DC.  Best and safest current for all purposes.

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.

You can keep your clunky plugs for kettles and such.  Most everything else can run on safe current.

--- Quote from: TimFox on October 08, 2023, 09:20:07 pm ---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.

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.  :palm: :palm: :palm:

Yes, social media are popular among the clever young people.

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I've never seen most of them in person, I guess most are outdated.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.
