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

Best and safest current for all purposes. --- End quote --- 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. --- End quote --- You can keep your clunky plugs for kettles and such. Most everything else can run on safe current. |

--- Quote from: PapierzToaletowy on October 08, 2023, 10:20:26 pm --- --- 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. --- End quote --- 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: --- End quote --- Yes, social media are popular among the clever young people. |

--- Quote from: DavidAlfa on October 08, 2023, 08:53:06 pm ---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! --- End quote --- I've never seen most of them in person, I guess most are outdated.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. |
