Well that's news to me! I'm jealous. I'll bet you can preheat an electric oven in less than 20 minutes. I see the successor to the 16A Perilex connectors you are referencing is IEC 60309 which has an "extra low voltage" version with a smaller, 42mm diameter (1 2/3") plug good for 16A or 32A. 16A devices will fit in a 32A socket, but not the other way around. So that seems to be a 1.3kW and 2.6kW solution. Sign me up!

UK here: We don't have three phase (well its not common) but we can heat an oven up to 220c(420f) in 7 minutes. I think its a 3kw oven. its on a 32 amp (isolated) breaker.

  Had something to toast so I tested mine too (3x 16A @230V). Took 4:52 to heat up to 220°C

  I've never ever seen it in the UK, but I did live in a house with a flat on a separate meter, that as it turned out was on a separate phase. I only discovered this because there was a fault on the line for only one phase, and only after checking and changing every fuse (wire), and unplugging every electrical item. Grr.

"So that seems to be a 1.3kW and 2.6kW solution" Germany is 230v so that would be more like 3kw and 6kw. I'm in the UK (also 230v) and a standard outlet can do 3kw, I think fuseboard fuses are 32amp so I don't know if 6kw is a practical upper bound though (edit: On 2nd thoughts I'm not even sure this is relevant to 3 phase).

  Pedantic: Standard outlets are 16A in mainland Europe, so 3.7kW. Modern single ovens can also be connected to a standard single phase outlet rather than a dedicated circuit. In my kitchen the induction cooktop is on a 16A three phase circuit, and all the other outlets (fridge/freezer, oven, dishwasher and appliances) are on a 16A single phase circuit. 5:11 from 20°C to 220°C

    Wouldn't pedantic be 3.68kw? I've never actually come across anything higher than 3kw, also a 16amp fuse isnt that precise, you could probably get up to 20 amps without it failing. The hotter you run it the quicker it fails though, so if you're regularly running 3.7kw through a 16 amp fuse, you may well find it failing, not through an underlying fault of anything plugged in to it.

  >I think fuseboard fuses are 32amp Most cables are 16A, so the outlets are 16A as well. Also UK uses 240V, not 230V. 32A circuit breakers would make the cables burn when overloaded.

    Flex cables might be 16amp, individual sockets are 16 amp though, so if you have more than one of those on a ring main...

      normal fuses (in the fusebox) still have to be 16A (B or C class), the main fuse can be anything 32-50A or even tri-phase 50A. >ring circuits up to 100m, cookers and electric showers up to 7200W Normally those tend to be 3phases. Of course it's possible to get over 16A on a single phase and a circuit breaker but that's quite a non-standard option. The issue is that if the fuse/circuit breaker is rated for 32A in a standard application (i.e. an outlet) the cables are likely to burn 1st.

        I think we might be getting our wires crossed :) I'm talking about the UK here, which I understood to be similar to the rest of Europe(?). That's a UK website and 3 phase isn't common here. I've just double checked my fuse box, and I have a 32 amp fuse for my socket ring main. Don't forget for a ring main the current is spread over 2 wires, so if theres 32amps power draw, theres only 16amp on each side of the ring.

I'm in Romania and it heats to 180C in about 3 and a half minutes.
