There are types A (Japan), B (US), C (EU), D (India), E (France), F (Germany), G (UK), H (Israel), I (AU) and so on: in which all have a distinct plug shape and differences in prongs. Type A plug is just two straight prongs without a ground while Type B is nearly identical to A but with a ground connection and Type F has no ground attached to the outlet while Type E does, usually this is solved with a adapter (for electronics that are dual voltage and support 50/60Hz frequency).
However, household appliances are typically region locked in the sense of being singular voltage (like electric kettles, toasters, refrigerators, washing machines) since those are intended to not be made for travel (mainly for domestic use supporting only a single plug type) unless you have both an adapter and a transformer. You can’t just plug a 120v 60Hz Toaster (B Plug) onto a 230v 50Hz outlet (Type F socket) with an adapter alone as that’ll blow the fuse.
Most modern electronics (as in laptops, game consoles and smartphones) support dual voltage and frequencies but their default plug type is region locked, so if you’ve bought a PS5 in the UK importing it into the US (the default cable is Type G that comes with the packaging when plugging into a TV) unless you swap cable for a Type B plug but it’ll work fine. Why is there no unilateral plug type that’s “region free” when discussing plug types found in appliances.
in EU there are really only two standards. for single phase loads up to 3.8kW, regular 16A plug is sufficient. above that, 3-phase 5-pin 32A plug (most common of them) is used which can deliver up to 23kW. there are common variants of 3-phase 5-pin plugs rated up to 125A that can deliver up to 89kW
and uncommon up to 800A variants that are also part of the standard, but it delivers up to 0.57MW and it’s a bit sillyi’ve found 1999 version of iec 60309 standard and biggest connector defined there was 250A. actually i wasn’t able to find vendor for currents higher than 125A, but for 125A, standard expects 16 to 50mm^2 cable and for 250A 70 to 150mm^2. lower ends of these ranges would be insufficient for full load and would require limiting current appropriately. maybe higher currents were latter additon. either way 32A is almost-standard and anything above that is in some way custom job
The wiring in the wall can handle 125A or even 800A?! What the fuck wire gauge are you guys using over there?
50mm^2 for 125A, just under 8mm diameter solid copper rod if it was solid copper rod. but it’s stranded so it’s a bit bulkier than that, bundled five per cable. it adds up to some 4cm in diameter
150mm^2 obviously (tho only for 400A). Don’t know that I’ve ever seen 800 amp powerlock, I guess they would be 240mm^2 and above.
I think they are talking about more industrial/commercial applications that use ceeforms or powerlock for 1 or 3 phase: 16A, 32A, 63A, 125A (I know, we were so close). Anything over that is powerlock, and I don’t know if any single phase powerlock.
