Mildly Infuriating

American here. I may be in the minority, but I think this plug design is absolutely stupid. I get that it has safety features, that you can put a fuse in the plug, that the outlets have switches, etc etc etc. But it is absolutely fucking huge. Ridiculously huge. And anywhere that you have multiple devices you want to plug in, it is totally impractical because it is so fucking huge.

The fact is, very very few devices need 240v 13A. Yes I get that it is useful to have this ridiculous amount of power so you can boil your tea kettle in 35 seconds, but other than that very few household appliances need anywhere near that amount of power.

So the result is a cell phone charger, which at the very outside is pulling 20 or 30 watts, is plugged into this giant ridiculous monstrosity capable of supplying 3000+ watts. And in reality the only appliances that use anywhere near that much are cooking appliances and space heaters.

Meanwhile the US NEMA 5-15 is good for 1800 watts, plenty to run almost every household appliance, with the longer ground pin and an appropriate outlet it supports tamper resistance shutters, the thin flat pins resist the insertion of foreign objects into the outlet, and you can fit many outlets in a small space.
And it doesn't destroy your foot when you step on it, as a nice bonus.

It needs an unearthed version without the shutter-opening pin, for things like low-power electronic devices with figure-8 mains sockets, phone chargers and such.

Of course, some BS1363-stan will inevitably show up to argue that as this is a crucial safety feature, unearthed connections should be illegal, much like the Australians who argue that bike helmets should be mandatory in Amsterdam.
