Jup, that’s a really good feature. You can get aftermarket child shutters for EU style plugs as well, but they require you to twist the plug before inserting, making them kinda inconvenient, and they have to be specifically installed by parents. Though I don’t think that’s the worst thing in the world. After all, we don’t make any of our other products or home designs toddler safe by default. It’s generally regarded as the parents responsibility to ensure their home is child proof before they get a child.
But the UK version of just having it in every outlet as a hidden feature that you wouldn’t even notice if you don’t know it’s there is definitely the best approach.
(Though it does make low form factor UK plugs almost impossible, because every plug must have a ground prong, even if there’s no actual safety need to have one)





No it isn’t. It’s debatable if the safety features are still necessary with modern wiring and electric code imporovments, but the features are objectively there, and they objectively make the plugs safer.
And the design of these features wasn’t because of “substandard” wiring. It is because the UK used to use ring circuits in old houses, which are unsuitable to be protected by central breaker boards with breakers for each room, necessitating fuses in the plugs. That doesn’t make the system any less safe. As long as a fuse is present, and the circuits are adequately sized, where precisely on the circuit a fuse is located is irrelevant.
Also, the fuse inside the plug provides an utterly unique advantage that no other country has: The fuse can be used to protect the external wire from over current. Centralised fuses are exclusively designed to prevent over current on the main, internal circuit, they don’t give a crap what happens on the other side of an outlet. A central fuse protecting a 16A circuit will do nothing to stop you from pulling 15Amps through a 3 amp cable. A fuse inside the plug, appropriately sized for those 3 Amps, will in fact protect the cable itself. This is particularly useful for extension cords. Other countries without fused plugs need to either just flat out mandata ALL extension and multiplug cords be capable of safely handling the maximum current of a household circuit (e.g. Germany) OR just ignore that rather major safety hazard entirely and just kinda hope that nothing bad happens (e.g. USA) (if you’ve ever wondered, that’s specifically why chaining extension cords together in the US is considered dangerous)
