  • Virtually all systems protect again shortcircuit at the breaker lever. Japan mostly has no ground but a RCD/GFCI for the whole house.

    Basically how this works is that it checks if all the current leaving on the live wire is also returning on the neutral wire. If the current returning on the neutral is less than the one leaving then a part of the current must have found another way to get to ground (through your body for example) and it breaks the circuit hopefully before any danger could happen.

    Now this doesn’t make ground useless, there are 2 different protection systems that work in different ways, and sometimes protect in different scenarios too, the RCD is also an active protection that can and fail, compared to ground wich is passive.

    Having both is ALWAYS safer


  • Here in Romania we use Type F but sometimes also install a modular Type L socket alongside regular ones because it’s smaller and you can fit 2 of those in place of a full Type F/Schuko one. We don’t use Italian plugs and so only use them for europlugs (max 2.5A and double-insulated so no ground needed) (Kind of something like this)

    I do find it kind of sad seeing them getting slowly replaced even in Italy (I know it won’t fully happen of course) because they’re very space efficient
