You can get RCD sockets if you want in the UK (and mainland Europe too). But we generally at the minimum have sockets protected by an RCD (which is the same thing) and in more modern installations all circuits are protected by one.
In my country the differential switch is mandatory, every circuit must be protected, be it from a main one or separate ones for each circuit. I'd be surprised if it weren't the same all over the EU.
For new installations in the UK that's true. But my house, for example was wired in the 1990s and has an RCD only on the sockets (the reasoning I think was that an old style incandescent bulb failing might trip the single RCD taking out the whole house power, but could be wrong).
Since the early 2000's they changed it for new installs to be RCD for all circuits I believe.
Sure, but as far as I could find, even those have trip rating of 30mA. But perhaps I could find some with lower rating.
I think 30ma is about normal. There's a good reason, in an average socket ring (or even radial) you will always get SOME leakage. So there's always going to be a common sense allowance made depending on whether it's a single socket, a small radial or one or more rings.
Yes, and 30mA, even at mains voltage, will not kill someone. Static shocks can vary from 1,000V to 500,000V and are usually around 5mA for reference.
