Is it possible to connect an RCD or a difavtomat without grounding?
Hello. I want to connect the boiler to electricity. Dif or RCD with a gun does not make a difference. The apartment includes phase and zero, there is no land. Can I connect a diphole or an RCD without land in another way, but so that protection remains?

Hello! Yes, connect the RCD to two wires, do not connect the ground anywhere - because she is not there.
Then why put an RCD, without land it will not perform its functions. A normal machine is enough. In the event of a short circuit or load, the machine will operate. And RCD, as far as I understand, will work when an electrician leaks (it will break a water drop from wear) and here the RCD will work. But without land there is no. As I was offered to describe now. RCD, from the left, the phase enters from the top, exits from the bottom left. Zero enters from the top right, zero goes from the bottom right. But connect the ground (from the boiler) to the upper right of the RCD by zero. Is this an option without land?
Without earth it will not work, but without an RCD when you touch the body of your heater - you "work", it is possible that for the last time. So do you have land or not? What land are you going to connect? If you are going to zero a contact for connecting the earth without earth - note that if a zero is burned out, a phase will appear on the case! A leak will work without your circuit if you touch the case, but choose an RCD with a smaller trip current.
