Question for electricians? and got a better answer
Response from Антон Владимирович[+++++]
True, now RCDs are put instead of the input circuit breaker, but this is not right and not literate! The light in the house should not turn off when there is a malfunction in the socket. Should be an input fuse, and after him RCD on all the circuits leading to consumers. I.e. one automatic circuit breaker for light, another for sockets, a third for the electric stove, etc. In most apartments, the first option is practiced in order to save money. Since RCD thing expensive. But it is ALWAYS necessary to check! Use at least an indicator screwdriver, you will live longer. No one knows what drunken electrician did the connection in your apartment?
It is true now RCDs are put instead of the input circuit breaker but this is not right and not competent! The light in the house should not be turned off when there is a malfunction in the socket.

Ie to the light - one RCD sockets - the second electric stove - the third, etc. In most apartments, the first option is practiced in order to save money. Since RCDs are expensive.

If it's wired right, yes!
yes always! otherwise what is the RCD for?
should. but there are exceptions. preferably check after disconnection with an indicator screwdriver.
If the screwdriver shows there is a phase you need to change the connection.
The RCD cuts off the voltage in the circuit on which it is installed. If there is any other parallel circuit going into the apartment, it will stay on. But this should not be the case, i.e. RCDs are put on the whole apartment.
igor! Look carefully at Sergei's diagram.
Ideally, you can put differential automatic diffs. That is a diff for each circuit. Differential is a circuit breaker + RCD, combined into one two-module device. And don't skimp, this is not the case. I recommend ABB, Siemens, Legrand.
Yes, it is true, but you need to check the voltage on the wires with an indicator or if not, you can use an ordinary incandescent bulb connected to the socket
