Help in assembling the shield in the apartment
Good afternoon! I collect the shield in the apartment on my own and questions arose. Please tell me what to do. On the landing there is a single-pole machine for 50 A, then in the apartment there is a meter, after a two-pole machine 63 A, then wiring into two difavtomats (washing machine and dishwasher). And also on the machines 32, 20, 3 × 16, 2 × 10. Am I right or wrong?

If there is a 50 A machine on the landing, then it makes no sense to put a higher value after the counter. In the event of an overload, the machine on the landing will be switched off, since it is of a lower nominal value. That is, both there and there, put on the same face value. The rating of other machines you choose based on your wiring diagram - the main thing is that they protect all wiring elements from overload. You put differential machines or RCDs on the most dangerous electrical appliances from the point of view of electric shock, if, in addition to the washing machine and dishwasher, there are no such electrical appliances, then that’s right. It is also recommended that in addition to the automatic machine, an RCD or a difumtomat, which performs a fire function and reserves the difavtomats of the outgoing wiring lines, be put on the input.
And can then use the machine on 63a, as a simple knife switch?
