Diagram of electrical installation in the apartment - opinion

Hello

The time has come to buy your own M. The family and many friends working in various industries (tiles, plumbing) offered help in the renovation, but the problem arose with the electrician. Namely, I do not know anyone who could help and advise me from the heart, so my friend recommended his friend to me, etc ... doubts :)

Below in the attached picture is the wiring diagram. The important (it seems to me) parameters are:
- total power connection of the power to the apartment 15kW
- electric wires, lighting 3x1.5mm2
- remaining wires 3x2.5mm2 + 5x2.5mm2 to the heating plate



As I do not know my colleague (I do not know how good an electrician he is - because having paper is not everything), I am asking for an opinion on what is on the "diagram" and possible changes and suggestions. If you have any questions, I will try to answer my best

greetings

For washing machines and refrigerators, we provide protection with the B characteristics, not C. If they crash, it means that there is something wrong with the device, because it is not a threshing machine with a heavy start.
I would break the sockets and lighting into three phases, and I would make two circuits for lighting, so that the darkness would not come at once

Why are you protecting the RCD with a redundant module? I will not mention the denominations and characteristics and some imprecise description of some circuits. Where's the circuit for the dishwasher? You can still count, but because of the time it is enough.
Maybe read on the forum first. There were many similar topics.

Apart from the fact that the circuits work in the L - PE system.

Somehow, no one wants to point out that two cables are not everything. Performing a proper installation is based on knowledge, not on connecting two cables. We know nothing about the bathroom, for example, about equipotential bonding. It is impossible to properly prompt from a distance. I close the topic so as not to provoke answers that may be very wrong.

Please look for comments on other similar topics.
