Check the circuit diagram of a country house

Vasily asks:
Country wooden house in two floors. I am going to implement the following scheme:

1. C6 - 1.5 mm (Imax = 16A) - 16A socket - refrigerator (power up to 1 kW, current up to 4.5A)
2. C6 - 1.5 mm (Imax = 16A) - light on both floors and porch (a total of 1.0 kW, current 4.5A)
3. B32 - 6.0 mm (Imax = 40A) - heating (convectors connected without sockets) ground floor and terrace (total 6 kW, current 27.3A)
4. V25 - 2.5 mm (Imax = 25A) - stove, kettle, water heater, socket 16A (total 5.0 kW, current 22.7A)
5. C16 - 2.5 mm (Imax = 25A) - sockets 16 A first, second floors, terrace (total 3.0 kW, current 13.6 A)
6. C25 - 2.5 mm (Imax = 25A) - a street shower (2 kW) and a street socket for a mower, inverter and other tools (total 4.5 kW, current 20.5A)
The questions are as follows:
1. Are there any significant errors in the circuit?
2. Is it possible to lay two or more cables in one corrugation?
3. I want to use the NYM brand, is this the right decision?

The answer to the question:
Everything is good, but it would be better to add an RCD to the SHOWER, also a 25A machine is not needed there. Firstly, they put it on sockets at 16A and in this case you need to divide it into separate lines, and secondly, are you sure that you need to turn on both of these consumers at the same time? You can put 16 and turn on the shower and mower separately.

It is allowed to lay cables in blind ducts with 35% filling of their total area (PUE p. 2.1.61), this rule can be extended to corrugation. That is, just pick up a larger corrugation. But are you sure you want to save so much? Your line is not along a kilometer ...

    Good afternoon.
    Country house. According to TU 8.5kW 220V. It is required to establish PZR and OP.
    What set of equipment (preferably Schneider) is needed and in what sequence (from input) should it be installed?
    Now: A25 Schneider submachine gun, counter, RCD Schneider.

    To answer
