What voltage relay to choose to enter the apartment?

Hello! Need advice on the correct layout of the electrical panel for the apartment. So, there will be new GOST wires everywhere, input on the site is a 2-pole automatic machine, 32 A. Input in the apartment panel 25A, (hereinafter the question). Next went the group on the differential. 16A automatic machines to sockets and to the light of 1 p. 10A automatic machines, and so you need to put a voltage relay after the input 25A. Question: how to calculate how many amperes to put it on and whether to protect it before or after installation?

    The voltage relay is placed one step larger than the machine in front of it. In your case, 32 A.

      And the relay needs to be set in front of the home introductory at 25A and another question, and no additional protection is required for it? And if instead of this, 25A will it be better to put a difavtomat with the same face value of 100Ma or not?

        The relay is placed after the introductory machine, the machine standing in front of it is a protection. If there is a third grounding conductor, then the difavtomat can be delivered, but still after the introduction.
