What to put in the beginning: RCD or voltage relay?

Vitaliy asks:
Please tell me if there is a sequence of installation, RCDs and voltage relays, or voltage relays and RCDs. RCD Chint, 40 Ampere, leakage current 30mA. Voltage relay Bison D40t, thank you for your reply.
The answer to the question:
What kind of RCD are we talking about? Do you want to put on an RCD input? I believe that a voltage relay is better to RCDs, but in general it is not too critical. Just if you connect the RELAY after an RCD, the RCD can start to falsely - you will notice it right away.

    After a relatively energy-supplying company or consumers?

      everything is said regarding input, i.e. the input from the mains comes in (let there be a private sector high-voltage power line), it goes to your meter, and you put your shield on. It turns out, as you say, then “after, regarding the energy supplying company”.
