Why RCD is unallowed in TNC system? I think it is useful for preventing indirect electric shock

Why RCD is unallowed in TNC system? I think it is useful for preventing indirect electric shock. For example when a fault happens (phase to metal body) and a person contacts the metal body, current flows from his body and goes to the earth. So Unbalancing current of phase and PEN inside of RCD make it to be triped.

    So many thanks. Do you mean in TNC system, There is unwanted tripping of RCD so because of this we can not use RCD?


    How many conductors are there on the consumer's side of the supply and of these two (whoops, gave the clue away) what are their functions?


    Next, how does an RCD work?


    Regards
