    Hello,

    Recently, I changed the old single-phase connection to a three-phase so-called strength. But after connecting several protections, the residual current device trips automatically. I don't know what could be the cause and I am full of hope that someone here will help me. In a moment I will put below the diagram that I made and which I used at home when connecting.
    I would like to mention that the house has an old installation made of copper, but without PE protection, and therefore in three sockets zero-bridging with a protective pin was used. During the test, the devices from these sockets were disconnected to be sure that the differential would not be turned off automatically. Unfortunately, the security was released.
    Diagram:
    Electrical installation - trips the residual current circuit breaker
    Is the connection according to this diagram correct?
    Do i need to correct anything?
    Currently I had to disconnect the zero connected from the differential to the strip and I led from the surge arrester (where the main zero is connected) to the strip - because if there was no light I need to have at home, but you know the residual current switch does not protect, at least at home where you would have to lead one the core of the PE cable to the sockets.
    The problem arises with the garage where there are several power sockets where the protective conductor is led.
    How to find out what is the cause?
    He can disconnect the zero going to the garage and check if the residual current device will trip.
    Then plug this zero back in and disconnect the zero going home and check if it breaks? because maybe the fault is on one side but that's my guess.
    The grounding has been made new. Drilled probes connected with a galvanized flat bar "hoop"
    I am asking for help on the subject.
    First of all, if I made the diagram correctly.

    Greetings.

    No offense. Instead of thinking, call an electrician, because nothing will help you through the forum, and you do not understand the principle of RCD.

    According to the diagram, a colleague is interrupted by an unknown-what wire (what type of network is it?) - at least a non-phase wire is interrupted, probably PEN, or the differential in this case disconnects this wire last and the connections first? If not, your colleague may have damaged many devices home garage.

    ... which does not change the fact that the whole installation is done wrong.

    In the event that the differential works, and one of the phase contacts "hangs" - the friend has a beautiful way of the mains voltage on the enclosures of the devices.

    Long to list errors ...

    Of course it's wrong. The circuits cannot be mixed since you are giving the work leads with before the off. the residual current device and the N / PEN wires (because it is not known, and you can not see the PEN chapter and the network layout is not written) you also have to give a differential before.
    And you have everything on one strip,
    Maybe instead of solving the puzzle yourself, call an electrician, you will lose a few pennies in your wallet, but you will have it done properly and you will gain peace of mind and the belief that it is done in accordance with the art.
    Because if you have it like in the picture, you have it there and it shouldn't be as it should be. Lots of deficiencies and errors in this installation of yours

    The author specializes in "shoe manufacturer". I assume it's about footwear ...
    By the way, you can get the "shoemaker's passion" when a shoemaker goes beyond the anvil and takes on an electrician, the same way if an electrician started producing shoes and asked how to hammer rivets and studs ...

    PS. And I know, I even have a hoof and high heels so far. Twine will also be found.

    elpapiotr then you have an advantage because you know how to solve the author's problems and you can sew shoes for yourself or whatever you do with them :D

    Of course.

    We have a lot of bugs:
    - the drawing shows the TT system
    - the description indicates the bridging of some PE with N
    - disconnecting "zero" from differential, etc.

    It's just trouble. And losses.

    What is the type of network TT :?: I doubt since there is zeroing in the sockets .... so where is the PEN chapter :?:

    This confusing drawing shows that you power the phase conductor of the old home installation without an RCD and the N conductor (or rather, in this case, PEN) goes through the RCD. By switching this wire without the RCD, you removed the fault in the house, but caused it in the garage.

    Where is the N wire to the garage? :?: the power supply is 4-wire 5-wire, this D16 should not be in your installation.

    You need a professional who can properly distribute and distribute the PEN

    And what are its values :?: why it is not connected to the PEN conductor :?:

    What kind of protector do you have, you can give the type or photo :?:

    As if by a miracle I have a single-phase power supply and this power supply cannot be mixed with an RCD.

    The drawing shows so. What is the actual network layout, the author does not know.

    If the fault is on the side of the circuit (probably this phase wire powering the house and garage), can I move it and connect it where? for a difference?
    or possibly transfer the power to the house and garage in front of the RCD and it will be like the old way. But there will be a three-phase power supply connected to the power sockets as shown in the picture.
    Power sockets are four-pin L1 L2 L3 PE
    As for the type and network systems, I may not know each other, but I have 3 phases and N connected to the house, in addition, PE is supplied "separately", which was not there before, but I did it on my own. Measurement hoop probes. The measurement was made by an authorized electrician who said it was okay.

    The fault is on your side. Don't touch it anymore, call an electrician (as soon as possible!), Because you will burn your radio and television equipment and people may get hurt.

    So I will. However, I will entrust this matter to an electrician.

    I like tinkering myself, but sometimes there are things that have to be done by someone more experienced.

    The N conductor running through the differential goes opposite to the rest of the power supply - phase from top to bottom and N from bottom to top ... maybe there is an error here?

    One of several errors in the author.

    At the first connection, N went from the top and also tripped the differential switch. Then I changed it. Or maybe someone is drawing it to me how it should look like?
