    Hello, I have a question, can you do as it is in the picture below? I am going to set up separately and I have a 2-core cable (phase and neutral) pulled to the house, there is no grounding, so I thought to do it as in the picture and here is my question, is it possible to do as it is done in the sockets that I make a bridge between neutral and ground ?

    Legend:
    blue color: terminal block for neutral conductors
    green: terminal block for earthing conductors
    green-yellow colors: ground wire

    I wonder if you wrote this consciously ... Your statement suggests TT power grid (which I doubt).

    And this statement suggests that, however, the TNC, so you have L and PEN (or zero) power supply.

    Find out if I'm wrong - if I'm wrong.

    If you have a TNC network system (neutral-protective-PEN conductor), you can do so. You add differentials to it and you will become the owner of the TNC-S network system.

    I just don't know if I have L and PEN power supply. How can I check if I have it?

    Oh, and back to my question. Can it be done as shown in the picture?

    You have not specified what power network - without it, there should be no discussion, because we create a multi-topic thread ...

    If the TNC, then the PEN conductor is connected to the green strip, and your "bridge" (cross-section not smaller than the PEN) remains. According to the principle, protect first - power later.

    I was looking on the electrode but I did not find how to check if I have L and PEN power, how could you help me. I will be very grateful.

    Call the utility company and ask.

    because I now have a bridge between the neutral and the protective one in the sockets in the kitchen and bathroom, so I think I have L and PEN power supply.

    The reset bridge suggests installation in a TNC network system (very likely). Look here-

    if I have a bridge in the socket between the protective pin and the neutral contact, I can do it as in the picture in the first post?

    You can, it's only better if you do TNS right away.

    only where I will attach the protective wire, since in the staircase I do not have a 3-core cable, only 2-core.

    There is no need to guess !! call ZE and ask in what network system your installation is, no conversation makes sense.

Topic summary

The discussion revolves around the feasibility of connecting grounding to neutral in a residential electrical setup using a 2-core cable (phase and neutral) without a dedicated ground. Participants clarify that if the power supply is a TNC system (where neutral and protective earth are combined), creating a bridge between neutral and ground is permissible. However, it is emphasized that the user should verify their power network type (TNC or TNS) before proceeding. Suggestions include contacting the utility company for confirmation and ensuring that any modifications adhere to safety standards. The conversation highlights the importance of proper grounding practices in electrical installations.
