    I will ask...
    If in my installation of an unknown nature:
    I have two cables entering my house behind the meter, one of which is phase and presumably the other is zero (whether this is certain - I don't know, as the fact that one lights up and the other doesn't is supposedly not always an indicator)
    A differential has been applied to such cables, according to the instructions, and from this there are es spreading under rooms. So how do you organise the earthing there?
    The previous landlord did a trick such that he soldered a copper wire on the cold water pipe entering the distribution board in the flat. On the yellow-green rail.
    This rail is not connected to neutral, because it does not go from the flat to the cage - it only runs around the sockets in the house.

    Should I report this to the cooperative, since the yellow-green cable is not connected to zero?
    That is, there is no possible second distribution connection!!!

    And does such earthing make any sense at all since it does not participate in the flow/leakage from zero? That is, it is only suspended, connecting the cold water pipe and the pins in the sockets (the housings of the power consumers)?

    Will such earthing help anything if there is a fault?

    It can only possibly dilute something if there is voltage on the consumer housings!!!?!

    The best thing would be to additionally - despite the fact that it is buried probably without cover (water) - ground this tube with a pin...?????

    Do nothing but call an electrician who, after visual inspection and familiarisation with the installation, should dispel all your doubts.

    marekborcin, do you have a current protocol from the inspection of the installation? (I'm asking for a more detailed one, not the kind where a man from the cooperative examines 3 sockets, one in the bathroom and 2 in the kitchen). If you don't have such a report, and I suspect that you don't, I would start by finding such a man or lady who will do such a comprehensive inspection and you will know everything about the state of your installation. Since you have a problem in one part of the installation you may have more, especially if the installation was not done by an electrician.

    Are you familiar with network layouts? Zero (PEN) is only in a TN layout, but a TT layout is a completely different story and different requirements. Are you grasping this?

    Do you live in a house or in a block of flats ?
