Grounding and grounding definitions in the floor plate
New building, starting repairs. Entering the apartment 3 wires (pink - phase, as well as white and green). White is bent, and a boiler is connected to the pink and green developers. In the floor shield, green is screwed to the body, and white and pink come out of the counter. I can’t understand which wire is zero and which ground.

If pink and white come out of the counter, then this means phase and zero. If the green in the floor plate is screwed to the body, then this is the earth. Probably, when connecting the boiler, they made a mistake. In order to avoid errors, it is better to invite an electrician to check that the connection is correctly made in the panel. In general, the earth should be connected not from the shield body, but from a separate grounding bus.
