Why is there a voltage of 230V between zero and ground?
Why is the 230V voltage on the same outlet in the apartment on the wires zero (blue) and ground (w / s), and there is nothing on the phase wire (brown). When connecting even a weak load to these two wires, it is in this outlet that the machine knocks out. In other outlets and in general in the electrics, everything is fine. What is it? How to fix?

In this case, the reason may be in the wrong connection of this wiring line. It is necessary to check the correct connection of the cable in the junction box or switchboard. At the same time, if the machine knocks out when the load is turned on, this may indicate a malfunction of the circuit breaker of the given wiring line or damage to the wiring line - it may be short somewhere and this is manifested when the load is turned on. In any case, it is necessary to check this part of the wiring that powers the given outlet, starting from the machine and ending with the outlet itself.
