No Electricity in Kitchen Sockets on Refrigerator Side: Identifying Cause & Solution

The sockets are in a loop from here, four wires. It is actually one and the same circuit. Normalka in blocks built under the communist regime, I have this in my flat myself and recently I changed from old sockets to new ones with pins in the whole flat. There are no protective conductors here, there were sockets in the kitchen and bathroom with the plug originally connected to zero. I did the same in the whole apartment, i.e. I have sockets with a pin everywhere and I connected this pin to zero.

You need to connect the wires by color to each other and to the socket to keep the loop. You fasten both blue ones together and plug them into the socket, similarly to the black one. Then you take a contract for energy supply and you are looking for the magic abbreviation TN-C, it will be around parameters such as the contracted power and the main fuse. If there is something else, like TT, then do nothing! If there is TN-C, connect the pin in the socket with the blue wires (zero), just check if you sometimes have no phase there because various things have already happened. 230V is to be only on black.

It will be fine, this is how I have all the sockets connected at home. And in the previous one you had the wrong thing that you wanted to remove the two wires connecting the two parts of the socket to each other. The socket might work if the loop is properly powered from both ends, but the loop itself would lose continuity. And this is what the point is not to disconnect it anywhere, because then each socket gets power from both sides, with two independent 2x2.5mm cables. This gives greater reliability and safety, the short circuit loop impedance in the circuit decreases, the cables heat up less, in the event of a cable break somewhere, e.g. drilling, the circuit continues to function properly and so on.
