Why does one outlet in the room not work?
Hello! After the complete repair (the builders were engaged), I discovered that one outlet did not work. Dismantled, there are three wires. White, blue, brown. There is no phase on any. When I close the blue and brown knocks the machine. In other combinations, nothing happens. Dismantled another, working outlet. There are also three wires, on a white phase. Connected white and blue. Brown is insulated. Of interest, the tester checked the white-blue produces 230V. White-brown is also 230V. I connect a light bulb; a white-brown machine knocks out. Maybe the builders killed that? Where and what to look for? Thank.

Hello! How can it be that there is no phase on any one, if the circuit breaks an automaton? A light bulb on white and blue hung? And do you have a machine gun or a difavtomat? As if brown was not earth. In general, there is such an option that they killed something, but you can only find a breakage with a cable tracker.
There is definitely no phase! The tester shows "0" in any combination. I myself am at a loss how this can be. Nevertheless, when a circuit breaker knocks !!!
Yes, the builders damaged something, maybe the phase. Perhaps there is a problem in the box. You never answered what kind of brown wire, if the phase is on white, zero on blue - maybe brown is the earth? Or you do not have grounding. You never answered your machine or difavtomat. If the second - then it can be knocked out on earth or leaks.
Unfortunately, I do not understand the types of machines. I can’t answer. It looks ordinary white, as they put it now. In the box, a ground wire (yellow-green) is present. So the land should be. I did not check on how it is connected. I did not want to spoil the repair, but I had to open the box. Thanks for the consultation.
