What to do if the apartment has three-phase wiring, and a cable for single-phase is laid?

Good afternoon! They made the wiring and connected to a single-phase current. Now it turned out that the house was designed so that everything was a 3-phase current in the apartment. If you put a box with 3-phase current, all the wires also have to be redone? Cross sections for 3-phase current are different. How to be? The floors are already flooded, all wires are walled in them for a single-phase current.

    Hello! Who cares? Take one phase with zero. You will not have three-phase consumers in the apartment? Sections do not depend on the number of phases, but on the load! Before developing the wiring project, it was necessary to determine the number of phases, the presence and the grounding system. If you want to organize a three-phase input, you can arrange the rooms in phases. But if you have a wiring loop from room to room - it will not work. Call a qualified electrician for help and don’t do it yourself if you don’t understand basic issues.
