Who should fix? One phase is missing

Hello
Firstly, I apologize if I posted the question in the wrong forum


I have a private apartment in a 24 family block. We have established a housing association and signed a contract with a property manager who conducts all kinds of inspections, maintenance, administration, breakdowns, defects, etc. for which he charges an appropriate fee depending on the usable area of the apartment.
For a few days now, one of the three electrical phases has disappeared in my house. I privately called an electrician who reviewed the installations in the house and the main one in the corridor and came to the conclusion that the current on one of the phases no longer reaches the pre-meter fuses and unfortunately I am forced to report the problem to the building administration because he himself can no longer help and to do.
So I reported the matter to the administration, which automatically sent me to the power company. They, however, immediately informed me that such faults are not their responsibility, and the only thing they can do is to come and put seals on the devices that were possibly broken during the repair, and that's it.
My question is who in this case can or should take care of this problem.
Another electrician, perhaps the first one did not want to interfere with other rail protections, etc.?
The administration responsible for the care of the building and the common areas of the tenants?
Maybe an energy company?

what does pre-meter fuses mean? in front of your meter? (then the building administrator calls an electrician with whom he has a contract) or in front of the WLZ meter - then the energy company - the community may demand compensation for failure to maintain network parameters.

Yes, I have three fuses in front of my meter and one of them no longer has power. And at this stage the private electrician said thank you, it's a matter for the building administration and the administration redirected to ZE, who also ignored me.
However, what you write confirms my belief that the administration should take over the matter here and possibly inform me what it does next and how.

Exactly. The probable cause is the activation of the 1-phase protection at the building connection.


Call the administration and don't be fooled

So I will...
as for breaking this protection, it's a strange thing because the current can appear for 2 minutes and disappear.

You can "break" a window or teeth.

If the power comes on and off, it indicates a fault in one of the connections, not a tripped protection.

The fault may occur both in the ZE network and in a shared installation managed by the administrator of the facility.
You have checked your part of the installation.
Now it's the manager's turn, who will do the same in his part and diagnose whether the disruption is on his side or in the provider's network.

This is some contact loosening in the distribution system of the building itself.
The case of the building's electrician-conservator.

Up to the exploitation limit - this is the scope of the power company. Where is the border? The manager probably knows that.
From the border to the premises - it's a community thing.
In the premises - yours.

The tenant or landlord also knows/should know.
It is written in the contract with the DSO. The contract is between the tenant and the supplier.

Call an electrician from the bulletin board in the staircase.
I'm sure there's an electrician there.
He's an electrician who rummages in the building's main switchgear.

But he doesn't need to know where the boundary is in the object

If it is a 24-family block, it is unlikely that only one tenant will use this one phase. If no one else reports the problem, the fault should be fixed by the property manager. The electricity supplier has nothing to do here.

I would strongly bet on the problem between the rail bridge (vide distribution block) -> pre-meter protection or the state of the pre-meter protection was wrongly diagnosed. If the meter is electronic, it is worth looking at what it displays (the error will be visible to the naked eye. The fact is, no supplier or operator will disassemble such a cabinet in its first part to find a fault. This is not ZK. An electrician-conservator is responsible for the solution ( assuming that he has an idea about the prefabricated element or, as a last resort, has technical documentation for it).
