[Solved] Changing the power supply from 1 phase to 3, apartment in a block of flats, old

Hello, here is my problem
Apartment in a block of flats, top floor, I bought an electric cooker. BEKO FSE57300GX max power consumption 7.8kW.
I want 3 phases I called SM* they said to send an application and I can do what I want because I will pay anyway.
Walking around the cage I checked the wires and they look like in the pictures.

1 - a can in the apartment.
2- here ZE** connects the meter.
3- hatch with wires on the floor below (there is a seal on my floor so I didn't want to touch it yet because I don't know the subject).
Looking at picture no. 3 I can see correctly that 3 phases are released in this vertical on the cage? and it is enough for me to report the need for 3 phases in my apartment to the ZE and they will connect it on my floor? (where the seal is) and I will be able to run the cables from the meter with 3 phases?
Is it somehow different and I will have to push another wire there (we are talking about those tubes from which the wires come out, picture No. 3) and pull it to my meter? :crazyeyes:

I hope all is well with the post.

There are 3 phases in the riser, but the cooperative has not written whether it will allow connection to this riser.

You have to write to the energy utility about new connection conditions and a new power allocation.
It is possible that under the conditions of the Energy Regulatory Office, it will demand that the installation in the premises be replaced with TN-S. (separate PE conductor).

Not for new conditions, but for an increase in power.

It's out of the question. Energy does not deal with such "little things". It's up to the electrician to do the work.
By the way, crap from photo No. 1 to be disposed of.

Oh, so they can answer me that they don't let me connect to it, okay, so the worst case is that I will have to squeeze another wire myself.
But if SM** agrees to connect to the riser in the cage, then ZE* will connect 3 phases to the meter and leave me some wire so that I can pull it to the apartment myself or what? (picture no. 2). Because 2 wires enter the meter and 2 come out. They will pull this wire there or will it be my cost?
The switchboard in the apartment will be new, on Sy

Power engineering has nothing to do with internal installation, It's the problem of the cooperative and yours. If the cooperative tells you to replace the headlights, your electrician must do it. If there is an exchange of wlz-tu, it would be good if it had a cross-section that would take into account the future needs of all recipients connected to it. In this case, you can take a "share" from the cooperative, but the cooperative can do it and charge you some % of the costs. From the meter to the apartment is your cost.

I have other experiences.

So the seal that is placed on my floor vertically on the staircase is the property of SM, right? and electricians from SM will have info. about that right? (it's about photo No. 3) because the photo comes from the floor below, my box is sealed ;)

And will ZE have any info. about what is in a given block (thickness and number of wires), what is the connection power I can afford?

The installation is in such a terrible condition that when applying for new connection conditions, you will probably have to replace the cable from the ZK next to the building, because this one, despite the fact that there are 3 phases, is old and the cross-section is too small. The installation is subject to acceptance, so before they connect the meter, they will check whether you have done it in accordance with the conditions. First, you also need to obtain the consent of the cooperative to work in generally accessible places, i.e. in the staircase. And then put everything back to its original state. Direct the first steps to the ZE, submit an application, wait for the connection conditions, show the electrician these conditions, let him do everything in accordance with the conditions ...

All right, I'm going to deal with the ZE tomorrow, and we're waiting for the sequel ;)

I am not closing the topic yet because I may need your help regarding this matter
Thank you for today and I'll get back to you when I get the info. from ZE. Regards

Hello
From my experience - first for permission to SM, it will be known whether SM has any requirements for the replacement of WLZ. After the consent of SM to ZE for power increase and 3f counter. It varies with administrators, but most likely you replace the wires from the pre-meter protection to the meter under the supervision of SM at your own expense, or MS will replace, but also at your expense, from the meter to the security in the apartment at your expense. ZE (Tauron) is not interested in what is behind the meter, because they require the "Notification of readiness of the installation to be connected, Statement on the technical condition of the installation" where there is a statement on the technical condition of the installation and the person signed under the statement takes responsibility.

What's more, in this case, the power industry is not interested in what is in front of the meter up to the exploitation limit, and this is most likely in the cable connector or on the stand/console terminals when powered by an overhead connection.

Slightly off topic, but related.
In the above case, the author probably "enters" the apartment, so the renovation of the installation is easier than if you already live there, secondly, the aluminum is asking for replacement, thirdly, he probably calculated the costs of changing from 1 to 3 phases in general costs.
But - in my opinion (and I know such cases too), changing the power supply from 1 to 3 phases in buildings where there is already copper with appropriate cross-sections in the apartment is not necessarily an expense that must be incurred when buying a cooker or hob, whether ceramic or induction.
I have an Amica 601IE3.464TaYKDpOg(XxL) cooker with a connection power of 10.5 kW since November 2011, and from the beginning of using the cooker it "managed" to overload the s301 b16A fuse maybe 4, max 5 times for a family of 4 with two children when cooking daily . Single-phase installation, so that two circuits go to the kitchen and on one there is a stove and lighting under the furniture, on the other the rest.
The author probably enters the apartment and there is no problem with such modernizations, but if someone already lives and wants, for example, to "transition" from gas to electricity and heard in the store that it must have 3 phases because the stove or hob is at 3f and draws a lot of electricity and the fuses will not withstand a the costs of changing the installation are more than the purchase price of the equipment, so I say: buy a cooker, if it is possible without major "damage" to pull a separate cable from the fuses to the cooker, pull it and use it, you'll see what will happen, maybe changing to 3f is not necessary at all.

Everything in the picture is in terrible condition. Absolutely to be replaced.
-Wlz for flat usually 5x6mm²
Then this pseudo-switchgear in the apartment is better to give a larger min 2x12 and, as the renovation of subsequent rooms, lead new circuits to individual rooms and fill new boxes
- I don't know what the kitchen looks like, but if you want to lead the cable under the stove (5x2.5), then immediately add a few circuits to the countertop for the dishwasher, fridge, etc. If the tiles are new, you can run them behind the cabinets in invisible places.
I have carried out such upgrades many times. Replacing the WLZ, setting up a new main switchgear and a circuit for the cooker is about PLN 2-3k with the material, but I would advise you to replace the installations and make more circuits in the kitchen right away, but you know other costs

There's no need to go to the cooperative.
He must obtain connection conditions from the ZE for the power he wants.
How much power will give ZE - is not known.

You are wrong again. He has to go to ZE with a piece of paper from the cooperative. Don't mislead people.

Just like it is possible that an asteroid will hit the Earth tomorrow.

Well, it's just the opposite. First SM, then ZE.

The idea of changing the connection was abandoned. The dishwasher and washing machine work at night, only the fuse box has been changed.
