Renovating Kitchen: 3-Phase Cable Distribution, Induction, Dishwasher, Oven and 230V Socket

Hello

I am in the process of renovating the kitchen and my distribution of receivers will change a bit. I have a few questions about this:
1. 3-phase cable - normally the oven 230, induction 230 + dishwasher was connected to it.

Now it's supposed to be induction + Dishwasher.
Induction - maybe I would finally connect it to 2 phases. Dishwasher - standard -230

I've seen mini switching stations in building warehouses - for a 3-phase socket + 1-phase socket. Or maybe there are switchboards for a 2-phase socket (for induction) + 1-phase socket - for a dishwasher. Is such a separation of phases on a common neutral and grounding a correct action?? Are additional protections applied in such switchgears? I mean something like this:

The second thing is to connect the oven. In the place where it is supposed to be, there is a socket 230.
But here the fridge + microwave + this unfortunate oven is to be connected. It is known that the oven will not work together with the microwave - maybe with a few exceptions - but does such a connection make sense.
Will I have to pull another 230V section unfortunately?

Or is there any other solution?

First, what do you mean by "2 phase socket"?
Secondly, so many devices on one circuit is a bit of an exaggeration, unfortunately you will have to lead a new circuit to the kitchen.

The unprofessional term is my 2-phase socket. Generally, I mean connecting the induction not to the cube, but to some kind of socket - e.g. 4-pin - 2 phases + zero + earth - if they are.

I found one more interesting thing in the kitchen - a can - and a grounding wire in it - a cable comes out of it and comes out of the can and wraps a pipe with hot water - rather not to insulate this cable :)

Of course, I'm interested in the sense of such an old-fashioned solution - whether it can be improved in a simple and correct way. Or maybe leave such a PRL solution as a history museum.

This is not an old-fashioned solution.
This is an equalizing connection that you should not touch.

The two-phase board should be connected straight to the box or through a 400V "power" socket, where you leave one phase contact unconnected. Out of curiosity, what cross-section has the already routed cable and what protection has been used?

And all the rest too.

It's like this:
Connecting to the tube - I should probably improve some clamp - a wire wrapped on an old tarnished tube is not a professional solution.

3-phase cable - what cross-section - I have no idea - black thick cable (like a finger) 5-wire :)

And the security - what kind of security are you asking about?
Earlier games with electricity were made by an unspecified person - and now that I have thrown everything out of the kitchen, I know what is there - but I understand that there should be a fuse when connecting the induction there?

I will ask again - if I use a mini switchgear - for a 3-phase socket - with one free pin. Can this third phase be used for an additional 230V socket on a common neutral and ground?

Added after 5 [minutes]:

Back to the type of 3-phase cable. I think it's 5x2.5

either zero or neutral and protective. Tell us friend what network system you have, how thick the power cord is and what protection is installed on this circuit.

Ok - neutral and protective.
Circuit breaker S - 193 B16.

What's your network layout? TN/TT?

Unfortunately, I don't even know how to check it and rather I won't check it at home.

It is a block of flats probably built 20-25 years ago.

Since there is a cable terminated with connectors without a plug, this device cannot be connected to the installation using a socket and a plug.

Here you go, an example clamp --> https://onninen.pl/pl-PL/obejma-uziemniajaca-...wany-tasma-braz-5057507-obo-bettermann,HDF524

Ok - the induction is done
Dishwasher - can it be easily connected to one of the phases of the cable.
I do not hide that earlier each phase was on a different device - on induction (for 1 phase) + oven + dishwasher.

Neither one nor the other, just some kind of partisanship.

He definitely can't stay like this.

Sure not. There are grounding straps for this, which were probably not at hand during assembly.
But it can also be as Zbich writes. However, it won't work from a distance.

I strongly agree with the above statement. Especially since I saw such solutions probably 25 years ago.
Just what to do with it.
You can see that this box with the protective cable has been specially placed there only for this one cable.

I have another aesthetic question.

Since I already have this cable from the wall, 5 cores and 2 phases are to go to induction and 1 to, say - a standard socket - can it be somehow aesthetically connected and not with cubes that will be closed in a box. In addition, according to the rules, there should still be a differential - maybe there are some ready-made small boxes / switchboards as in the first post - a combi socket. Something not big that will sit behind the furniture - behind the drawers. Even if the differential broke, you could turn it on.

This differential is to be in the switchgear and cover all circuits in the apartment. When was the circuit to the oven conducted?

So I have something like that Once someone mentioned to me that the differential should be with induction - I did not delve into the topic and induction worked for 8 years.

And when it comes to the oven - it was always connected to 1 phase from a 3-phase.

Now the plan is to connect to a normal socket (change of position) - only that there is probably 1.5mm - Will I have to run another circuit under the oven in this case?

The wire is yellow-green, it does not mean that it is protective.

In this installation, I happened to have it as a phase in several sockets - it's like connecting sockets in series at random and yellow-green becomes a phase .... And in one of the sockets the phase was on the pin.

The text is just fun.

What about common N?

What's fun about this text?

As for the N - Well, that's what bothers me too.

The fact that it is a serial connection only in your opinion, these sockets are 100% connected in parallel.

I would not exaggerate with these percentages - but if you are so sure of it, please explain - I take out the socket 1 in the room - and the tick has no electricity in any other. It would be nice if it was a parallel connection and the sockets were connected separately to the main "mainstream", but unfortunately this is not the case - someone was happily running other wires from one socket to the next sockets, then broke through the wall and continued happily in the next room. For the latter to be returned to the counter, it would be a problem - but in Poland this type of connection is not used? (but here I'm not sure - or rather, I don't know).

There is no such thing as an earth electrode through a pipe!

They never existed! Do you know what a switchboard is?

Ad-rem - separate circuits for "induction", oven and microwave (all approx. 2 kW), especially at the renovation stage! The so-called sockets "two-phase" does not exist. No diagram, wire cross-sections, protection characteristics, network layout, SPD protection of equipotential bonding...

I remind you - Electrics, Installations and Networks section. -> read the description of the section.
