Ring Connection in Electrical Installation: Boxless vs. German Socket Wiring Technique

Quote:

... "N" is individually grounded by dividing the main switchgear with the TN-C installation.

There is no N conductor in an installation configured in TN-C. There is also no PE conductor in this system.

And we don't ground any PEN breakpoint in TN-S, buddy macco1987 .

... so what's the harm from the last socket, let the cable go to the switchboard.

For what purpose, buddy kidu22 ? What will be the effects of this " which is harmful "An electrician should know this, and he should consider all of them behind and against rather than recommending a solution while asking which is harmful .

Lord ele_pp so the rated voltage was 127V? And zero, because that's what it used to be called, was taken from water pipes?

In an AC network, the concept of rated voltage is rather not used. This is reserved for receivers. There are phase and phase-to-phase voltages in the networks.

NOT. The phase voltage was this value. Such solutions were popular in the USSR for a long time, some devices from this country (TV sets) had 127 / 220V power switches.

Hello, buddy kkas12, not always people have the means to replace the installation and the old zeros (PEN) like to get hot, sometimes you have to solve the problem by switching from TN-C to TN-CS ...

And what do we ground then in TN-S? PEN? It is repeatedly grounded, N? is bridged with PE and together they form PEN, so what?

You are responsible for grounding the PE protective conductor (or the protective-neutral (PEN) conductor in the building. Regardless of where the PEN has been divided. Only that much and nothing else. So no matter if it is a TN-C, TN-S or TT system.
And what the connections inside the system look like is a different question.
It is up to you to ensure the safety of the user.

And don't play economist.

Well, they were split in the connector, not in the RG, and what should I ground the PEN and then the bridge to N? You ground at the partition point and you have an earth electrode and an individual one at PE and PEN

Since the PEN was senselessly divided in the connector remote from the building, you have to ground the PE in the building anyway and nothing else.
And what has been done in the joint is neither your business nor your business.

Well, the connector is just next to the building, so there is no wastefulness and there is a dog buried here, the earth electrode of the point is not pointless if the division point is next to the building, on the facade and close to the Central Statistical Office, as in commercial premises where there is a separate installation and a different utility tariff ...

What does the Central Statistical Office have to do with the topic?
Point buddy to the record that orders the PEN split point to be grounded.
You won't.
So don't write what makes sense and what doesn't.
And you are about to ground the PE in the facility at the beginning of the installation. And what does the tariff have to do with it? I do not know.
So please explain.

And don't bend the facts arbitrarily for your interpretation.
The standards clearly define everything.
And it is not the grounding of the PEN or the grounding of its split point that is important, but the grounding of the PE and equipotential bonding.
And how wrong is your way of thinking and what effects it brings you can find in this thread https://www.elektroda.pl/rtvforum/topic1895038.html

My friend, the presented thread concerns the point of separation distant from the building and the fact that the earth electrode in this case is something ridiculous, we all know for a long time! THIS IS TRUE AND CLEAN LOGIC !!! However, my post is about a building where:
- there are cooperative flats with TN-C installation
-on the ground floor there is a commercial space where there is a SEPARATE installation already TN-S
- a box with a meter, in which there is a division point, is mounted on the facade of the building right next to GSW (not the Central Statistical Office)
- PE is grounded in the terminal
- so what is the problem?????????

The problem is, you don't know what you're writing about.
Whether or not a PEN grounding point (not a PEN split point) in a connector is necessary is neither your business nor your problem. The connector is the property of ZE and they decide whether or not to ground the PEN conductor. So don't write that this is ridiculous.

Explain the phrase

Quote:

PE is grounded in the terminal

And do not write what is and what is not the topic of the thread.
Stick to the specifics, not what you think right now, because when you see it, you get confused.
And don't "scream".

Conductor terminal, PEN division point from which the division of conductors into PE and N is derived. The one from which the GSW connection is made
All the time I mean the fact about the earth electrode of the partition point, close to the building, It is true that it is not ordered, but is it a mistake ???? If so, the energy industry does not know what it is doing, such is the conclusion ...

Energetyka is not a legislative body in Poland and does not constitute a law.
Standards apply to them, as do us.
However, the reason that various power plants ordered in the TWP to conduct LLs with PE and N already separated in the cable connector is the not fully thought-out provision in the Regulation requiring such implementation.
Today, however, more and more ETs are departing from such a dictatorship. Do they break the law by following logic and rules?
In my opinion, no, because stupid records should remain dead records.

And stop writing about grounding the partition point of the PEN, because nowhere will you find such a prescription.

In your case, you cannot ground anything unless the main connections are made in the building.
Because your grounding is nothing more than local connections.
So if, however, the PEN has been grounded and the main equipotential bonding has been made, then the local connections are rather the priority and the connection (grounding) of the PE rail to the GSW is not important.

And we should finish this thread here, because it has no real connection with the topic ...
Thank you for expressing your opinion to my colleague and best regards ...
