TN-S can be made from TN-C.

Then show us how to do it. It is not for someone who invented and described magic letters so that others could swirl them freely.
I know people who TN can do with TT :)

I recommend page 39 in the book "Electrical installations in buildings" by professor Bruno Lejda, ed. WNT ISBN 978-83-7926-018-8.

Anyone can write books.
Paste this page or the diagrams posted there. It is difficult to argue about something we cannot see.

Unfortunately, I will not copy anything because on the 3rd page there is a warning against copying and publishing on the Internet "... And when copying parts of it, do it only for your personal use".
I want to modestly note that not everyone can write Here, the professor was assessed by prof. dr hab. Bogdan Miedziński and dr hab. inż Mirosław Parol, so everyone can take style trips, I would humbly refrain from doing so, because it has a negative connotation about the book, and it is not so. In my opinion, the book is excellent because it covers various network configurations, even DC. This book distinguishes this book from others by discussing requirements for special installations or locations, e.g. powering a barge, yacht basin, cruise ship, campsite, construction site, barn, etc.

To sum up, it is possible to change from the TN-C system to the TN-S system, it is a primer.

You can walk along an alley in the park ...

You can do installation in the TN-S system and power it from networks in the TN-C system.
So de facto it will be a TN-CS system including both the distribution network and the receiving installation.

Here you must also distinguish between systems where the TN-CS system will only cover receiving circuits, we are talking about a multi-family residential building. See page 368 "Electrical Installations" by Professor H. Markiewicz ISBN 83-204-2646-4

In this case, there is no longer any need to distinguish.

Well, if it's not difficult.

And modestly, I would like to point out that we have a free market and censorship does not exist. There will also be a recommendation - business must be spinning. Today you me, tomorrow you - that's how it works.
I know many rubbish books written by professors with the opinion of other leading experts. All recommended by SEP. At one time, I even pasted examples. Part of this, if I'm not mistaken, I pasted into "Matołek"

You are right in your opinion. The book may be interesting, it may cover many issues, but it does not mean that it is without factual errors.

I propose to change the primer and learn more about the description of network systems.
Also, please do not confuse the network with receiving installations.
I will repeat again:
TN-S Separate neutral conductor and separate protective conductor throughout the entire network system. Therefore, if there is no PE conductor in the network along its entire length, starting from the transformer, there is no question of TN-S. No matter what the professors in your book write.
Simply put, each new installation and final circuits are performed in the same way. Regardless of whether it is powered by TN or TT mains, we always have separate N and PE in the socket. The system of the power supply network is also irrelevant for home receivers.

Question for you.
Looking at the dismantled socket in the room, I can see three L, N and PE wires. What is my network: TT, TN-S or TN-CS?
