This article is pretty good.
Had a Landlord or Homebuyer Report & Received a Code For "Unsheathed Basic Insulation"? We Untangle The Mystery and Explain it in Plain English

Great read. Thank you.
So, everyone seems to be explaining the same thing which I now understand - regardless of a countries code, it appears to be a good practice.
In my apartment, I have plenty of exposed (unsheathed) cables hanging from the ceiling where we have not placed a nice lamp yet. So, if this were code in Austria, then it’s already a flag. Perhaps a C3 as the article explained as nobody is reaching up there to touch it without a ladder.
In my case, all of the unsheathed cables in their wago connectors are tucked away behind wood as seen in the photos. I’ve applied electric tape to not only identify which is which more easily, but to also further protect any cabling to accidentally become undone- which I believe the chances of that happening are slim to known as there’s no traffic up there. If anyone is touching anything it’s me in efforts of making it cleaner than it is.
Secondly, it’s surrounded by wood, so nothing is conducting electricity there should the unlikely event that anything come undone.
In conclusion, I believe it’s okay as it is, but I can be a bit obsessive over doing things correctly. So my take away from all your help is that despite the LNG connectors being close together, having them enclosed in a plastic housing unit so that no unsheathed cabling is visible, would make the wiring the most safe?
