Wiring sockets, switches

Hello All

First of all:
We have the permission of the acceptance inspector to lay the cables and that was the question that concerns us and is currently open!
I myself am an electrician/electronic technician, but come from industry. Therefore, I am not familiar with the relevant standards in house construction. And the inspector is sick and unreachable, but time is pressing...

House wiring (new construction / prefabricated construction / timber frame).
What is currently the "state of the art"? We plan to separate the sockets and lighting.
Supply cable sockets NYM 2.5mm². Is it more sensible to have 2 branch lines in larger rooms, such as a living room with say 10 sockets?
And anyway, is it allowed to connect all these 10 sockets parallel on one supply line, or is a distribution box needed on site? We want to avoid this as much as possible.
Background: We want to lay the cables over Christmas and between the days. The acceptance inspector is currently sick and unreachable...

My opinion on the whole thing.
Wait for the electrician to tell you how he wants it!

That doesn't help much. We are already behind schedule. We can't close the walls as long as the cables aren't in. And it looks like he will be out for at least 3-4 weeks. It will probably even be the case that we need a new one. It might be that he won't be able to get back on his feet. Therefore, according to the current state of technology / general regulations, we have to at least complete the supply line and the wiring between the sockets. It was already clear and agreed with him that we can do without distribution boxes for the lighting.

Do you even have a plan about what you want where, how the light switches should control what, etc.? I think you urgently need to organize professional support and limit yourselves to the planning.

Who is responsible for procuring the cables?

Then find someone who knows the state of the art and plans the whole thing with you on site.

With the statements here, you have to keep in mind that, for example, a baker could also suggest something to you. Then you close everything up, and if things go badly, you end up opening all the walls again in the end.

Well, without being an electrician, one can say there is quite a lot to do yourself. If it's clear BEFOREHAND that you will find someone who does the electrical inspection and connects everything in the distribution board or main distribution board, then everything is fine. You really can't do that much wrong with common sense (oops, actually you can ;-)

I would reconsider the 2.5mm², unless it's 3x 2.5mm. With 5x 2.5mm² it gets tight in the boxes. But you will notice that at the latest in the first room. All consumers in the kitchen should be controlled separately with 2.5mm², that should be clear.

Do you maybe want to get smart later? Then separate cables or similar to every lamp. But of course it's tight to ask such questions NOW.

Installation zones can be found on Google.

Of course without guarantee, but own experience laying cables in 300m² of living space with very good success (after a year everything is still working). And I'm no baker either but an IT systems salesman.
