Hello everyone,
In about three weeks, we are supposed to finalize our electrical planning on site. Unfortunately, our electrician is somewhat old-fashioned, which makes it difficult for me to collaboratively plan a future-proof electrical setup with him. Therefore, I am currently educating myself to ensure that the networking in our single-family home is fundamentally future-proof.
Basically, it’s about the LAN network... LAN wall outlets are relatively expensive, so proper planning is even more important.
About us:
- Mid to late 20s – couple without children. Planning for 2 children in the near future.
- Single-family house with a usable basement, 2 full floors, and fully equipped with concrete ceilings
- Utility room in the basement with air-to-water heat pump, ventilation system, photovoltaic system
- The router is planned to be located in the office on the ground floor
- The upper floor includes bathroom / bedroom / 2 children’s rooms
- No satellite dish or cable TV — we will use Internet TV exclusively!
Now, I am struggling to network our single-family home sensibly but as cost-effectively as possible.
I have the following questions:
1. Slightly off-topic: In the living room, I would like to have an in-wall conduit installed on the TV wall (the TV will be wall-mounted) so that no cables are visible. Is this sensible and affordable? I will get exact prices from my electrician if this makes sense at all. Would it also make sense to install power outlets at TV height? How do you plan the connections on your media wall reasonably? What should be considered?
Since we plan to use a Magenta TV box and thus IP-TV, a total of four LAN ports in the living room area would presumably be useful, right?
2. How many LAN outlets and especially where should LAN outlets be installed? Mainly: which cable? Is CAT6 sufficient?
→ Such a double LAN outlet certainly costs close to €200, so planning must be really sensible.
Is it really necessary to install 2 double LAN outlets in each children’s room? I always wonder: what is actually going to be plugged in there?
One port for the TV and one port for a multimedia device should be enough, right? So four connections would probably be overkill, correct?
The fact is: It will certainly take years or decades before our children actually use these outlets... Who knows what changes might happen by then? Therefore, could we not cost-effectively use empty conduits (empty pipes) instead?
Is it also possible to “branch off” from an existing double outlet afterward to add more ports for the room? What should be considered here? Or should we consider having an empty conduit prepared in another spot in the room so that a socket can be installed later?
3. How do you solve the “router problem”? Should the one router be placed in the office (ground floor) with LAN outlets in the existing bedrooms upstairs to ensure a stable LAN connection? Or is a router upstairs absolutely necessary?
4. How important are LAN outlets in the utility room? Should the router possibly even be located in the utility room? Because of the concrete ceiling between basement and ground floor, a second router would almost certainly be needed. How should this situation be handled with a basement?
5. What do you think about installing empty conduits for CAT cables in the kitchen / hallway etc. to enable later retrofitting? Is this relatively affordable in new builds?
I would appreciate any feedback so we can make the best possible plans 🙂

6mm² is already quite decent. 10mm² is often avoided because it is very rigid.
Why are you so sure the neighbors need 10mm²?
Your requirements with a few sockets, some lighting, and a small wallbox are not particularly high yet.
Ultimately, it depends on the length of the cable. That would be unfortunate, because the VDE (German electrical standards) require a minimum cross-section of 10mm² (about 8 AWG) for sub-distributions. And if you install some lighting, a few sockets, and a wallbox, that already counts as a sub-distribution.
I know this because I am also planning a sub-distribution in my shed, and my electrician immediately proposed 5x10mm² (about 8 AWG), saying he is not allowed to install anything smaller.

I would be quite surprised if every small garage, garden shed, or floor distribution panel had to be supplied with 5 x 10mm² (5 x 16 AWG) cables.
To me, this sounds like a misunderstanding of the term "sub-distribution."

xMisterDx24 Aug 2022 22:01I need to ask the electrician during the next conversation.
I mainly wanted to refer to "The electrician doesn't like doing that because 10² (10 mm² / 0.016 in²) is so hard to bend..."
PS:
In the end, it's always the same. Everything goes well, and no one asks.
If the house burns down and someone reads this, then there will be no money.
