Planning electrical systems to be future-proof

I continued working on the topic last night and believe I have understood the basics. How does the wiring and connection in the network cabinet work in practice? Does an electrician take care of something like that?

You need to inform the electrician exactly where you want the connections installed in the rooms and any additional special requests if applicable. He will then lay the cables and connect them to a patch panel in the equipment room. For more than 16 cables, I would recommend a 19“ cabinet that houses the patch panel and a 19“ switch plus devices like [Fritzbox], [NAS] or similar. For fewer cables, there are also smaller network cabinets. Anyone can basically install the switch, and then only short patch cables need to be plugged from the patch panel to the ports on the switch.

If you want to use Power-over-Ethernet (PoE) (e.g., for the access points), it makes sense to choose a switch that offers PoE on at least some of the ports.

Do you already know how many connections you want to have installed in all the rooms?

It’s best to discuss this with the electrician.

If you don’t arrange anything specific with the electrician, he will usually just nail a patch panel to the wall and you’ll have to figure out what to do with it. It’s best to clarify everything with the electrician early on and also check whether it is implemented that way. Then you can also discuss where the performance limit is. (Wer den Netzwerkschrank bringt. Steckdosen in Netzwerkschrank anklemmen, Netzwerkschrank erden!)

Thanks for the feedback. I was basically unsure whether I should hope for a capable electrician for the integration, whether someone completely different does it, or if it is standard with the electrician.

To be honest, I did not expect to get so much help from you on my completely layman and poorly prepared question. Therefore, I refrained from digitizing and showing my handwritten sketches/preparations here. But I will gladly do that this evening. :)

Here is our distribution. In general, we have initially (?) only planned one connection and no double sockets. You would probably position a second LAN connection in the flexible rooms (office, utility room, children's room 1 and 2) at a different location, right?
Before I ask a few more detailed questions: What would you change? Where is something missing or where can we save a socket? For each room we also plan an additional satellite connection. We watch 50% linear TV and 50% streaming.

Untergeschoss
- Access point in the office (large symbol)
- 1x doorbell, 1x garage/wallbox, 1x office (possibly children’s room later?)



Erdgeschoss
- Access point in utility room and common room (as suggested by you), 3rd access point outside, next to the LAN socket for the awning/shading
- 1x utility room, 2x exposed concrete wall for TV, 1x outside for awning/shading



Obergeschoss
- 1x access point in hallway
- 1x child 1, 1x child 2, 1x bedroom

having to hope for a capable electrician

When unmotivated electricians meet unmotivated builders, this is what you get. He was capable, just unmotivated when it came to the network. The fact that everything is dangling around like that now really annoys me, especially since I look at the keystones almost every day, with which I want to fix it.

Therefore: force electricians to pack the CAT cables into keystones with enough leftover cable at a suitable free spot (!) and then take matters into your own hands with a 19" rack and make it look nice.
