Sockets or power strips

Briefly on the topic of networks. We usually install 1GBit capacity per cable. That's 128 MB/s.
Most switches do not have drastically higher total performance. Not to mention whether the source can even deliver the data in that quantity.

A real switch from €100 (so definitely not the Wi-Fi-TV-router-box from the provider) currently already has a gross transfer rate between 20 and 50 GBit/s. A few devices can pull full performance simultaneously.
Still, I agree with MillenChi: often you don't need that. And for current multimedia stuff, usually even 100 MBit/s is sufficient (especially since the Internet is not faster anyway).

But we also want to build somewhat future-proof. And I find it important that many devices can get, for example, 500 MBit/s Internet. (4K streams with surround sound, game downloads on PC and PS7...)
If at the same time the kids are "downloading the Internet," the husband watches BuLi via Sat-over-IP on the tablet, and the wife edits photos and videos on the NAS, everyone is happy if it all runs smoothly.

And one thing is clear: the data flow in the home network has certainly not decreased in recent years.

Therefore, I have 4 cables in the living room, 2 in the home offices, and one in the bedrooms. Additionally, one each where speakers are (or will be) and where Wi-Fi access points should go. And – simply because I can – fiber optic to the parental house! ;-)

Providing a socket and a LAN outlet for every device is clearly too many outlets on the wall for me.

No one is stopping you from plastering over empty boxes. The idea that being generous with the electrical installation automatically means you have to "decorate" all the walls of alternative locations with batteries of outlets is an unnecessary, housewifely fear fantasy.

In my opinion, every triple extension is a mark of Cain, indicating that a planner should have been beaten to death at that point for stinginess with wall outlets. An extension is basically a surface-mounted installation without nail clips.

In a multimedia scenario, there is usually a piece of furniture where a sub-distribution can be integrated. Seen that way, additional outlets are sometimes hidden inside that furniture – but: an outlet from which it is already known that it will be multiplied should logically be treated like multiple outlets. That is, the triple outlet in the wall should then be connected to at least two circuit breakers.

In a multimedia scenario

That means the triple socket in the wall must be connected to at least two circuit breakers

Well, as far as I know, there is no typical household multimedia installation that would require more than one 16A fuse. Fixed room lighting is usually not connected to the sockets behind the TV unit anyway (even a good 7.2 with 165W per channel only pulls 240W from the line).

And when I think that our 6-way socket hidden behind the TV (where a lot of small stuff like Apple TV / game console etc. is connected) would essentially be real sockets in the wall :eek:

Just counted; I would need 8 sockets behind the TV wall alone for power_o

In each room at least 2x Cat7 to a duplex socket, an additional one in the large rooms, so we come to 28 ports. At the "TV wall" and behind the workstation we have planned 4 sockets each, and otherwise in each corner of the room a double socket, at the room doors a single socket, on the long walls one double socket in the middle each, and in the kitchen of course a lot of sockets above the countertop. Especially here, distributors are absolutely not an option, everyone agrees on that.

Overall, I am inclined to say that the use of "distributors" indicates planning errors, but this does not apply to workstations or MM installations.

One can of course establish certain maxims. The question is what they cost. Having more than two sockets behind the TV is one thing, but prophylactically designing this analogously on other walls ... is uneconomical. Paying for 200 sockets and using 50 is a waste of money. Especially where power strips don't stand out at all, e.g., in the lowboard under the TV, where all the clutter disappears anyway.

A battery of unused sockets on the wall is also ugly.

As far as I know, there is no typical household multimedia installation that would require more than a 16A fuse.

I belong to the faction of "power amplifiers in the welding transformer class" who claim to be able to hear whether preamplifier and power amplifier are competing for power load.

Cable fires often occur due to cables under constant full load.
