Hello everyone,

The house is slowly but surely taking shape. I am currently discussing the final details regarding the electrical work with the electrician.
One question that came up is where I want to have switched outlets installed.

Background information:
Smart home system with Busch & Jäger.
In every room, there is 5-core cable as well as bus cable.

Do you have any tips or ideas from your own experience on where you would place the outlets?!

Thanks and best regards

Even at a height of 3 meters (10 feet), everything belongs to us, and the Minister of Education is also decorating up there.

We have wired every outlet with five conductors in a star topology, allowing for quick retrofitting of switchable outlets.

The switchable outlets I use very frequently so far are:

- Portafilter machine, for preheating
- Floor lamp in the living room
- Air purifier in the kitchen
- Decorative lighting (Christmas)

The rest are used more sporadically.

In the living room, children’s rooms, and bedrooms, we have the very left outlet switchable, in case you want to connect a floor lamp or something similar. There are also outlets in the window reveals at some windows. All exterior outlets are switchable as well, and later grouped as needed in the visualization. I initially considered this for the kitchen, but on closer inspection, it didn’t really make sense to me. Just in case the idea comes up: I wouldn’t make the TV switchable, as most modern models don’t like that. There are much better solutions for multimedia devices.

Overall, I think switchable outlets inside are overrated, unless you really fill the house with floor lamps. I prefer switching actuators with power measurement for critical devices, where switching is just a nice bonus. If you set this up smartly in the distribution board (or have it done), you can still add it later if you find you’re missing something (which is pretty much guaranteed). Switching actuators can be retrofitted quite quickly if there is enough space. On the other hand, switchable outlets make sense in the laundry room or utility room, if you have one, for the iron, assuming you designate an “ironing spot.” That way, no one ever forgets to turn off the iron, and thanks to power measurement, it can automatically switch off after, say, 60 minutes. Plus, with logging on the server, the wife can nicely point out how long she spent ironing while the husband just lounged around 😀 😀 😀 😀 😀).

Great. Many thanks for the detailed description. What exactly are “switching actuators with power measurement”? Could you please explain that? How can I picture it?

The actuator not only switches the load (e.g., an outlet with a device) but also measures the current on the switching channels. This way, you can, for example, check whether your washing machine or dryer is still running and receive a notification when they are finished. If you don’t have a separate media controller, you could also use this to detect whether a TV is on and, depending on the position of the sun, automatically close the blinds or dim the lights in the evening. There are hardly any limits to the possibilities.

Uh, each outlet with five wires? What’s the purpose of that? Either it’s switchable or not, but in both cases, only three conductors are needed. Or do you want three-phase power everywhere (possible)?

We have three-wire outlets everywhere; each outlet receives one wire.
If it’s not switchable, the wires are bridged at the terminal blocks. If it ever needs to become switchable, I don’t have to unscrew the outlet—I can easily change it at the terminal blocks.
The additional material cost is minimal.
The standard setup is two non-switchable wires and one switchable wire.

By the way, we went ahead and installed all five wires anyway; a few extra dollars for copper don’t make much difference.
