ᐅ Electrical installation without a sub-distribution panel

Hello!

I am considering routing every switch and electrical appliance individually to the utility room and installing a central sub-distribution panel there. I expect this to reduce installation effort and make future modifications easier...

Am I alone with such ideas?

Hello everyone!

Well, if I were to bundle many cables closely together in a cable tray over long distances, I would be concerned about loop impedance... but this is a rectangular 140m² (1507 ft²) floor plan with 4 rooms, where the utility room (I call it MFR) is centrally located.

By the way: I will be doing the work myself, so only the material costs are really an issue regarding the installation effort.
I want to combine the whole system with Alexa control and hope that this installation method will offer maximum flexibility.
Of course, I’m also worried that I might be overlooking something, which is why I’m asking you all...

A friend who is a certified electrician will connect the distribution board and carry out the final inspection.

Then just google “

Trying to implement a smart home in any way with a ‘serverless’ solution...

Which actuators should Alexa communicate with? Have you already chosen a system?

Before you start pulling cables, first plan exactly what you intend to do.

I haven't planned anything specific yet, but I have already seen Alexa-compatible surface-mounted switches that can be operated either conventionally or via Alexa.

Having a conventional setup or installation with surface-mounted switches is important to me. I would find it annoying to be able to control them only through voice commands.

Additionally, an Alexa-compatible blind control is important to me. But there are also switches for this, which can be operated as described above.

And why Alexa?

If you are going to find voice controls annoying sooner or later anyway. (Which will most likely happen)

Surface-mounted switches in new construction?

Why run all the wiring centrally when you can install the actuators locally at each switch location?
