ᐅ Bus cables and power cables routed star-shaped into the distribution cabinet

Hello everyone,

we have a garden shed (one room) that has been unused for several months/years. I would like to move forward with the renovation. Originally, I planned to use the garden shed as a KNX test area.

Current condition:

• I’m not sure if it’s a good idea, but all power outlets/bus cables were wired in a star topology to the sub-distribution board. Here is an overview of the amount of electrical cables:

• I have a sub-distribution board with two sections:
• First section: 5 rows with DIN rails
• Second section: multimedia area

Questions:

• It probably wouldn’t make sense to protect each light or power outlet separately. Are there any terminal blocks or busbars where individual lights or outlets can be grouped before being protected as a whole? (e.g., Hager, Wago…)
• The same applies to the bus cables. I should have created one or two rings here. Now I have about 20 green cables in the sub-distribution board. Are there terminal blocks or busbars (preferably for the multimedia area) where the bus cables can be consolidated?

I will need to read up again on KNX and smart home as a test area and might have questions about components later on.

So if the list belongs to your garden shed, I am very impressed.
6 roller shutters?
Alternative TV position?
and so on and so forth

It’s like a tiny home, a small house. About 20sqm (215 sq ft). The previous owner often used the garden shed for barbecue evenings, with a kitchen, couch, TV, and so on.
For an alternative TV position, I installed two TV cables at two different spots just in case you want to rearrange the couch.
6 roller shutters = Well, there are 6 windows (2 of them gable windows). And 6 roller shutters for experimenting with KNX 🙂

There are double-level terminal blocks for DIN rail mounting, including versions for KNX systems (i.e., properly color-coded), for example from Phoenix Contact (PTTBS 1.5/S-KNX). They can be internally connected using jumpers. In my opinion (as a non-expert), this is the cleanest and most elegant solution.

No offense: but if you’re not familiar with these products, are you sure you want to wire distribution boards?

Hi,
I won’t be doing it myself; a licensed electrician will take care of that. I’m trying to learn more about it (towards KNX) and might handle some preparatory work.
Many years ago, I wired a standard sub-distribution board myself, using regular Hager QuickConnect terminal blocks. I didn’t know about these row terminals/floor terminals, but I’ve ordered them now.

Attached is an update of the wiring, and below are the initial controls or switches I’d like to implement.

1. Would it make sense to fit this inside a glass cabinet, or would that be too much—making a visualization or something else more appropriate?

2. The KNX setup in the cabin could be fully utilized or expanded, for example:

• A: Garden irrigation on/off / timed / smartphone-controlled
• B: One or two sockets next to it, on/off also possibly timed / smartphone-controlled
• C: For indoor lighting, maybe a motion sensor that turns the light on when detecting movement, with constant on by switch confirmation. I’d get a dimmable LED light (warm or white color is rather irrelevant)
• D: Same as C but for outdoor lighting and “not” dimmable
• E: A control motor for the heating regulation system

What KNX components would you recommend for the initial setup? And if it’s possible to cover points A to E at the same time, please include suggestions for those as well.

Best regards

Anyone has tips, or would that be too individual?
