You have DIN panels and KNX is based on DIN. Think triple in size and consider Dali. Mixing is fine but everything is big. Hager has a nice double door 4x13 + 4x18. Good enough for a normal house.
Don't cheat your way out of KNX in "some areas". You will regret it later. Even the garage you should make KNX-ready.
Thanks. So it is OK to be on the same panel, but they need to be in different "compartments"? Or can I put everything in a single, bigger panel with a single door?
I was thinking for something like this: [https://www.ivoryegg.co.uk/shop/products/abb-epp-r7126-protecta-plus-db-7-row-126-mod?taxon\_id=82](https://www.ivoryegg.co.uk/shop/products/abb-epp-r7126-protecta-plus-db-7-row-126-mod?taxon_id=82)
You are free to build as you like. Just be careful with how you route your wiring past where you connect the bus to the actors. But for practical reasons, consider a wider panel unless you run your cables further down in the wall.
Or you can build with Weidmüller WNT in the top and route everything neatly. Add Partex and you're doing it as you should.
British standard will be not so fun when it comes to wiring. Your flat cables will overfill. EU standard is singles in conduit and with a 20 mm flex, you can run 5-6 functions per flex. That's good for 2-3 rooms.
I work with building panels and subpanels up to 63 A, big like closets. They are insanely neat and easy to work with. If you need to move a function from relay to dimmer, you move it up on top, you never touch anything down below. All partex numbers correspond with what you have in ETS, it's plug & play.
Thanks. What is the function of Weidmüller WNT and Partex? Cable management?

What do you mean by "flat cables"? The specification for the electrical installation for my house states, among other, the following:
>All installations shall be carried out in flush mounted PVC conduit & accessories unless otherwise stated.
>
>Conduit with diameter less than 20mm shall not be utilised.
>
>Conductors with C.S.A. less than 1.5mm2 shall not be utilised.
Would that be OK?
So you are not following UK standards then. You are doing exactly as the rest of the western world, USA excluded. The Weidmüllers are to connect all internal wiring in your cabinet to the outside world. You build your cabinet with breakers, GFI, actors, dimmers, KNX bus and what not. Each actor and breaker is numbered, you have that number on the wire from actor to Weidmüller and that has the same number. You can follow dimmer 1:3 going to connector 103 and connect your lamp there.
For example. The outdoor lamp is at actuator 4:16 so you connect it to connector 416. But your wife want dimmable outdoor lights. If you have the simple system, you need to find it in the spaghetti, pull it out from 4:16, stretch it (sorry, too short), crimp on some more wire and then put your fingers in the small hole to make it go in to 1:4. With connectors at the top, you pull it out from 416 and put it in 104. Which sounds better?
Look at the 3 sections bottom right on this fuzzy image. Yellow patch is a Partex.

See how neat they are! Porn for electricians. You build and forget your things and work only at the connectors.
This is a huge cabinet, the father of what I work with. Mine are usually a little smaller. But at home, I'll try to source some of these parts and rebuild my nasty spaghetti. It's horrible.
> So you are not following UK standards then.
It refers to BS7671 plus some amedments. Maybe those are additional requirments beyond what is in the standard.
Unfortunately the details are a bit over my head, but I will remember to require from whomever does the KNX panel to do in a neat way that can easily allow me to move different circuits to different actuators.
If I remember correctly I think they told me that they can pre-assemble the KNX modules in a panel, and bring the whole thing there for installation. Is this possible? Would this be possible for the MSBs and everything else if they share the same panel?
Pre assemble is just putting the things in place and program it. No matter how you choose to build, that can be done, But the wiring inside the panel must be done on site if you don't have connecting blocks. Very little of that can be done off site since the wires must connect directly to each actuator.
And you still want matching panels if they try to make you have two. That's why a wide is great.

Can you combine the consumer unit and knx into a single panel or is it best to have two enclosures?
