Hello everyone,
I now need to connect the recessed spotlights together. Is it possible to wire the spots as shown in the first image? Or do I have to follow the second layout?
The conduit would be the Fränkische FFKUS 25. If that’s not sufficient, then the 20 mm (0.8 inch) version.
For the cable, I would use NYM 5 x 1.5 mm² (5 conductors, 1.5 mm²).

Everything should be controlled via DALI.

Yes, it can be done. You just have to hit the right spot and use a proper rotary hammer with the appropriate drill bit.

You naturally have to hit the pot
Drilling from underneath helps with that

Sometimes luck is so close at hand, but it can be hard work.

And the whole project fails if ventilation ducts are poorly documented within the ceiling.

I don’t understand this now either. If they are inside the ceiling, the boxes would have been visible when they were installed. Okay, of course, some fool could have placed things ON the boxes. That’s the reason for the procedure used by our construction supervisor: everything goes onto the rough subfloor, and only steel and concrete go into the ceiling.

In our case, those come only after the ceiling has been poured.
So says the general contractor.
