Thanks for the quick reply!
First of all - Austria was no typo, I'm currently in Australia but designing the system for Austria, not that it matters because the electrical system is about the same here down under.
Secondly, I'm not sure why I can't put 2kW on one 10A circuit if I was in the 230V part of the world. I guess you were refering to the American voltages, and for me 2000W/230V = 8,7A is true or am I missing something (as I said in the other post, I don't have too much experience in that)?
And third, you answered both of my questions, thank you for that!
Let me just repeat what you said in my own words, to see if I really have grasped it:
Your 12x10A dimmer pack has dedicated channels for the 3 phases of the power service. The P1 connector serves channel 1-4, P2 5-8 and P3 9-12, each together with neutral of course.
So if I needed only 8 dimmer channels, I could simply not connect P3 to the dimmer but take it and split neutral as well as ground for another circuit with all of my lights that don't require a dimmer. I'm assuming that I run all the three phases through breakers as well as together with neutral through an RCD before the dimmer.
Or if I made the split and wanted to have access to the remaining dimmer channels 9-12 I could connect P2 to the inputs of channels 5-8 AND 9-12 which would give me power to all of the dimmer channels, but with only 32A available for all of the channels 5-12 together. Is this true?
I have not yet decided on my setup, but relying on only one 230V/32A three phase outlet is important for me. Therefore I could go with 6x PAR64 1kW on the first 3 channels (8,7A per channel, approx. 26A total), some PAR36 Pinspots or other small stuff on channel 4 and 16x PAR56 300W on channels 5-12 with 2 fixtures per channel (2,6A per channel, 21A total).
This would leave me the 32A of P3+neutral for the colour changers and Disco-FX.
I hope I got it right, a confirmation would be appreciated and thanks for your help!

BTW: This is for a mobile installation, but in a fixed setup where nothing is changed from gig to gig and nobody has access to the wiring. Electrical safety is important of course, but at the same time I don't have to cater for changing setups - I can be 100% sure that nobody touches the wirings I make.
