1-10V Dimmer and wiring question

I wanted all my CBUS units powered from their own MCB and a particular RCD.

Question is, if I have the 1-10V unit hanging off this MCB and RCD and connected to a 1-10V PWM LED driver whose supply and neutral is on a different RCD will this be a problem causing a trip?

Would the control circuitry in the 1-10V device be electrically isolated from the driver circuitry and not expecting to share grounds, have I explained this right?

Or to make this work would the cbus 1-10V unit have to be powered from the same RCD as the 1-10V dimmer it is to be connected to?

Not wired any 1-10V before, is solid CAT-5 ok, or bell wire or is T&E best?

 

maybe some bell wire would do it then or does this present the same problem as with cbus cabling having to be pink entering mains enclosures,

Suppose I could use some 1.0mm T&E or maybe that would become confusing. I'll ask my electrician.

 

Bell Wire/ figure 8 cable would be the best way, however your electrician will have to maintain segregation requirements within a switchboard. Using pink cat5 wouldnt be a good idea, nor would T&E, as it would be too easy to confuse them later on with the cbus network or mains cables.

If you are planning to run multiple 0-10v channels, you would probably be best going with a decent multicore cable, or if you're just running a single channel, then a double-insulated twin core cable, or speaker wire, would be a better way to go.
