Aye, the thing to remember with RCDs (RCBOs, RCCBs etc) is that whatever current flows down the phase for the RCD must return via the neutral side of the same RCD.
If any it is mis-wired so either more or less current flows in the neutral than in the phase then it will trip.

It's been spelt "d o w n" since 1st May 1707....isnt this case with everything what flows down the phase must equal and balanced back doon the Neutral
