Question for those in the know .... as a matter of interest, what is the right-hand ("Split Load") 3-module RCD? Is it perhaps wide just so that it can have 'output' terminals to daisy-chain the second RCD?
The neutrals are looped at the main switch and the "high integrity" neutral block.
The RCD's and MCB's fit on a similar basis to the old Stablok type, so the wider RCD picks up a live feed off the HI insulated busbar, then outputs the live to the busbar on the RHS.
