Default Consumer Units with RCBOs

Apologies for resurecting this thread, but one final question. If I cannot have RCBOs at both ends of the garage supply, if I go for RCBOs in the garage CU and stick with am MCB in the main CU, does that MCB need to be outside of any RCD protected group or can it be RCD protected. There is a possibility that my garage supply cable can be re-routed under the floor and within cupboards or voids where none of it would require burial in a wall rather than the original plan which was to take it through the loft where at least 2m would have to be buried in a wall. I will not know how easy this will be until I lift a few boards and see.

Yes, No


Any difference between N and L current will trip an RCBO or RCD
