I would tend to go for double-pole RCBOs on all circuits.

Good way of ending with a mile-long CU & higher cost.


And greater protection and the lot not tripping out only that circuit.

Single pole RCBO devices would offer the same level of fault protection

That is total drivel.

I can only assume

Some device that isolates the L & N when it activates must offer a higher
level of safety.
