Earth leakage explained
Our own house has a dual row Hager CU with 5 dual pole RCDs protecting various circuit groups, including one with just the central lighting and alarm. The reasons for this setup is that most RCBO are single pole, and N-E leakage (which occurs more often than you think) will cause the RCBO to trip, then the main incoming Type S breaker to trip.
