Yes. Older buildings had each circuit protected with their own current breaker (or fuses in really old boards), but with only the main breaker having been upgraded to a "modern" RCB. Therefore an earth leakage fault would trip that one and only RCB but not any other breaker, thus cutting power to the whole building.
