Distribution board

In short
The metal board that holds your breakers — the heart of the home’s circuits.
Notes
The distribution board (DB) is where incoming power is split into circuits, each with its own MCB and usually RCD/RCCB protection.
During reno, electricians may add ways (slots), relabel circuits, or replace an old board. Label clarity matters later when something trips.
