A consumer unit is the main domestic distribution box that takes the incoming supply and distributes it to final circuits through protective devices. It combines a main switch (or RCD main) with MCBs, RCBOs, or RCDs to provide isolation and protection for a single dwelling, and is commonly built to IEC 61439-3.
