Circuit Protection ; Consumer Units

A consumer unit, or fuse box, is the main hub for distributing electricity in a building, connecting circuits to their fuses or circuit breakers. It protects wiring and devices by interrupting current during overloads or faults, reducing fire and shock risks. Modern units feature a main switch, circuit breakers, and residual current devices (RCDs) for enhanced safety by detecting electrical imbalances.
