A fuse box (new consumer unit) is where electricity in your home is controlled and distributed. It’s important that you know where your fuse box is in case you ever need to turn the electricity off in an emergency.

The main switch, fuses and/or circuit breakers, and Residual Current Devices.

A) Main Switch – this allows you to turn off the electricity supply to your home. 

B) Residual Current Devices (RCD) these are switches that trip a circuit under dangerous conditions, and instantly disconnect the electricity.

C) Circuit Breakers – these are automatic protection devices in the fuse box that switch off a circuit if they detect a fault. 


Rewireable fuses have a piece of special fuse wire running between two screws.

When a fault or overload current flows through the fuse wire, it will become hot and melt. The melted fuse breaks the circuit, disconnecting the faulty circuit and keeping you safe.
