Consumer unit also sometimes called a fusebox, need to be easy to find and is installed to provide the control and distribution of the electricity in your home. Every householder need to know where fusebox is in case need to turn the electricity off in case of fire or other emergency. It contains three things – the main switch, fuses and/or circuit breakers, and Residual Current Devices. Main Switch allows you to turn off the whole electricity in your home. Residual Current Devices (RCD) is a switch that trip a circuit under dangerous conditions, and instantly disconnect the electricity. Circuit Breakers are automatic protection devices that switch off a circuit if they detect a fault. They are similar in size to fuses, but give more precise protection. When they ‘trip’, you can simply reset the switch. But make sure you correct the fault first.
