Fuseboxes Explained

Fuseboxes explained

Your Fusebox – the fusebox or consumer unit should be easy to find and you should  know where it is in case you ever need to turn the electricity off in an emergency. It usually contains three things and is used to control and distribute electricity around your home. These are: 

A) Main Switch – this allows you to turn off the electricity supply to your home. You may have more than one mains switch, for example if your home has electric storage heaters, in this case you will have a separate fusebox.

B) Residual Current Devices (RCD) these are switches that instantly disconnects the circuit when it becomes dangerous. If your fusebox one or more RCD, test them regularly by pressing the “TEST” button. This is important because some of the mechanical parts may seize up and not trip when the circuit becomes dangerious.

 

C) Circuit Breakers – these are automatic protection devices in the fusebox 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.

Fuses  (not on the image, may be found in place of circuit breakers) – rewirable fuses have a piece of special wire running between two screws. When a fault or overloaded current flows through the fuse wire, it will become hot and melt, this disconnects the faulty circuit from the electricity and keeping you safe.

If your fusebox has a wooden back, cast iron switches, or a mixture of fuses it is likely that it dates back to before the 1960s and may need to be replaced.
