Fuseboards
Does your fuseboard not have re-settable MCB's & RCD?
This technology exists to protect & save lives as well as protect the integrity of your circuits from burning out should an overload occur.
A FuseBoard, also sometimes known as a consumer unit, should be easy to find and is where the electricity in your home is controlled and distributed.
It’s important that you know where your fusebox is in case you ever need to turn the electricity off in an emergency. It contains three things – 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. You might have more than one mains switch, for example if your home has electric storage heaters. In this case you may have a separate distribution board.
B) Residual Current Devices (RCD) these are switches that trip a circuit under dangerous conditions, and instantly disconnect the electricity ideally under the minimum dangerous current to harm/kill a person,
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 (may be found in place of circuit breakers) – rewirable 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.
If you are concerned that your fusebox may need replacing, always consult a registered electrician.
