Homesafe Electrical & Security can provide a free quotation to replace existing rewireable fuseboards with Consumer Units containing Minature Circuit Breakers (MCBs) & Residual Current Devices (RCDs).

These consumer units have built-in 30mA protection for the use of electrical equipment outdoors & easily re-set circuit breakers giving safe & accurate protection of circuits.

 

We also upgrade main & supplementary equipotential bonding to BS7671 standards.

 

 

Miniature Circuit Breakers

MCBs are mechanical switches that incorporate thermal & magnetic short circuit protection giving accurate & fast disconnection in the case of a fault.

Unlike fuse wires they can be reset without the need of tools.

 

Residual Current Devices

RCDs are earth fault safety trips that monitor the whole installation or individual circuit for earth leakage currents.

In a healthy circuit, phase & neutral currents are balanced. If an earth fault occurs (eg: faulty kettle element) the fault current imbalances the phase & neutral current, which is then detected by the RCD & it quickly isolates the fault.

RCDs protect against fire as fault currents remain low, they are also essential for use with outdoor equipment.

We can advise which type & sensitivity of RCD you require.

 

 

 

BS7671/IEE Wiring Regulations are set out to ensure safe & reliable electrical installations.

 

Fuseboard upgrades are required for various reasons:

Existing earthling devices are obsolete or faulty (eg old fault voltage Earth Leakage Circuit Breakers)

Exisiting Fuse Board is overloaded & requires more outgoing ways for a house extension, etc.

New fuse boxes offer easier resetting of devices in case of a fault. Fuse wire is no longer needed & new devices cannot be fitted with the wrong size of fuse wire.

The installation of RCDs for protection of equipment used outdoors (eg mowers, etc)

The correct size of protective device is essential to disconnect any circuit in case of a fault that could cause a fire or electric shock. Different size cables can carry different size loads, if a cable is overloaded it will get hot.

 

Rewireable fuseboxes are frequently overloaded and should be replaced – for your safety.
