|Does your fuse-board|
look like this?
|To take advantage of modern safety and convenience, it should really look like this!|
We can provide a free quotation to replace existing rewireable fuseboards with Consumer Units containing Minature Circuit Breakers (MCBs) and Residual Current Devices (RCDs). These consumer units have built-in 30mA protection for the use of electrical equipment outdoors and easily re-set circuit breakers giving safe and accurate protection of circuits.
We also upgrade main and supplementary equipotential bonding to BS7671 standards.
Miniature Circuit Breakers
MCBs are mechanical switches that incorporate thermal and magnetic short circuit protection giving accurate and 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 and neutral currents are balanced. If an earth fault occurs (eg: faulty kettle element) the fault current imbalances the phase and neutral current, which is then detected by the RCD and 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 and sensitivity of RCD you require.
Main and supplementary equipotential bonding is required to limit any voltage between simultaneously accessible exposed conductive and extraneous conductive parts.
- An exposed conductive part
- Metal case of electric heater, kettle, toaster, etc.
- An extraneous conductive part
- Taps, shower fittings & metal pipes for gas & water.
Supplementary Equipotential Bonding is required in bath and shower rooms where the risk of an electric shock is high due to moisture and low body resistance.
Bonding comprises of conductors being attached with suitable clamps to water and gas service pipes where they enter the building and to ensure all metallic equipment in rooms of high shock risk (eg bathrooms) is at the same potential.
BS7671/IEE Wiring Regulations are set out to ensure safe and 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 and 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 and 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.

Terms & Conditions
We guarantee to install a new fuseboard in your home including main bonding if required for an all in price of £385.00 . This price includes RCD protection and MCB protection where necessary. The terms that apply to this will include the fusbeboard being for the purpose of a domestic dwelling and not a non-domestic or commercial unit and also with the fuseboard required being no more than a 15 way unit. In addition if a sub-main is required this will not be included nor will the main bonding if it is over a 15 meter run.
