We can provide a free quotation to replace
existing rewireable fuse boards with Consumer Units containing
Miniature Circuit Breakers (MCB's) & Residual Current Devices (RCD's).
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 MCB's 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.
Fuse board upgrades are required for various reasons:
1. Existing earthling devices are obsolete or faulty (e.g. old
fault voltage Earth Leakage Circuit Breakers)
2. Existing Fuse Board is overloaded & requires more outgoing ways
for a house extension, etc.
3. 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.

4. The installation of RCDs for protection of equipment used
outdoors (e.g. 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.
