We can provide a free quotation to replace existing rewireable fuse boards with Consumer Units containing Miniature Circuit Breakers (MCB’s) and Residual Current Devices (RCD’s). 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 MCB’s 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.
Fuse board upgrades are required for various reasons:
- Existing earthling devices are obsolete or faulty (e.g. old fault voltage Earth Leakage Circuit Breakers).
- Existing 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 RCD’s for protection of equipment used outdoors (Fuse board upgrades are required for various reasons:
- Existing earthling devices are obsolete or faulty (e.g. old fault voltage Earth Leakage Circuit Breakers).

- 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 (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.
