Rewiring

image of electrical wires East Kent Electrical can offer full rewires or just partial rewires. We will design the circuits to comply with building regulations. All circuits will be fully protected, and tested. Certification is automatically given. Any new installation is notified to building control under the part P scheme; A 6 Year warrantee is given and backed by the NICEIC. Our electricians have many years experience in rewiring existing properties. We offer free quotations for work ranging from a full rewire to a selection of small alterations & repairs.

We will be happy to discuss your requirements & advise on the work requested.

All domestic installation work (with some minor exceptions) has to be tested & inspected & the client issued with suitable certification. The work also has to be registered with the Local Building Control Body through the Domestic Installer Scheme.

Part & Full Rewires

Electrical rewiring involves the replacement of old, dangerous or non-compliant electrical equipment, eg; cables, fittings, distribution boards, etc.

This work can vary from a full rewire replacing all cables, fittings, distribution equipment, etc with the cables chased into the walls & completely hidden to a surface rewire where the cables are hidden in mini trunking fitted onto the surface of the walls.

A part rewire may be the replacement of a section of the installation or just the updating of the fuseboxes, fittings or cables to upgrade an installation to the current regulations.

Fuse Board Upgrades

We 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.

Bonding Main/Supplementary

Main & supplementary equipotential bonding is required to limit any voltage between simultaneously accessible exposed conductive & 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 & shower rooms where the risk of an electric shock is high due to moisture & low body resistance.

Bonding comprises of conductors being attached with suitable clamps to water & gas service pipes where they enter the building & 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 & 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)
Existing 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.
