Fuse Board Upgrades

Old fuse boxes are inevitably accompanied by old wiring.

Neither of which were designed for today’s way of life. Being loaded with an ever-increasing number of appliances, older systems are much less safe than today’s modern installations.

This is what we recommend

If your fuse board or fusebox has a wooden backboard, cast iron or ceramic switches, or a mixture of fuses, it is likely to date back to before the 1960s and should probably be replaced. Older fuse boards and fuseboxes offer little protection from electric shock. 

We would highly recommend upgrading to a metal Consumer Unit (the modern replacement for a Fuse Board) complete with RCD or RCBO protection for your safety along with an SPD to protect the installation.

Why Choose Juice Electrical Services?

Before changing any fuse boards, we will carry out an EICR (Electrical Installation Condition Report). This enables us to check the distributor’s equipment (UK Power Networks*) along with the earthing and bonding arrangements. We do this to make sure everything is connected safely and complies with the current regulations.

We will also carry out all the necessary tests on all circuits. Not only that, but we will also ensure all faults found are resolved before installing a new consumer unit.

RCD and SPD Explained

RCD
RCD stands for Residual Current Device. It is a safety device that switches off electricity automatically if there is a fault. RCDs are far more sensitive than normal fuses and circuit-breakers and offer a level of personal protection that ordinary fuses and circuit-breakers simply cannot provide.

SPD
A Surge Protective Device. It is used to protect the electrical installation, which consists of the consumer unit, wiring and accessories. The protection is against electrical power surges due to the sudden release of energy previously-stored or induced by other means. These can be either naturally occurring such as indirect lightning strikes or man-made.

Indirect lightning strikes most likely happen from a lightning strike on an adjacent overhead power or telephone line. It causes a temporary overvoltage to travel along the lines, which can cause significant damage to the electrical installation and connected equipment.

SPDs are also used to protect your sensitive electronic equipment connected to the installation. Computers, televisions, washing machines and safety circuits, such as fire detection systems and emergency lighting are all protected. Equipment like these with sensitive electronic circuitry can be vulnerable to damage by such events.

Additional Information

Replacing or upgrading a consumer unit in England & Wales is notifiable work under the Building Regulations (Just like having structural work carried out). Once the work has been completed it must be notified to your local council under the Part P Regulations.

As a fully registered NICEIC Approved Contractor Juice Electrical Services can notify your local council on completion of the works on your behalf.

*UK Power Networks – Distribution Network Operator (DNO)
The company that is responsible for the distribution of electricity from the national transmission grid to your home or business is the Distribution Network Operator or DNO. 

Although most people in the UK are familiar with the energy company they buy their electricity from, they actually rely on four types of companies to keep the lights on. These companies make up the UK power network: 

Generation: power plant ownership and operation
Transmission: operate high voltage transmission networks
Distribution: operate local distribution via towers, cables
Suppliers: electricity sellers like SSE, EDF, NPower etc. 

Good to Know:  If you were to experience a power cut call 105. This is free from most landline and mobile numbers and will put you straight through to your District Network Operator.
