Old-style fuse boards are still very common in premises across the UK.

An old style fuse board will have a limited number of fuses, allowing for a limited number of circuits. In many cases there will only be four circuits.

At the time this was installed this would have been more than adequate, however electrical usage has increased dramatically with the invention of more electrical machinery and office equipment, printers etc

These circuits may be overloaded in many cases, dangerously so in some.

The 18th edition wiring regulations relating to consumer units

A modern consumer unit will feature as many circuits as necessary and usually has a couple spare for future use.

This will allow the separation of circuits supplying sockets, appliances, immersion heaters, kitchen sockets and outdoor power, plant machinery, servers, office ring mains etc

Each individual circuit will be protected by a miniature circuit breaker “MCB” instead of a fuse, which will feature a switch to disconnect the supply to that circuit.

In line with the IEE 18th edition (BS7671) each circuit should be fitted with an automatic disconnection device, which will isolate the power to that circuit offering significantly improved safety.

Before the consumer unit is changed, the electrician will have checked the distributor’s equipment at the origin of the installation and the earthling and bonding arrangements. This is to ensure that they are safe and that they comply with the regulations.

Test and Inspection in Essex

The nature of this work means that the electrician Essex based SV Electrics sent to carry out the works will have worked on every circuit. He will therefore have to conduct a series of electrical tests on all circuits to ensure that they are safe and will then have to issue an electrical installation certificate before the job is handed over. The tests carried out include

• R1+R2
• Insulation Resistance
• Continuity of Earth Bonding
• Maximum tripping times of the newly installed RCD’s
Any faults found on a circuit will have to be corrected before the circuit is energised.
Checking earthing and bonding
Earthing ensures, in the event of a fault, that the electrical supply would be promptly disconnected to prevent electric shock.

For example, a live wire in a washing machine may have become exposed by a sharp metal edge. This could make the case of the washing machine live resulting in serious injury if touched.

Earthing ensures a fault current flows from the exposed wire to the consumer unit promptly disconnecting the electrical supply and preventing the risk of electric shock.

We always check you’re earthing and bonding with every installation of a commercial or industrial consumer unit, if you are in doubt about the status of your earthing and bonding please call us for advice or a free survey.

Upon completion of all works in line with the latest 18th Edition regulations, then SV Electrics will issue an NICEIC certificate to confirm compliance with the regulations.
