What is the difference between a fuse box and an electrical consumer unit?
A fuse box and a consumer unit serve the same purpose. They distribute electricity in your house through multiple circuits and instantly turn the power off whenever a power overload occurs on one of the circuits, which is commonly known as “tripping”. When “tripping” occurs, a consumer unit will switch the power off using the circuit breaker linked to the overloaded circuit. It will turn itself to the position OFF making the faulty circuit easily identifiable. Once the circuit is fixed, the circuit breaker can be switched back on and the power restored. A fuse box uses fuses instead of circuit breakers. Each fuse contains a wire which will melt if there is an electrical overload and make the circuit trip and switch the power off.
It is not as easy to identify a faulty circuit when using a fuse box and the, now melted fuse, will need to be replaced before the power can be restored. Consumer units are basically the modern and safer version of fuse boxes which in most cases are no longer compliant with current electrical regulations. If your house is fitted with an old fuse box, it might be time to for you to replace it.
How much does it cost to replace a fuse box or electrical consumer unit?
The costs of replacing a fuse box or upgrading a consumer unit to a more recent once can vary greatly as it will depend on many factors such as:
Which type of consumer unit is needed
The number of circuits required
