Do you have an old “Fuse box”? Are you are curious about upgrading or worried about the safety of your electrical system? This Fuse box vs Consumer unit guide will help!
In the ever-evolving world of technology and safety standards, the electrical systems in our homes have undergone significant transformations over the years. One of the most noticeable changes is the shift from old-style rewireable fuse boxes to modern consumer units equipped with Residual Current Devices (RCD) and surge protection.
We can use cars as an example. These old rewireable fuse boxes are 40+ years old. Would you still consider an old Ford Cortina as a safe vehicle? Compared to modern vehicles, the chances of injury in a crash are vastly reduced in modern cars. The same applies to electrics. In this blog we'll explore the key differences between these two electrical setups and highlight the advantages that come with embracing the advancements in consumer unit technology.
Rewiring⚡
Manual rewiring. So, a fuse has blown, you need to find the correct rated wire and manually install yourself. There is a degree of technical skill involved and a very real possibility of danger if you replace to fuse with the circuit still under load.
Limited Protection⚠️
Rewireable fuse boxes provided basic protection against overloads and short circuits but lacked the advanced features found in modern consumer units.
Combustible Materials🔥
Old rewireable fuse boxes are made of plastic and wood. In the unfortunate event of an electrical fire, the enclosure is likely to allow the fire to spread. Modern consumer units are metal and will reduce this issue greatly.
Modern Consumer Units with RCD Protection
Circuit Breakers
Consumer units use circuit breakers instead of traditional fuses. These circuit breakers can be reset with a simple switch, eliminating the need for manual replacement.
Residual Current Devices (RCD/RCBO)
One of the most significant advancements is the integration of RCDs, which constantly monitor the flow of electricity and automatically cut off the power if they detect a fault.
RCDs provide enhanced protection against electric shocks and significantly reduce the risk of fatal accidents, especially in wet or damp environments.
Selective Tripping
Modern consumer units often feature selective tripping, allowing only the affected circuit to be disconnected in case of a fault, minimizing disruptions to the entire electrical system.
Surge Protection
In an era where electronic devices are ubiquitous, the threat of power surges is ever-present. Old fuse boxes offer minimal defence against sudden voltage spikes that can damage sensitive electronics. Modern consumer units are equipped with surge protection features, shielding your valuable appliances and devices from the harmful
effects of electrical surges. This not only ensures the longevity of your electronics but also saves you from the inconvenience and cost of replacing damaged equipment.
Improved Safety Standards
The implementation of RCD protection aligns with modern safety standards, making homes safer and reducing the risk of electrical accidents.
Ease of Maintenance
Circuit breakers in consumer units are easily reset, simplifying the maintenance process. Homeowners can restore power with a flip of a switch, without the need for specialized knowledge.
The transition from old rewireable fuse boxes to modern consumer units with RCD protection represents a significant leap in electrical safety. The incorporation of advanced technologies not only enhances protection against electrical faults but also simplifies maintenance for homeowners. As we continue to prioritize safety in our homes, embracing these technological advancements becomes essential for a secure and efficient electrical system. Upgrading to a modern consumer unit is a smart investment in safeguarding your home and loved ones from potential electrical hazards.
