Welcome to Full Circuit Solutions - Your Local Expert Electricians.  

As a homeowner you may be considering electrical installation works to enhance your living space. However, before proceeding with any upgrades, it is crucial to address the state of your existing fuse box. In this article, we'll explore four compelling reasons why upgrading your outdated and non-compliant fuse box to a modern consumer unit with RCD and SPD protection is imperative before any electrical installation works take place.

Enhanced Safety for You & Your Family👪

We have often encountered cases where DIY enthusiasts or unqualified individuals install new equipment on old fuse boxes, leading to significant safety hazards. The older wooden-backed rewirable fuseboards, such as the 3036 board, were designed for a much lower electrical demand. Nowadays, with the prevalence of electric devices, the household's electrical demand has surged. If your fuse box isn't upgraded to accommodate this additional load, there is an increased risk of your fusebox overloading, posing fire risks and endangering your home and family's safety.

Compliance with BS7671 Regulations & RCD Protection✔️

Newer consumer units offer RCD (Residual Current Device) protection, which has become the standard for electrical safety within households. Without RCD protection, no new accessories can be safely installed. An RCD is a safety device that detects even the smallest imbalance between the line and neutral conductors. When correctly installed, it will cause a circuit to trip within 40 milliseconds upon detecting a fault, preventing potential electrocution and other serious accidents.

Inadequate Space for Additional Protective Devices⚠️

Outdated fuse boxes may lack sufficient space to accommodate additional protective devices. We often encounter circuits "doubled up" in a single circuit breaker due to this limitation. This practice not only compromises the efficiency of protective devices but also leads to poor terminations and overloading, increasing the risk of fire and electrical failures.

Ensuring Future Maintenance and Spare Parts Availability

If your existing fuse box or consumer unit is obsolete, obtaining spare parts for proper maintenance becomes increasingly challenging. Upgrading to a modern consumer unit ensures that you can readily access spare parts when needed, allowing for effective and timely maintenance, thus ensuring the long-term safety and reliability of your electrical system.



At Full Circuit Solutions, we've witnessed the consequences of outdated fuse boxes and unqualified installations, and we strongly emphasize the necessity of upgrading your fuse box to a modern consumer unit before any electrical installation works.
