Why You Need to Get Rid of Those Ceramic Fuses As Soon As Possible


If you've just taken possession of a house that may have been in your family for generations, it may be badly in need of an upgrade. It might have been occupied by an elderly relative for decades, but little work has been done to bring it up to date during this time. In this case, you need to focus on safety first and start with the electrical installation. In particular, you will need to act without any delay if you find some ceramic fuses in your switchboard, but why the urgency?

Original Spec

Many years ago, a home like this would have been protected by rudimentary ceramic fuses. These were essentially based on fuse wire that was looped around a pair of screws and that would provide a 'sensitive' connection when the power was switched on. If there was an overload somewhere, then the fuse wire would be the first to give, and it would break in order to shut off the circuit. However, there was no guarantee that they would work in every situation and, therefore, there was a risk that an individual could receive an electric shock from a dodgy appliance. Furthermore, there was no guarantee that these rewireable fuses would contain any significant overload, and this would increase the risk of fire throughout the property.

Improvements

Times have moved on since those ceramic fuses were de rigueur. They would have been replaced by circuit breakers that were self-contained and that would plug into the base, but they would still only offer limited protection. It took some time until circuit breakers were hardwired into the board and still more time until the more efficient RCD switches arrived. These residual current devices offered far more protection, and they would instantaneously trip at the first sign of a problem. Consequently, the risk of electric shock would be considerably reduced, but the early devices would cut off power to the entire property.

Modern Solution

Today, you need protection from combination breakers and switches known as RCBOs. These are highly specific and will isolate a single circuit should a problem arise. Further, they use technology that can identify nonhazardous issues and will only operate when the threat is real.

Taking Action

Bring in a qualified electrician as soon as you can for switchboard upgrades. Once they have installed the latest technology, they will give you a certificate to prove compliance with current standards.
