An RCBO is a type of protective device or 'trip switch'. It protects against overload (excessive use of electrical equipment), overcurrent (excessive current from electrical faults) and earth faults. RCBO stands for Residual Current Breaker with Overcurrent.

Electrical overload is a situation where more electrical current is flowing in a circuit than the electrical designer intended. Each electrical circuit is designed and installed to cope with a maximum permanent load and occasional overload. Where continuous overloading occurs, this is beyond the original design constraints of the circuit and needs to be addressed.

In our homes, there is often wiring that is no longer required. This could be for fixed electrical appliances that are no longer in use, have been removed, or where plug sockets have been relocated. UNUSED ELECTRICAL WIRES​ may also come from old electrical components that are outdated or no longer functioning.

When an electric kettle goes faulty, there can be other issues that occur such as a circuit breaker, GFCI or RCD tripping, blow fuses in the panel or fuse box and if there is a fuse in the plug (UK plugs) this can blow also. If the plug is not fused then it is likely that the GFCI or RCD breaker will trip first.

There is a question regarding electrical wiring that comes up very regularly. Can electrical cables be buried? YES, they can. Is it safe to bury electrical cables? Yes, in SOME cases. There are wiring regulations and measures that have to be followed in order to ensure that buried cabling is safe.

What exactly is a CPC when we talk about electrical installations, wiring and systems? CPC stands for Circuit Protective Conductor (sometimes referred to as the EARTH) which is the wire in electrical systems that connects any exposed conductive parts of equipment to the main earthing terminal of the electrical system. What exactly does this mean?

As a fully qualified electrician with years of experience in various electrical projects and installations, I've worked extensively with different types of cables. Today, I want to share my knowledge about 3-core and 2-core cables, explaining what they are, their uses, and how they compare. This information is for anyone involved in electrical work or wanting to understand more about electrics from DIY enthusiasts to professional contractors.

In today's world, electricity is an essential part of our daily lives. From powering our lights and appliances to charging our devices, we rely heavily on our home's electrical system. At the heart of this system lies either a fuse box or a circuit breaker panel, which plays an important role in ensuring our safety and the proper functioning of our electrical devices. But how safe is your fuse box, and should you consider upgrading to circuit breakers? As a fully qualified electrician and electrical lecturer I have seen many old fuse boxes and replaced many of them with a new electrical panel and there are some things that we need to discuss.

As a fully qualified electrician and electrical lecturer with years of experience in the industry, I've seen my fair share of circuit breakers in various states of wear and tear. In this article, I'll share my personal insights on the lifespan of circuit breakers and the factors that can affect their longevity and performance.

A boiler can trip switches in the electrical system for a variety of reasons. Different electrical faults can occur, internal failure of boiler components can short the electrics out and wiring can become damaged due to heat and moisture. We look at 9 common reasons that a boiler would trip the electrical supply.
