An electric circuit is a closed loop of wiring that allows electrons to flow from a power source, through components and devices, then back to the source. Think of it as a complete loop where electricity can travel, similar to water flowing through a circular pipe system. Without a complete loop the circuit is broken or "open circuit" and will not function. In this article we will look at various electrical terminology, the construction of a circuit and how this applies in real life situations like our homes.

The question on many of our minds when purchasing or living in an older property is the question of major maintenance. HOW OFTEN SHOULD YOU REWIRE A HOUSE?​ The answer is not as straightforward as you might expect but generally speaking, rewiring may be necessary every 25-30 years possibly longer. There are some exceptions to this and if you are considering purchasing a home, a wiring system that is older than this is not necessarily in need of rewiring. ​ Let me elaborate....

Electrical arcing is a phenomenon that occurs in electrical systems when an electric current flows through an air gap between two conductors. This process can lead to potential hazards, including electrical fires, equipment damage, and severe injuries. Maintaining safe electrical equipment and preventing accidents in both residential and industrial settings is vital to prevent issues like electrical arcing.

As an electrical lecturer, teacher, and electrician, I have spent many years dealing with the installation, maintenance, and troubleshooting of electrical systems. Through both theory and hands-on experience, I have seen first hand the importance of properly functioning electrical infrastructure, particularly in the wake of natural disasters like hurricanes.

​OCPD in electrical terminology stands for Overcurrent Protection Device or Overcurrent Protective Device. The main purpose of an OCPD is to prevent an electrical cable from exceeding the electrical current it can safely carry according to its installation method and any installation factors that have been applied. Where there are branch circuits off a main circuit there is often a supplementary OCPD to protect that particular branch.

When starting or rebranding an electrical business, there are a whole host of things that need to be considered. Perhaps the most important aspect is finding that perfect name for your company to bring in potential customers and to attract your target audience. The right name can create a lasting impression and assist with your brand identity and with so many electrical companies out there, it can be difficult to find catchy electrical company names that are not only a unique name but a memorable name that will lure in potential clients and create a lasting impression in people's minds.

Electrical problems can be worrying so let’s look at WHAT DO TRIPPED CIRCUIT BREAKERS AND BLOWN FUSES INDICATE so you know what to do in an electrical emergency. Blown fuses and tripped circuit breakers are not simply an inconvenience, they indicate that electrical issues are occurring leading to safety hazards with your wiring system. The occasional blown fuse or tripped switch may be as a result of a blown lamp or light bulb but more regular occurrences mean that electrical fires, equipment damage and possibly personal injury are real possibilities. We will take a look at the common causes and reasons for blown fuses and tripped circuit breakers, what they may mean about the condition of the electrical system, its circuits, fuse box and why you should call a licensed electrician to carry out necessary repairs rather than ignoring the situation.

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.
