Voltage is essentially the electrical force that pushes current through a circuit. Current is the flow of electric charge through a circuit, the magnitude of which depends on the voltage pushing and the resistance impeding. Power (Watts) is the rate of electrical energy (Joules) transferred per unit of time (Seconds) in an electrical circuit. Power is calculated by multiplying the Voltage in Volts and the Current in Amps.

​If your microwave keeps tripping the circuit breaker then there is an electrical fault that needs some investigation. It is important to understand that continually resetting a breaker that trips will cause further damage beyond any damage that has already been caused. A microwave oven is an appliance that is generally reliable but occasional electrical problems can result in breaker trips.

An old fuse box should be replaced as soon as possible. If you still have an electrical panel / mains box / fuse box that contains fuses or fuse wire in 2025 then this is likely to be several decades old already and should be replaced.

Are fast track Electrician Courses proper electrical training in 2025? Well in many ways, YES they are. Let me elaborate. In the UK in the past years there was the option to take short courses of as little as three and a half weeks and "qualify". These courses were NOT proper electrical training and missed many key safety benefits of the correct route into the electrical industry.

When testing new installations of electrical systems prior to putting into service, dead tests must be carried out first in order to ensure that any subsequent live testing is safe to carry out.

As a professional electrician, I've often encountered concerns from homeowners about electrical outlets sparking when plugging in devices. While a brief, small spark isn't always a cause for alarm, larger sparks and flashes can indicate a serious problem.

Electrical systems need a way of protecting the wiring from overload and short circuit problems. They achieve this through the use of overcurrent protective devices like fuses and trip switches. In every electrical installation, there should be a main fuse – the final thing to blow in the event of a fault.

Are outdoor sockets safe? Yes, absolutely so long as they are installed according to the National Electrical Code (USA) or the Safety Requirements for Electrical Installations (UK). Any electrical equipment installed outdoors, including outdoor outlets, is perfectly safe so long as the local electrical requirements have been met by the installer. What does this mean? Let’s have a look.

Knowing what uses the most electricity in your home is the first step toward reducing your energy consumption and lowering your electricity bill. As energy costs continue to rise in recent years, homeowners in the United States and the UK are increasingly looking for ways to minimize their electricity usage and carbon footprint, not to mention reducing the cost of energy bills!

Our mobile devices have become something that we rely on constantly. When a phone battery runs low, most of us instinctively reach for the nearest charger without a second thought. But as an electrical lecturer and electrician with many years of industry experience, I've witnessed first-hand the devastating damage that counterfeit chargers and fake phone chargers can cause.
