Contactor
A contactor is an electrically controlled switching device used to control the flow of electricity in a power circuit. It functions much like a relay but is designed specifically for… Read More »Contactor
Short Circuit
A short circuit is an electrical fault that occurs when electricity takes an unintended path with little or no resistance. Instead of flowing through the intended circuit—such as a light,… Read More »Short Circuit
Power Factor
Power factor is a measure of how effectively electrical power is being used in a system. It is a ratio, expressed as a number between 0 and 1 (or as… Read More »Power Factor
Insulators
Electrical insulators are materials that resist the flow of electric current. They do not allow electrons to move freely through them, making them essential for safely managing electricity in various… Read More »Insulators
Safety Switches (RCDs)
Safety switches, also known as Residual Current Devices (RCDs), are critical safety devices designed to protect individuals from electric shock and prevent electrical fires. In Australia, including Port Macquarie, NSW,… Read More »Safety Switches (RCDs)
Circuit Breaker
A circuit breaker is a critical safety device used in electrical systems to protect circuits from overloads and short circuits. In Australia, including New South Wales (NSW), circuit breakers are… Read More »Circuit Breaker
Surge Protector
A surge protector is an electrical device designed to protect electrical equipment from voltage spikes and surges, which can be caused by lightning strikes, power outages, or other disruptions in… Read More »Surge Protector
Three-Phase Load
A three-phase load refers to an electrical system that uses three separate alternating currents (AC) phases to distribute power. This type of power distribution is commonly used in commercial and… Read More »Three-Phase Load
Fused Spurs
A fused spur, also known as a fused connection unit (FCU), is an electrical device used to provide a safe and convenient method of connecting and isolating electrical appliances in… Read More »Fused Spurs
