Conduit

Conduit is a protective tube used to enclose and safeguard electrical and communication cables. The type of conduit chosen depends on its application, environmental conditions, and specific wiring requirements. The… Read More »Conduit

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

DC Load

A DC load refers to electrical devices or systems that operate on direct current (DC) rather than alternating current (AC). In Australia, DC loads are commonly found in applications such… Read More »DC Load

Fuse

A fuse is a critical safety device used in electrical circuits to protect against overcurrent, which can cause excessive heat and lead to fires. In Australia, fuses are designed according… Read More »Fuse

Impedance

Electrical impedance is the total opposition that an electrical circuit offers to the flow of alternating current (AC). It combines two factors: resistance and reactance, which together determine how easily… Read More »Impedance

Induction

Induction is the process of generating an electric current or magnetic field without direct contact, usually through the influence of a changing magnetic field. This concept is fundamental in electromagnetism… Read More »Induction

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
