Posted by Local Electrician Melbourne on 22 Dec 2025

Electricity is an essential component of our life, powering everything from the lights of your homes, to devices that we use each day.  But electricity systems are a bit complicated, and understanding how they work can be difficult. In this guide we’ll go over the components that make up an electric system, and explain how circuits work to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

The components of an electrical system

An electrical system has several essential components that work to provide power throughout a home. They include:

Breaker box: the central distribution point for electrical power in a home, where the electricity is divided into several circuits

Outlets and switches: the points at which electricity is supplied to devices and appliances

Wiring: the wires that transmit power from the breaker box, to the outlets and switches

Electric appliances, devices and equipment: the appliances and gadgets that rely on electricity to function.

Electrical Circuits

The term "electrical circuit" refers to a path that lets electricity flow from the point of origin (the breakers box) to the devices and appliances in a home. There are two types of electrical circuits found in the home: 120-volt circuits and circuits that are 240-volts. 120-volt circuits are used to power most household appliances and appliances, while the 240-volt circuits are utilized for larger appliances like air conditioners and electric dryers.

Electrical circuits work by completing a loop that allows electricity to flow from the source to the appliance or device. The loop is made up of a hot cable that is the conduit for electricity and a neutral wire which completes the circuit and the ground wire which provides a path for electricity to travel to the ground in the event of a fault.

Understanding Electrical Wiring

Electrical wiring comes in several different kinds, including non-metallic sheathed cables (NM) and armored cable (AC), and conduit. Each type comes with its own pros and disadvantages, and the choice of wiring type depends on the particular requirements of the installation.

Electricity travels through wiring through the creation of electrons in the wire. Electrons move through the wire from source, to appliance or device, and back to the source through the neutral wire. It is crucial to make sure that the wiring is installed and maintained in a correct manner, as faulty wiring can lead to electrical dangers like shocks and fires.

Common Electrical Issues

Common electrical issues at home include tripping breakers, flickering lights, and disconnected outlets. The causes of these issues could be by a variety of factors such as overloading circuits loose connections, and faulty wiring.

If you experience any of these issues, it’s crucial to pinpoint the cause and take appropriate steps to correct the issue. In some cases, this may involve contacting an authorized electrician to inspect and repair the wiring.
