Posted by Residential Electrician Adelaide on 18 Nov 2025

Electricity is an integral part of our lives, supplying everything from the lights of our houses to devices we use on a daily basis.  But electric systems may be a bit complicated knowing how they work can be challenging. In this guide, we’ll break down the various components of an electrical system, and explain how circuits work to power appliances and devices. Our residential electricians can handle any electrical jobs you need.

Components of an Electrical System

An electrical system is comprised of several key components that work together to deliver power throughout homes. These include:

Breaker box is the central distribution point for electric energy in a house that is where electricity is divided into several circuits

Switches and outlets: places where electricity is delivered to devices and appliances

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

Electrical appliances and devices: appliances and devices that require electricity to function

Electrical Circuits

The term "electrical circuit" refers to a path which allows electricity to flow from the main source (the breaker box) to the appliances and devices in the home. There are two kinds of electrical circuits that can be found in a home: 120-volt circuits and circuits that are 240-volts. 120-volt circuits are employed for most household devices and appliances, while the 240-volt circuits are utilized for larger appliances such as dryers, air conditioners and electric ones.

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

Understanding Electrical Wiring

Electrical wiring is available in a variety of different kinds, including non-metallic sheathed cable (NM), armored cable (AC) and conduit. Each has its own advantages and drawbacks and the selection of the type of wiring is based on the specific needs that the location requires.

Wiring conducts electricity through the creation of electrons that travel through the wire. The electrons travel between the origin and the appliance or device, and back to the source using the neutral wire. It is crucial to make sure that the wiring is put in place and maintained properly, since improper wiring can cause electrical hazards like shocks and fires.

Common Electrical Problems

The most frequent electrical problems found in homes include tripping breakers, flickering lights and disconnected outlets. These problems can be caused by a myriad of causes such as overloading circuits poor connections, or faulty wiring.

If you experience one of these problems, it’s crucial to pinpoint the root cause and take actions to rectify the issue. In some cases, this may involve contacting an authorized electrician to examine and fix the wiring.
