Posted by Local Adelaide Electricians on 24 May 2025

Electricity is an integral part of our daily life, powering everything from the lighting in our houses to gadgets we use every day.  But electric systems may be a bit complicated knowing how they work isn’t easy. In this article we’ll breakdown the components that make up an electric system and describe how circuits function to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

Components of an Electrical System

A home’s electrical system includes a number of essential components that work to provide power throughout the home. They include:

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

Outlets and switches: the points where electricity is delivered to appliances and devices

Wiring: the wires that transmit electric current from the box, to the outlets and switches

Electronic appliances and gadgets: the appliances and gadgets that rely on electricity to function

Electrical Circuits

A circuit of electricity is a pathway that lets electricity flow from the point of origin (the breakers box) to appliances and devices within a home. There are two kinds of electrical circuits found in homes: 120-volt circuits and 240-volt circuits. 120-volt circuits are employed for most household devices and appliances, while 240-volt circuits are used to power larger appliances, such as dryers and air conditioners.

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

Understanding the electrical Wiring

Electrical wiring is available in a variety of different types, including non-metallic sheathed cable (NM) and armored cable (AC) and conduit. Each kind comes with its own pros and drawbacks and the selection of the type of wiring is based on the particular requirements that the location requires.

The electricity travels through wires by creating a flow of electrons that travel through the wire. Electrons move from the source to the device or appliance returning to the source through the neutral wire. It’s essential to ensure that the wiring is put in place and maintained correctly, as defective wiring could lead to electrical hazards like shocks and fires.

Common Electrical Issues

Common electrical issues that homeowners face include tripping the breakers, flickering lights and disconnected outlets. These issues can be caused by a variety of factors that include overloading circuits, poor connections, or faulty wiring.

If you’re experiencing any of these issues it’s essential to identify the root cause and take actions to rectify the issue. In certain instances it may be necessary to contact an authorized electrician to look over and fix the wiring.
