Posted by Local Electrician Northern Beaches on 11 Dec 2025

Electricity is an integral part of our daily life, powering everything from the lights in our homes to the appliances we use every day.  However, electrical systems can be complex, and understanding how they operate can be challenging. In this guide we’ll breakdown the various 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

An electrical system has several key components that work together to supply power to a home. They include:

Breaker box: the main distribution point for electric power in homes, where the electricity is divided into different circuits

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

Wiring: the wires that transport electricity from the breaker box to outlets and switches

Electronic appliances and gadgets: the devices and appliances that use electricity for their functions.

Electrical Circuits

An electrical circuit is one that allows electricity to flow from the point of origin (the breaker box) to the devices and appliances in the home. There are two types of electrical circuits that can be found in homes that are 120-volt and circuits that are 240-volts. 120-volt circuits are utilized for the majority of household appliances and appliances, whereas the 240-volt circuits are utilized to power larger appliances, such as dryers, air conditioners and electric ones.

Electrical circuits function by creating a loop that allows electricity to be transferred from the source to the device or appliance. The loop is made up of a hot cable that carries the electricity along with a neutral wire that completes the circuit and the ground wire which provides an avenue for electricity to travel to the ground in case of a fault.

Understanding the electrical Wiring

Electrical wiring is available in a variety of different types, including non-metallic sheathed cable (NM), armored cable (AC) and conduit. Each has its advantages and drawbacks, and the choice of the wiring type is contingent upon the specific needs of the installation.

Wiring conducts electricity through a flow of electrons in the wire. The electrons travel through the wire from source, to appliance or device returning to the source via the neutral wire. It is essential to ensure the wiring is installed and maintained properly, since faulty wiring can lead to electrical hazards like shocks and fires.

Common Electrical Issues

Some common electrical problems at home include tripping light bulbs, flickering breakers and electrical outlets that are not working. These issues can be caused by a variety of factors that include overloading circuits, poor connections, or faulty wiring.

If you experience one of these problems, it’s essential to identify the cause and take appropriate steps to correct the issue. In certain instances it may be necessary to contact an accredited electrician to examine and fix the wiring.
