Posted by Local Electrician Bayswater on 16 Apr 2025

Electricity is an integral part of our everyday lives, powering everything from the lights of our houses to devices that we use each day.  However, electrical systems can be a bit complicated, making it difficult to understand how they work isn’t easy. In this article, we’ll break down the components that make up an electric system, and show how circuits operate 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 provide power throughout a home. They include:

Breaker box: the main distribution point for electric energy in a house in which the power is divided into several circuits

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

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

Electric appliances, devices and equipment: the devices and appliances that use electricity for their functions.

Electrical Circuits

An electrical circuit is a pathway which allows electricity to flow from the source (the the breaker box) to the appliances and devices in a home. There are two kinds of electrical circuits found in the home that are 120-volt and circuits with 240-volt voltage. 120-volt circuits are employed to power most household appliances and appliances, while the 240-volt circuits are designed for larger appliances like 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 consists of a hot cable that transports the power and a neutral wire which completes the circuit as well as the ground wire which provides a path for the electricity to get to the ground in case of a fault.

Understanding Electrical Wiring

Electrical wiring comes in several kinds, such as non-metallic sheathed cable (NM) as well as armored cables (AC) and conduit. Each has its own advantages and disadvantages and the selection of the wiring type is contingent upon the particular requirements of the installation.

The electricity travels through wires through a flow of electrons that travel through the wire. The electrons flow through the wire from source, to device or appliance returning to the source through the neutral wire. It is essential to ensure the wiring is put in place and maintained correctly, as improper wiring can cause electrical hazards such as shocks or fires.

Common Electrical Issues

Some common electrical problems in homes include tripping light bulbs, flickering breakers and disconnected outlets. These issues can be caused by a variety of factors such as overloading circuits loose connections, and 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 some instances this could mean contacting a licensed electrician to examine and fix the wiring.
