Posted by East Auckland Electricians on 6 Mar 2025

Electricity is a vital part of our everyday lives, powering everything from the lighting in our houses to gadgets we use every day.  But electrical systems can be a bit complicated, making it difficult to understand how they function can be challenging. In this article we’ll breakdown the various components in an electrical circuit, 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

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

Breaker box is the central distribution point for electrical energy in a house in which the power is split into various circuits

Switches and outlets: points at which electricity is supplied to appliances and devices

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

Electronic appliances and gadgets: the appliances and gadgets that rely on electricity for their functions.

Electrical Circuits

An electrical circuit is one which allows electricity to flow from the source (the breaker box) to appliances and devices within the home. There are two types of electrical circuits in the home: 120-volt circuits and circuits with 240-volt voltage. 120-volt circuits are used for most household devices and appliances, whereas the 240-volt circuits are utilized to power larger appliances, such as dryers, air conditioners and electric ones.

Electrical circuits work by completing an electrical loop that allows power to flow from the source to the appliance or device. The loop is made up of a hot cable that transports the power, a neutral wire that completes the circuit, and a ground wire that provides a path for electricity to reach the ground in case the fault occurs.

Understanding the electrical Wiring

Electrical wiring is available in many different kinds, including non-metallic sheathed wire (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 specific requirements of the installation.

Electricity travels through wiring through a flow of electrons through the wire. The electrons flow between the origin and the appliance or device, and back to the source via the neutral wire. It’s essential to ensure that the wiring is put in place and maintained properly, since faulty wiring can lead to electrical dangers like shocks and fires.

Common Electrical Issues

Common electrical issues in homes include tripping light bulbs, flickering breakers and electrical outlets that are not working. The causes of these issues could be by a variety of factors, including overloading circuits, poor connections, or faulty wiring.

If you are experiencing any of these issues, it is essential to determine the source and take action to fix the problem. In certain instances, this may involve contacting an accredited electrician to inspect and repair the wiring.
