Posted by Local Electrician Harrington Park on 14 Nov 2025

Electricity is an integral part of our daily lives, supplying everything from the lights of our houses to appliances that we use each day.  However, electric systems may be a bit complicated, making it difficult to understand how they operate isn’t easy. In this article we’ll breakdown the components in an electrical circuit 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 key components that work together to supply power to a home. They include:

Breaker box: the main source of electrical power in homes, where the electricity is split into various circuits

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

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

Electrical appliances and devices: appliances and devices that require electricity for their functions.

Electrical Circuits

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

Electrical circuits function by creating an electrical loop that allows power to flow from the source to the appliance or device. The loop consists of a hot wire which transports the power along with a neutral wire that completes the circuit, and a ground wire that provides a path for the electricity to get to the ground in the event there is a problem.

Understanding the electrical Wiring

Electrical wiring is available in many different types, including non-metallic sheathed wire (NM) as well as armored cables (AC) and conduit. Each type has its advantages and drawbacks and the selection of wiring type depends on the specific needs of the installation.

Wiring conducts electricity through a flow of electrons in the wire. Electrons move through the wire from source, to appliance or device and then back to the source using the neutral wire. It is crucial to make sure that the wiring is installed and maintained in a correct manner, as defective wiring could lead to electrical dangers like shocks and fires.

Common Electrical Issues

The most frequent electrical problems found that homeowners face include tripping the breakers, flickering lights and electrical outlets that are not working. These problems can be caused due to a variety of reasons such as overloading circuits loose connections, and faulty wiring.

If you are experiencing any of these issues it’s essential to identify the cause and take appropriate steps to correct the issue. In some cases, this may involve contacting a licensed electrician to look over and fix the wiring.

Final Conclusion, and Call to Action

In the end, knowing how electrical wiring works is essential to ensure the safety and security of the electrical system in your home. By adhering to the guidelines laid out in this guide to stay secure and avoid potential dangers.
