Electricity is an integral part of our everyday lives, supplying everything from the lighting in your homes, to devices that we use each day.  But electricity systems are complicated knowing how they function isn’t easy. In this guide, we’ll break down the components in an electrical circuit 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 is comprised of several important components that work to supply power to a home. They include:

Breaker box is the central source of electrical power in homes, where the electricity is divided into several circuits

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

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

Electronic appliances and gadgets: the devices and appliances that use electricity to function.

Electrical Circuits

The term "electrical circuit" refers to a path which allows electricity to flow from the source (the breakers box) to the devices and appliances in the home. There are two types of electrical circuits in the home which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are utilized to power most household appliances and appliances, whereas the 240-volt circuits are utilized for larger appliances such as air conditioners and electric dryers.

Electrical circuits work by creating the loop which allows electricity to be transferred from the source to the appliance or device. The loop is made up of a hot wire that transports the power along with a neutral wire that completes the circuit, and the ground wire which provides an avenue for electricity to reach the ground in the event the fault occurs.

Understanding Electrical Wiring

Electrical wiring comes in several different types, including non-metallic sheathed wire (NM) as well as armored cables (AC) and conduit. Each comes with its own pros and drawbacks, and the choice of wiring type depends on the particular requirements for the particular installation.

Wiring conducts electricity by creating a flow of electrons in the wire. Electrons move through the wire from source, to appliance or device, and back to the source via the neutral wire. It’s essential to ensure that the wiring is installed and maintained correctly, as defective wiring could lead to electrical hazards like shocks and fires.

Common Electrical Issues

The most frequent electrical problems found that homeowners face include tripping the light bulbs, flickering breakers and disconnected outlets. These issues can be caused by a myriad of causes, including overloading circuits, broken connections, and defective wiring.

If you experience any of these issues it’s essential to identify the cause and take appropriate actions to rectify the issue. In some cases it may be necessary to contact an accredited electrician to look over and fix the wiring.

Conclusion and Call to Action

In the end, knowing how electrical wiring works is vital to ensure the safety and reliability of the electrical system in your home. By following the guidelines outlined in this article, you can stay secure and avoid potential dangers.
