Electricity is a vital part of our everyday lives, powering everything from the lighting in our houses to gadgets that we use each day.  However, electrical systems can be a bit complicated knowing how they operate can be difficult. In this article we’ll breakdown the various 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 essential components that work to provide power throughout homes. This includes:

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

Switches and outlets: the points where electricity is delivered to devices and appliances

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

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

Electrical Circuits

An electrical circuit is one which allows electricity to flow from the source (the the breaker box) to the devices and appliances in the home. There are two kinds of electrical circuits that can be found in a home: 120-volt circuits and 240-volt circuits. 120-volt circuits are used for most household devices and appliances, while the 240-volt circuits are utilized to power larger appliances, such as dryers and air conditioners.

Electrical circuits work by creating the loop which allows electricity to be transferred from the source to the appliance or device. The loop is comprised of a hot cable that carries the electricity, a neutral wire that completes the circuit as well as the ground wire which provides the pathway for electricity to reach the ground in case the fault occurs.

Understanding the electrical Wiring

Electrical wiring is available in a variety of different kinds, including non-metallic sheathed wire (NM) as well as armored cables (AC), and conduit. Each kind comes with its own pros and drawbacks and the selection of the type of wiring is based on the specific requirements of the installation.

Wiring conducts electricity by creating a flow of electrons in the wire. The electrons flow through the wire from source, to appliance or device returning to the source via the neutral wire. It’s essential to ensure that the wiring is put in place and maintained properly, since defective wiring could lead to electrical dangers like shocks and fires.

Common Electrical Problems

The most frequent electrical problems found at home include tripping breakers, flickering lights, and disconnected outlets. These problems can be caused due to a variety of reasons, including overloading circuits, poor connections, or faulty wiring.

If you’re experiencing any of these issues, it’s essential to identify the root cause and take steps to correct the issue. In some cases this could mean contacting an authorized electrician to examine and fix the wiring.

Concluding and Call to Action

In the end, knowing how electrical wiring works is crucial for ensuring the security and reliability of your home’s electrical system. By following the guidelines outlined in this document to stay secure and stay clear of potential dangers.
