Electricity is an essential component of our everyday lives, powering everything from the lights in our houses to appliances we use on a daily basis.  However, electricity systems are complex knowing how they operate can be challenging. In this article we’ll breakdown the elements that make up an electric system, and explain how circuits work to power appliances and devices.

Components of an Electrical System

An electrical system has several essential components that work to supply power to a home. They include:

Breaker box is the central distribution point for electric energy in a house, where the electricity is divided into several circuits

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

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

Electric appliances, devices and equipment: the appliances and devices that require electricity to function.

Electrical Circuits

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

Electrical circuits work by completing the loop which allows electricity to flow from the source to the appliance or device. The loop is comprised of a hot wire that is the conduit for electricity, a neutral wire that completes the circuit, and a ground wire that provides an avenue for electricity to travel to the ground in case there is a problem.

Understanding Electrical Wiring

Electrical wiring is available in a variety of different kinds, including non-metallic sheathed cable (NM) as well as armored cables (AC) and conduit. Each comes with its own pros and drawbacks and the selection of the wiring type is contingent upon the particular requirements that the location requires.

Wiring conducts electricity through the creation of electrons in the wire. The electrons flow from the source to the appliance or device and then back to the source using the neutral wire. It is crucial to make sure that the wiring is put in place and maintained properly, since improper wiring can cause electrical dangers like shocks and fires.

Common Electrical Problems

Common electrical issues at home include tripping breakers, flickering lights and disconnected outlets. The causes of these issues could be by a variety of factors, including overloading circuits, broken connections, and defective wiring.

If you are experiencing one of these problems, it’s essential to identify the cause and take appropriate action to fix the problem. In some instances this could mean contacting an authorized electrician to inspect and repair the wiring.
