Electricity is an essential component of our everyday lives, powering everything from the lights of your homes, to appliances we use on a daily basis.  However, electricity systems are complex knowing how they work isn’t easy. In this guide we’ll go over the various components that make up an electric system, 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 important components that work to provide power throughout homes. These include:

Breaker box: the central distribution point for electrical energy in a house that is where electricity is divided into several circuits

Switches and outlets: places where electricity is delivered to devices and appliances

Wiring: the wires that transmit electric current from the box to outlets and switches

Electrical appliances and devices: appliances and gadgets that rely on electricity to function

Electrical Circuits

The term "electrical circuit" refers to one that lets electricity flow from the source (the breaker box) to appliances and devices within a home. There are two kinds of electrical circuits in the home which are 120-volt circuits and 240-volt circuits. 120-volt circuits are utilized for most household devices and appliances, whereas the 240-volt circuits are utilized for larger appliances like air conditioners and electric dryers.

Electrical circuits work by creating 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 and a neutral wire which completes the circuit and the ground wire which provides a path for electricity to travel to the ground in case there is a problem.

Understanding the electrical Wiring

Electrical wiring is available in a variety of kinds, such as non-metallic sheathed wire (NM), armored cable (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.

Wiring conducts electricity by creating a flow of electrons in the wire. The electrons flow between the origin and the device or appliance and then back to the source using the neutral wire. It is essential to ensure the wiring is put in place and maintained in a correct manner, as faulty wiring can lead to electrical dangers like shocks and fires.

Common Electrical Issues

Some common electrical problems that homeowners face include tripping the breakers, flickering lights and disconnected outlets. These issues can be caused by a variety of factors that include overloading circuits, poor connections, or faulty wiring.

If you’re experiencing one of these problems, it is essential to determine the root cause and take actions to rectify the issue. In some cases this could mean contacting an accredited electrician to inspect and repair the wiring.
