Electricity is an essential component of our lives, powering everything from the lights in your homes, to appliances we use every day.  But electric systems may be a bit complicated knowing how they function can be challenging. In this article, we’ll break down the various components that make up an electric system and show how circuits operate to power devices and appliances.

The components of an electrical system

An electrical system is comprised of several essential components that work to deliver power throughout the home. These include:

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

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

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

Electric appliances, devices and equipment: devices and appliances that use electricity to function

Electrical Circuits

A circuit of electricity is a pathway which allows electricity to flow from the source (the breakers box) to appliances and devices within a home. There are two kinds of electrical circuits found in homes which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are used for the majority of household appliances and appliances, whereas 240-volt circuits are used to power larger appliances, such as dryers and air conditioners.

Electrical circuits work by completing an electrical loop that allows power to flow from the source into the device or appliance. The loop consists of a hot wire that is the conduit for electricity and a neutral wire which completes the circuit and the ground wire which provides the pathway for the electricity to get to the ground in the event the fault occurs.

Understanding the electrical Wiring

Electrical wiring is available in many different types, including non-metallic sheathed wire (NM) and armored cable (AC), and conduit. Each kind has its own advantages and drawbacks, and the choice of the wiring type is contingent upon the specific requirements that the location requires.

Electricity travels through wiring through a flow of electrons through the wire. Electrons move between the origin and the appliance or device, and back to the source using the neutral wire. It is crucial to make sure that the wiring is put in place and maintained correctly, as faulty wiring can lead to electrical dangers like shocks and fires.

Common Electrical Issues

Some common electrical problems in homes include tripping breakers, flickering lights, and dead outlets. These issues can be caused by a myriad of causes that include overloading circuits, loose connections, and faulty wiring.

If you are experiencing any of these issues, it is essential to determine the root cause and take steps to correct the issue. In some cases this could mean contacting an authorized electrician to inspect and repair the wiring.
