Electricity is an integral part of our everyday life, powering everything from the lights of your homes, to appliances that we use each day.  But electric systems may be a bit complicated, making it difficult to understand how they operate can be difficult. In this article, we’ll break down the components in an electrical circuit, and describe how circuits function to power appliances and devices. 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 deliver power throughout the home. These include:

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

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

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

Electronic appliances and gadgets: the appliances and gadgets that rely on electricity for their functions.

Electrical Circuits

A circuit of electricity is one that allows electricity to flow from the source (the breaker box) to the appliances and devices in the home. There are two types of electrical circuits in a home: 120-volt circuits and 240-volt circuits. 120-volt circuits are used for the majority of household appliances and appliances, while the 240-volt circuits are designed 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 is made up of a hot wire that carries the electricity along with a neutral wire that completes the circuit and the ground wire which provides the pathway for electricity to travel to the ground in the event of a fault.

Understanding Electrical Wiring

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

Wiring conducts electricity through a flow of electrons through the wire. The electrons travel through the wire from source, to device or appliance and then back to the source using the neutral wire. It’s essential to ensure that the wiring is installed and maintained properly, since faulty wiring can lead to electrical dangers like shocks and fires.

Common Electrical Issues

The most frequent electrical problems found in homes include tripping light bulbs, flickering breakers and disconnected outlets. These issues can be caused by a variety of factors that include overloading circuits, broken connections, and defective wiring.

If you’re experiencing any of these issues, it’s essential to identify the source and take steps to correct the issue. In certain instances it may be necessary to contact an accredited electrician to examine and fix the wiring.
