Electricity is a vital part of our daily life, powering everything from the lights in your homes, to gadgets we use every day.  However, electricity systems are complex and understanding how they operate isn’t easy. In this guide we’ll go over the components that make up an electric system and show how circuits operate to power appliances and devices.

Components of an Electrical System

An electrical system is comprised of several important components that work to deliver power throughout the home. This includes:

Breaker box: the main distribution point for electric power in a home, where the electricity is divided into different circuits

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

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

Electrical appliances and devices: the appliances and devices that require electricity to function.

Electrical Circuits

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

Electrical circuits function by creating an electrical loop that allows power to be transferred 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 an avenue for electricity to reach the ground in case the fault occurs.

Understanding Electrical Wiring

Electrical wiring is available in a variety of kinds, such as non-metallic sheathed wire (NM) and armored cable (AC), and conduit. Each comes with its own pros and drawbacks, and the choice of the type of wiring is based on the particular requirements of the installation.

The electricity travels through wires through a flow of electrons in the wire. The electrons travel through the wire from source, to device or appliance returning to the source via the neutral wire. It’s essential to ensure that the wiring is put in place and maintained correctly, as faulty wiring can lead to electrical hazards like shocks and fires.

Common Electrical Problems

Common electrical issues in homes include tripping breakers, flickering lights, and electrical outlets that are not working. These issues can be caused by a variety of factors, including overloading circuits, broken connections, and defective wiring.

If you are experiencing any of these issues, it’s essential to identify the source and take actions to rectify the issue. In some cases it may be necessary to contact an accredited electrician to inspect and repair the wiring.
