Electricity is a vital part of our everyday lives, supplying everything from the lighting in your homes, to appliances we use on a daily basis.  However, electrical systems can be complex knowing how they operate can be difficult. In this article, we’ll break down the 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.

The components of an electrical system

A home’s electrical system includes a number of key components that work together to provide power throughout homes. These include:

Breaker box: the main source of electrical power in homes in which the power is divided into different circuits

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

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

Electronic appliances and gadgets: the appliances and gadgets that rely on electricity to function

Electrical Circuits

The term "electrical circuit" refers to a path which allows electricity to flow from the main source (the the breaker box) to the appliances and devices in the home. There are two types of electrical circuits in homes: 120-volt circuits and circuits that are 240-volts. 120-volt circuits are used for most household devices and appliances, while the 240-volt circuits are utilized to power larger appliances, such as dryers, air conditioners and electric ones.

Electrical circuits work by completing the loop which allows electricity to flow from the source into the appliance or device. The loop is comprised of a hot wire that transports the power and a neutral wire which completes the circuit as well as a ground wire that provides an avenue for electricity to reach the ground in the event the fault occurs.

Understanding the electrical Wiring

Electrical wiring is available in a variety of kinds, such as non-metallic sheathed wire (NM) as well as armored cables (AC) and conduit. Each type has its advantages and disadvantages, and the choice of the type of wiring is based on the specific requirements that the location requires.

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

Common Electrical Issues

Common electrical issues in homes include tripping breakers, flickering lights and dead outlets. The causes of these issues could be by a variety of factors such as overloading circuits loose connections, and faulty wiring.

If you’re experiencing one of these problems, it is essential to determine the cause and take appropriate action to fix the problem. In some instances this could mean contacting a licensed electrician to inspect and repair the wiring.
