Electricity is a vital part of our lives, supplying everything from the lighting in our houses to appliances we use on a daily basis.  However, electrical systems can be complicated making it difficult to understand how they function isn’t easy. In this article we’ll breakdown the various components in an electrical circuit, and explain how circuits work to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

The components of an electrical system

An electrical system has several important components that work to supply power to homes. These include:

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

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

Wiring: the electrical wires that transmit electricity from the breaker box, to the outlets and switches

Electric appliances, devices and equipment: appliances and gadgets that rely on electricity to function.

Electrical Circuits

A circuit of electricity is one that allows electricity to flow from the source (the breakers box) to the appliances and devices in a home. There are two kinds of electrical circuits in the home that are 120-volt and circuits that are 240-volts. 120-volt circuits are utilized to power most household appliances and appliances, while 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 appliance or device. The loop consists of a hot wire that is the conduit for electricity, a neutral wire that completes the circuit, and a ground wire that provides a path for the electricity to get to the ground in the event there is a problem.

Understanding Electrical Wiring

Electrical wiring is available in many different kinds, including non-metallic sheathed cable (NM) and armored cable (AC), and conduit. Each comes with its own pros and disadvantages, and the choice of the type of wiring is based on the particular requirements for the particular installation.

The electricity travels through wires through a flow of electrons that travel through the wire. The electrons travel through the wire from source, to device or appliance returning to the source via the neutral wire. It is essential to ensure the wiring is installed and maintained properly, since faulty wiring can lead to electrical hazards such as shocks or fires.

Common Electrical Issues

Common electrical issues at home include tripping light bulbs, flickering breakers and disconnected outlets. These issues can be caused due to a variety of reasons such as overloading circuits poor connections, or faulty wiring.

If you are experiencing one of these problems, it is essential to determine the source and take action to fix the problem. In some cases it may be necessary to contact an accredited electrician to examine and fix the wiring.
