Electricity is an integral part of our everyday lives, supplying everything from the lights in our houses to appliances that we use each day.  But electric systems may be complex, making it difficult to understand how they work isn’t easy. In this guide we’ll breakdown the various components that make up an electric system and explain how circuits work to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

Components of an Electrical System

A home’s electrical system includes a number of important components that work to supply power to a home. These include:

Breaker box: the main source of electrical power in a home, where the electricity is divided into several circuits

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

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

Electronic appliances and gadgets: the appliances and devices that require electricity to function.

Electrical Circuits

The term "electrical circuit" refers to a path that allows electricity to flow from the source (the breaker box) to the devices and appliances in the home. There are two types of electrical circuits that can be found in a home: 120-volt circuits and circuits with 240-volt voltage. 120-volt circuits are employed for most household devices and appliances, whereas the 240-volt circuits are designed to power larger appliances, such as dryers, air conditioners and electric ones.

Electrical circuits work by creating an electrical loop that allows power to flow from the source to the appliance or device. The loop is made up of a hot wire that carries the electricity, a neutral wire that completes the circuit as well as a ground wire that provides the pathway for electricity to reach the ground in the event the fault occurs.

Understanding Electrical Wiring

Electrical wiring is available in a variety of different types, including non-metallic sheathed cables (NM) and armored cable (AC) and conduit. Each kind has its advantages and disadvantages and the selection of wiring type depends on the specific requirements that the location requires.

Electricity travels through wiring through a flow of electrons through the wire. The electrons travel from the source to the device or appliance and then back to the source using the neutral wire. It is crucial to make sure that the wiring is put in place and maintained in a correct manner, as defective wiring could lead to electrical dangers like shocks and fires.

Common Electrical Issues

Some common electrical problems at home include tripping breakers, flickering lights and disconnected outlets. The causes of these issues could be by a myriad of causes, including overloading circuits, poor connections, or faulty wiring.

If you are experiencing one of these problems, it’s crucial to pinpoint the root cause and take steps to correct the issue. In some cases it may be necessary to contact a licensed electrician to examine and fix the wiring.
