Electricity is an integral part of our everyday lives, supplying everything from the lights of your homes, to devices that we use each day.  However, electricity systems are complex, and understanding how they function can be difficult. In this article, we’ll break down 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 is comprised of several key components that work together to supply power to homes. This includes:

Breaker box: the main distribution point for electrical power in a home that is where electricity is split into various circuits

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

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

Electric appliances, devices and equipment: devices and appliances that use electricity to function

Electrical Circuits

An electrical circuit is a path that allows electricity to flow from the point of origin (the breakers box) to appliances and devices within the home. There are two kinds of electrical circuits found in the home: 120-volt circuits and circuits that are 240-volts. 120-volt circuits are employed for the majority of household appliances and appliances, whereas 240-volt circuits are used for larger appliances like dryers, air conditioners and electric ones.

Electrical circuits work by completing the loop which allows electricity to flow from the source to the appliance or device. The loop is made up of a hot wire which transports the power along with a neutral wire that completes the circuit, and the ground wire which provides the pathway for the electricity to get to the ground in the event of a fault.

Understanding Electrical Wiring

Electrical wiring is available in a variety of different types, including non-metallic sheathed cable (NM), armored cable (AC) and conduit. Each kind comes with its own pros and disadvantages, and the choice of the type of wiring is based on the particular requirements that the location requires.

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 via the neutral wire. It is essential to ensure the wiring is put in place and maintained in a correct manner, as faulty wiring can lead to electrical hazards like shocks and fires.

Common Electrical Problems

Common electrical issues that homeowners face include tripping the breakers, flickering lights, and dead outlets. The causes of these issues could be by a myriad of causes that include overloading circuits, broken connections, and defective wiring.

If you’re experiencing one of these problems, it is essential to determine the root cause and take actions to rectify the issue. In some instances, this may involve contacting an accredited electrician to examine and fix the wiring.
