Electricity is an essential component of our lives, supplying everything from the lights in your homes, to devices we use on a daily basis.  However, electricity systems are complex, making it difficult to understand how they work can be challenging. In this article we’ll go over the elements in an electrical circuit and explain how circuits work to power appliances and devices. Our residential electricians can handle any electrical jobs you need.

The components of an electrical system

An electrical system has several key components that work together to supply power to the home. This includes:

Breaker box: the central source of electrical power in homes, where the electricity is divided into different circuits

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

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

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

Electrical Circuits

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

Electrical circuits work by completing the loop which allows electricity to flow from the source to the device or appliance. The loop is comprised of a hot wire which is the conduit for electricity along with a neutral wire that completes the circuit as well as a ground wire , which is an avenue for the electricity to get to the ground in case there is a problem.

Understanding the electrical Wiring

Electrical wiring is available in a variety of different kinds, including non-metallic sheathed cables (NM) and 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 specific requirements that the location requires.

Wiring conducts electricity through the creation of electrons in the wire. The electrons travel between the origin and the appliance or device and then back to the source via the neutral wire. It is essential to ensure the wiring is put in place and maintained correctly, as faulty wiring can lead to electrical hazards like shocks and fires.

Common Electrical Issues

Some common electrical problems that homeowners face include tripping the breakers, flickering lights and disconnected outlets. These issues can be caused by a myriad of causes that include overloading circuits, loose connections, and faulty wiring.

If you are experiencing any of these issues, it’s crucial to pinpoint the root cause and take action to fix the problem. In certain instances, this may involve contacting an accredited electrician to inspect and repair the wiring.
