Electricity is a vital part of our everyday life, powering everything from the lighting in our houses to appliances we use on a daily basis.  But electric systems may be complicated, knowing how they function can be difficult. In this guide we’ll breakdown the various components that make up an electric system and explain how circuits work to power appliances and devices.

The components of an electrical system

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

Breaker box: the main source of electrical energy in a house that is where electricity is divided into several circuits

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

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

Electrical appliances and devices: the devices and appliances that use electricity to function

Electrical Circuits

An electrical circuit is a path which allows electricity to flow from the point of origin (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 with 240-volt voltage. 120-volt circuits are utilized for the majority of household appliances and appliances, while the 240-volt circuits are utilized for larger appliances such as air conditioners and electric dryers.

Electrical circuits function by creating the loop which allows electricity to be transferred from the source to the device or appliance. The loop consists of a hot wire which is the conduit for electricity, a neutral wire that completes the circuit, and the ground wire which provides an avenue for electricity to travel to the ground in the event of a fault.

Understanding the electrical Wiring

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

Wiring conducts electricity by creating a flow of electrons that travel through the wire. The electrons travel between the origin and 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 properly, since defective wiring could lead to electrical dangers like shocks and fires.
