Components of an Electrical System

An electrical system has several key components that work together to deliver power throughout homes. They include:

Breaker box is the central source of electrical energy in a house, where the electricity is divided into different circuits

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

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

Electric appliances, devices and equipment: the devices and appliances that use electricity for their functions.

Electrical Circuits

The term "electrical circuit" refers to a path which allows electricity to flow from the source (the breakers box) to appliances and devices within a home. There are two types of electrical circuits that can be found in homes which are 120-volt circuits and circuits with 240-volt voltage. 120-volt circuits are used to power most household appliances and appliances, whereas 240-volt circuits are used for larger appliances like air conditioners and electric dryers.

Electrical circuits work by creating a loop that allows electricity to be transferred 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, and the ground wire which provides the pathway for the electricity to get to the ground in case there is a problem.

Understanding Electrical Wiring

Electrical wiring is available in many different types, including non-metallic sheathed cables (NM) and armored cable (AC) and conduit. Each type has its advantages and disadvantages and the selection of the type of wiring is based on the specific needs of the installation.

The electricity travels through wires through a flow of electrons through the wire. The electrons travel through the wire from source, to appliance or device and then back to the source using 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.
