Electricity is an essential component of our life, powering everything from the lights of our houses to gadgets that we use each day.  But electrical systems can be complicated making it difficult to understand how they work can be difficult. In this article we’ll breakdown the elements that make up an electric system, and show how circuits operate to power devices and appliances.

Components of an Electrical System

An electrical system is comprised of several important components that work to provide power throughout the home. This includes:

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

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

Wiring: the wires that carry electric current from the box to the outlets and switches

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

Electrical Circuits

The term "electrical circuit" refers to a pathway that lets electricity flow from the point of origin (the breakers box) to appliances and devices within the home. There are two types of electrical circuits found in homes: 120-volt circuits and circuits with 240-volt voltage. 120-volt circuits are utilized for most household devices and appliances, while 240-volt circuits are used for larger appliances like air conditioners and electric dryers.

Electrical circuits work by creating an electrical loop that allows power to be transferred from the source to the device or appliance. The loop is comprised of a hot wire that transports the power along with a neutral wire that completes the circuit as well as a ground wire that provides an avenue for the electricity to get to the ground in case the fault occurs.

Understanding the electrical Wiring

Electrical wiring is available in a variety of different kinds, including non-metallic sheathed cable (NM), armored cable (AC) and conduit. Each type comes with its own pros and drawbacks and the selection of the type of wiring is based on the specific needs for the particular installation.

Electricity travels through wiring by creating a flow of electrons through the wire. The electrons flow from the source to the device or appliance and then back to the source through the neutral wire. It is essential to ensure the wiring is put in place and maintained correctly, as faulty wiring can lead to electrical dangers like shocks and fires.

Common Electrical Problems

Some common electrical problems in homes include tripping breakers, flickering lights and dead outlets. The causes of these issues could be due to a variety of reasons such as overloading circuits poor connections, or faulty wiring.

If you experience one of these problems, it’s essential to identify the root cause and take steps to correct the issue. In some cases it may be necessary to contact an accredited electrician to examine and fix the wiring.
