Electricity is an integral part of our lives, powering everything from the lights of our houses to appliances we use every day.  However, electricity systems are complicated, making it difficult to understand how they work can be challenging. In this article we’ll go over the components that make up an electric system, and show how circuits operate to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

Components of an Electrical System

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

Breaker box is the central distribution point for electrical power in a home in which the power is divided into several circuits

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

Wiring: the electrical wires that transport electric current from the box, to the outlets and switches

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

Electrical Circuits

An electrical circuit is one that lets electricity flow from the source (the breaker box) to the appliances and devices in the home. There are two kinds of electrical circuits that can be found in a home which are 120-volt circuits and circuits with 240-volt voltage. 120-volt circuits are used to power most household appliances and appliances, whereas the 240-volt circuits are designed for larger appliances such as dryers and air conditioners.

Electrical circuits function by creating the loop which allows electricity to flow from the source into the device or appliance. The loop is made up of a hot wire which transports the power along with a neutral wire that completes the circuit and a ground wire , which is an avenue for the electricity to get to the ground in the event there is a problem.

Understanding the electrical Wiring

Electrical wiring is available in many different types, including non-metallic sheathed wire (NM) as well as armored cables (AC) and conduit. Each has its advantages and disadvantages, and the choice of wiring type depends on the specific needs for the particular installation.

The electricity travels through wires by creating a flow of electrons in 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 installed and maintained correctly, as defective wiring could lead to electrical hazards such as shocks or fires.

Common Electrical Problems

Common electrical issues at home include tripping breakers, flickering lights, and dead outlets. These issues can be caused due to a variety of reasons such as overloading circuits broken connections, and defective wiring.

If you’re experiencing any of these issues it’s essential to identify the cause and take appropriate steps to correct the issue. In some cases it may be necessary to contact an accredited electrician to inspect and repair the wiring.
