Electricity is an integral part of our life, powering everything from the lights in our homes to the devices we use on a daily basis.  But electric systems may be complex knowing how they function isn’t easy. In this guide we’ll go over the various components in an electrical circuit, 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

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

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

Switches and outlets: the places where electricity is delivered 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

A circuit of electricity is a pathway which allows electricity to flow from the point of origin (the breakers box) to appliances and devices within the home. There are two kinds of electrical circuits that can be found in a home which are 120-volt circuits and 240-volt circuits. 120-volt circuits are employed 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 function by creating an electrical loop that allows power to flow from the source into the device or appliance. The loop is made up of a hot cable that carries the electricity, a neutral wire that completes the circuit and a ground wire that provides 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 cable (NM) as well as armored cables (AC), and conduit. Each type comes with its own pros and drawbacks and the selection of wiring type depends on the specific requirements that the location requires.

The electricity travels through wires through 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’s essential to ensure that the wiring is installed and maintained properly, since improper wiring can cause electrical hazards such as shocks or fires.

Common Electrical Problems

Some common electrical problems that homeowners face include tripping the light bulbs, flickering breakers and dead outlets. These issues can be caused by a myriad of causes such as overloading circuits poor connections, or faulty wiring.

If you are experiencing one of these problems, it’s essential to identify the source and take action to fix the problem. In some cases, this may involve contacting an accredited electrician to examine and fix the wiring.
