Electricity is an essential component of our daily life, powering everything from the lights of your homes, to appliances that we use each day.  But electrical systems can be complicated, knowing how they work can be challenging. In this guide we’ll breakdown the elements in an electrical circuit, and explain how circuits work to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

Components of an Electrical System

An electrical system is comprised of several essential components that work to deliver power throughout a home. They include:

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

Outlets and switches: the places where electricity is delivered to devices and appliances

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

Electronic appliances and gadgets: appliances and devices that require electricity to function.

Electrical Circuits

The term "electrical circuit" refers to a path which allows electricity to flow from the point of origin (the the breaker box) to appliances and devices within the home. There are two kinds of electrical circuits that can be found in the home: 120-volt circuits and circuits that are 240-volts. 120-volt circuits are employed for most household devices and appliances, whereas 240-volt circuits are used to power larger appliances, such as dryers and air conditioners.

Electrical circuits work by completing the loop which allows electricity to be transferred from the source to the device or appliance. The loop is made up of a hot wire which carries the electricity and a neutral wire which completes the circuit and a ground wire that provides an avenue for electricity to reach the ground in the event there is a problem.

Understanding the electrical Wiring

Electrical wiring comes in several kinds, such as non-metallic sheathed cable (NM) as well as armored cables (AC) and conduit. Each has its advantages and drawbacks, and the choice of the wiring type is contingent upon the particular requirements of the installation.

The electricity travels through wires through the creation of electrons through the wire. Electrons move between the origin and the device or appliance and then back to the source via the neutral wire. It is essential to ensure the wiring is put in place and maintained properly, since improper wiring can cause electrical hazards such as shocks or fires.

Common Electrical Issues

Some common electrical problems that homeowners face include tripping the light bulbs, flickering breakers and electrical outlets that are not working. The causes of these issues could be by a variety of factors that include overloading circuits, loose connections, and faulty wiring.

If you are experiencing one of these problems, it is essential to determine the cause and take appropriate steps to correct the issue. In certain instances, this may involve contacting a licensed electrician to look over and fix the wiring.
