Electricity is a vital part of our lives, supplying everything from the lighting in our homes to the gadgets we use every day.  However, electrical systems can be complicated, and understanding how they function can be challenging. In this guide we’ll breakdown the various components in an electrical circuit and describe how circuits function to power appliances and devices. Our residential electricians can handle any electrical jobs you need.

Components of an Electrical System

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

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

Switches and outlets: places where electricity is delivered to appliances and devices

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

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

Electrical Circuits

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

Electrical circuits work by creating the loop which allows electricity to be transferred from the source to the appliance or device. The loop is comprised of a hot wire that is the conduit for electricity along with a neutral wire that completes the circuit, and a ground wire that provides an avenue for electricity to travel to the ground in case there is a problem.

Understanding Electrical Wiring

Electrical wiring comes in several different types, including non-metallic sheathed cable (NM), armored cable (AC), and conduit. Each kind comes with its own pros and drawbacks and the selection of the wiring type is contingent upon the specific requirements that the location requires.

Electricity travels through wiring through the creation of electrons through the wire. The electrons flow through the wire from source, to appliance or device and then back to the source via the neutral wire. It’s essential to ensure that the wiring is put in place and maintained correctly, as defective wiring could lead to electrical hazards such as shocks or fires.

Common Electrical Problems

Some common electrical problems in homes include tripping breakers, flickering lights, and disconnected outlets. These problems can be caused by a myriad of causes that include overloading circuits, poor connections, or faulty wiring.

If you are experiencing any of these issues it’s crucial to pinpoint the cause and take appropriate actions to rectify the issue. In certain instances this could mean contacting a licensed electrician to examine and fix the wiring.
