Electricity is a vital part of our daily lives, supplying everything from the lights in our homes to the appliances we use on a daily basis.  But electricity systems are complicated, and understanding how they work can be difficult. In this guide we’ll go over the various components of an electrical system and explain how circuits work to power devices and appliances.

The components of an electrical system

An electrical system has several important components that work to deliver power throughout a home. These include:

Breaker box: the main distribution point for electric energy in a house in which the power is divided into different circuits

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

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

Electric appliances, devices and equipment: the appliances and devices that require electricity to function

Electrical Circuits

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

Electrical circuits work by completing the loop which allows electricity to be transferred from the source to the appliance or device. The loop is made up of a hot wire which 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 the event the fault occurs.

Understanding the electrical Wiring

Electrical wiring is available in a variety of kinds, such as non-metallic sheathed cable (NM) as well as armored cables (AC) and conduit. Each comes with its own pros and disadvantages and the selection of the type of wiring is based on the particular requirements that the location requires.

Electricity travels through wiring by creating a flow of electrons that travel through the wire. The electrons travel between the origin and the appliance or device, and back to the source using the neutral wire. It’s essential to ensure that the wiring is put in place and maintained correctly, as improper wiring can cause electrical hazards like shocks and fires.

Common Electrical Problems

The most frequent electrical problems found that homeowners face include tripping the breakers, flickering lights, and dead outlets. These problems can be caused by a myriad of causes such as overloading circuits broken connections, and defective wiring.

If you are experiencing one of these problems, it’s crucial to pinpoint the source and take steps to correct the issue. In some cases this could mean contacting a licensed electrician to look over and fix the wiring.
