Electricity is an integral part of our daily life, powering everything from the lights in our houses to devices that we use each day.  But electrical systems can be a bit complicated, making it difficult to understand how they function can be difficult. In this article we’ll go over the various components that make up an electric system, and show how circuits operate to power devices and appliances.

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 that is where electricity is divided into several circuits

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

Wiring: the wires that carry electricity from the breaker box to outlets and switches

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

Electrical Circuits

An electrical circuit is one which allows electricity to flow from the main source (the the breaker box) to the devices and appliances in a home. There are two types of electrical circuits that can be found in the home which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are utilized for the majority of household appliances and appliances, whereas the 240-volt circuits are utilized for larger appliances like dryers and air conditioners.

Electrical circuits work by creating the loop which allows electricity to flow from the source to the appliance or device. The loop consists of a hot wire that is the conduit for electricity, a neutral wire that completes the circuit as well as 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 many different types, including non-metallic sheathed cables (NM) as well as armored cables (AC), and conduit. Each type comes with its own pros and drawbacks, and the choice of wiring type depends on the particular requirements 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 device or appliance, and back to the source through the neutral wire. It is crucial to make sure that the wiring is put in place and maintained in a correct manner, as defective wiring could lead to electrical hazards such as shocks or fires.

Common Electrical Problems

The most frequent electrical problems found that homeowners face include tripping the breakers, flickering lights and dead outlets. The causes of these issues could be by a variety of factors such as overloading circuits broken connections, and defective wiring.

If you’re experiencing one of these problems, it is essential to determine the source and take actions to rectify the issue. In certain instances it may be necessary to contact a licensed electrician to inspect and repair the wiring.
