Electricity is an essential component of our daily life, powering everything from the lights in our houses to devices we use every day.  However, electric systems may be a bit complicated and understanding how they function isn’t easy. In this guide, we’ll break down the elements that make up an electric system, 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 essential components that work to supply power to a home. These include:

Breaker box is the central distribution point for electrical energy in a house in which the power is divided into different circuits

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

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

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

Electrical Circuits

The term "electrical circuit" refers to one which allows electricity to flow from the point of origin (the breaker box) to appliances and devices within a home. There are two types of electrical circuits found in homes 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 designed for larger appliances such as air conditioners and electric dryers.

Electrical circuits function 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 and a neutral wire which completes the circuit as well as a ground wire that provides an avenue for electricity to reach the ground in the event of a fault.

Understanding Electrical Wiring

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

Wiring conducts electricity through the creation of electrons that travel through the wire. The electrons travel through the wire from source, to device or appliance returning to the source through the neutral wire. It is crucial to make sure that the wiring is put in place and maintained correctly, as improper wiring can cause electrical dangers like shocks and fires.

Common Electrical Issues

Some common electrical problems that homeowners face include tripping the breakers, flickering lights, and electrical outlets that are not working. These issues can be caused due to a variety of reasons such as overloading circuits loose connections, and faulty wiring.

If you experience any of these issues it’s crucial to pinpoint the root cause and take actions to rectify the issue. In some cases this could mean contacting an accredited electrician to inspect and repair the wiring.
