Electricity is an integral part of our daily lives, powering everything from the lights of your homes, to devices we use every day.  But electric systems may be complicated and understanding how they function can be challenging. In this guide we’ll go over the components of an electrical system and describe how circuits function 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 key components that work together to deliver power throughout homes. These include:

Breaker box: the main distribution point for electrical energy in a house, where the electricity is divided into different circuits

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

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

Electrical appliances and devices: the appliances and gadgets that rely on electricity for their functions.

Electrical Circuits

The term "electrical circuit" refers to a pathway that lets electricity flow from the source (the breaker box) to appliances and devices within the home. There are two types of electrical circuits found in the home which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are utilized for most household devices and appliances, whereas the 240-volt circuits are utilized to power larger appliances, such as dryers, air conditioners and electric ones.

Electrical circuits work by creating a loop that allows electricity to be transferred from the source to the device or appliance. The loop consists of a hot cable that transports the power and a neutral wire which completes the circuit, and the ground wire which provides the pathway for electricity to reach the ground in the event the fault occurs.

Understanding Electrical Wiring

Electrical wiring is available in many kinds, such as non-metallic sheathed cables (NM) as well as armored cables (AC) and conduit. Each kind has its own advantages and drawbacks, and the choice of wiring type depends on the specific needs of the installation.

Wiring conducts electricity through a flow of electrons in the wire. Electrons move between the origin and the device or appliance and then back to the source using the neutral wire. It is essential to ensure the wiring is installed and maintained properly, since defective wiring could lead to electrical hazards like shocks and fires.

Common Electrical Issues

Common electrical issues that homeowners face include tripping the light bulbs, flickering breakers and electrical outlets that are not working. These problems can be caused by a myriad of causes that include overloading circuits, loose connections, and faulty wiring.

If you experience any of these issues, it’s crucial to pinpoint the cause and take appropriate action to fix the problem. In certain instances this could mean contacting an accredited electrician to inspect and repair the wiring.
