Electricity is a vital part of our daily lives, supplying everything from the lighting in your homes, to devices we use every day.  But electrical systems can be complicated and understanding how they function can be difficult. In this guide we’ll breakdown 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.

The components of an electrical system

An electrical system has several essential components that work to supply power to a home. They include:

Breaker box: the main distribution point for electrical energy in a house in which the power 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

Electronic appliances and gadgets: the devices and appliances that use electricity to function.

Electrical Circuits

An electrical circuit is one which allows electricity to flow from the source (the breakers box) to the appliances and devices in a home. There are two kinds of electrical circuits that can be found in a home which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are used for the majority of household appliances 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 an electrical loop that allows power to flow from the source into the device or appliance. The loop is comprised of a hot wire which is the conduit for electricity along with a neutral wire that completes the circuit as well as a ground wire , which is the pathway 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), armored cable (AC) and conduit. Each has its own advantages and drawbacks and the selection of the type of wiring is based on the particular requirements of the installation.

Electricity travels through wiring through a flow of electrons in the wire. The electrons flow from the source to the device or appliance and then back to the source through the neutral wire. It is essential to ensure the wiring is installed and maintained correctly, as improper wiring can cause electrical hazards such as shocks or fires.

Common Electrical Problems

Common electrical issues that homeowners face include tripping the breakers, flickering lights and disconnected outlets. These problems can be caused by a myriad of causes, including overloading circuits, loose connections, and faulty wiring.

If you experience any of these issues, it’s essential to identify the source and take action to fix the problem. In some instances it may be necessary to contact an accredited electrician to inspect and repair the wiring.
