Electricity is an integral part of our daily lives, powering everything from the lighting in your homes, to appliances that we use each day.  However, electricity systems are complex, and understanding how they work 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.

The components of an electrical system

An electrical system is comprised of several essential components that work to deliver power throughout homes. This includes:

Breaker box is the central distribution point for electrical energy in a house that is where electricity is split into various circuits

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

Wiring: the wires that transmit power from the breaker box, to the outlets and switches

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

Electrical Circuits

A circuit of electricity 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 in homes which are 120-volt circuits and 240-volt circuits. 120-volt circuits are used to power most household appliances and appliances, whereas the 240-volt circuits are utilized to power larger appliances, such as dryers and air conditioners.

Electrical circuits work by completing 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, and the ground wire which 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 kinds, such as non-metallic sheathed cable (NM) and armored cable (AC) and conduit. Each type has its advantages and drawbacks, and the choice of the type of wiring is based on the specific requirements of the installation.

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

Common Electrical Issues

Common electrical issues in homes include tripping breakers, flickering lights, and disconnected outlets. These issues can be caused by a myriad of causes, including overloading circuits, broken connections, and defective wiring.

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

Final Conclusion, and Call to Action
