Electricity is a vital part of our daily lives, supplying everything from the lights of our homes to the devices that we use each day.  But electric systems may be complicated knowing how they work can be challenging. In this article we’ll breakdown the components of an electrical system and explain how circuits work to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

Components of an Electrical System

A home’s electrical system includes a number of important components that work to provide power throughout a home. These include:

Breaker box is the central distribution point for electrical power in homes, where the electricity is divided into different circuits

Outlets and switches: the points at which electricity is supplied to appliances and devices

Wiring: the electrical wires that transmit electric current from the box to the outlets and switches

Electric appliances, devices and equipment: the appliances and gadgets that rely on electricity for their functions.

Electrical Circuits

The term "electrical circuit" refers to a path that allows electricity to flow from the source (the breakers box) to appliances and devices within a home. There are two types of electrical circuits in homes which are 120-volt circuits and circuits with 240-volt voltage. 120-volt circuits are used to power most household appliances and appliances, while the 240-volt circuits are designed to power 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 which transports the power along with a neutral wire that completes the circuit as well as a ground wire that provides a path for electricity to travel to the ground in case there is a problem.

Understanding the electrical Wiring

Electrical wiring is available in a variety of different types, including non-metallic sheathed wire (NM), armored cable (AC), and conduit. Each comes with its own pros and drawbacks and the selection of the type of wiring is based on the particular requirements of the installation.

Electricity travels through wiring through the creation of electrons through the wire. Electrons move from the source to the appliance or device, and back to the source through the neutral wire. It is essential to ensure the wiring is put in place and maintained properly, since improper wiring can cause electrical hazards like shocks and fires.

Common Electrical Problems

The most frequent electrical problems found in homes include tripping breakers, flickering lights, and disconnected outlets. These problems can be caused by a myriad of causes such as overloading circuits poor connections, or faulty wiring.

If you experience any of these issues, it’s essential to identify the root cause and take steps to correct the issue. In some cases this could mean contacting an authorized electrician to look over and fix the wiring.

Concluding and Call to Action
