Electricity is an essential component of our daily lives, supplying everything from the lights of our homes to the devices we use on a daily basis.  However, electricity systems are complicated and understanding how they function can be difficult. In this article we’ll breakdown 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.

The components of an electrical system

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

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

Switches and outlets: points at which electricity is supplied to devices and appliances

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

Electric appliances, devices and equipment: the appliances and devices that require electricity for their functions.

Electrical Circuits

A circuit of electricity is a path that allows electricity to flow from the main source (the breaker box) to the devices and appliances in the home. There are two kinds of electrical circuits that can be found in the home which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are used to power most household appliances and appliances, whereas the 240-volt circuits are designed to power larger appliances, such as dryers and air conditioners.

Electrical circuits work by creating the loop which allows electricity to flow from the source into the appliance or device. The loop is made up of a hot cable that carries the electricity and a neutral wire which completes the circuit and a ground wire , which is a path for electricity to travel to the ground in the event there is a problem.

Understanding the electrical Wiring

Electrical wiring comes in several kinds, such as non-metallic sheathed cables (NM) and armored cable (AC), and conduit. Each type comes with its own pros and disadvantages and the selection of the wiring type is contingent upon the specific requirements for the particular installation.

Electricity travels through wiring by creating a flow of electrons that travel through the wire. The electrons travel from the source to the appliance or device returning to the source via the neutral wire. It is essential to ensure the wiring is put in place and maintained correctly, as faulty wiring can lead to electrical dangers like shocks and fires.

Common Electrical Problems

The most frequent electrical problems found in homes include tripping breakers, flickering lights and disconnected outlets. These issues 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 is essential to determine the root cause and take actions to rectify the issue. In some cases, this may involve contacting an accredited electrician to examine and fix the wiring.
