Electricity is an integral part of our daily life, powering everything from the lighting in our houses to devices that we use each day.  However, electricity systems are complex knowing how they work 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 essential components that work to supply power to a home. These include:

Breaker box: the main distribution point for electrical power in a home that is where electricity is divided into several circuits

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

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

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

Electrical Circuits

A circuit of electricity is one that allows electricity to flow from the main source (the breaker box) to the appliances and devices in a home. There are two types of electrical circuits that can be found in the home that are 120-volt and circuits with 240-volt voltage. 120-volt circuits are used for most household devices and appliances, while the 240-volt circuits are utilized for larger appliances such as dryers, air conditioners and electric ones.

Electrical circuits work by creating the loop which allows electricity to be transferred from the source to the appliance or device. The loop is comprised of a hot wire that transports the power, a neutral wire that completes the circuit and a ground wire , which is an avenue for electricity to travel to the ground in case there is a problem.

Understanding the electrical Wiring

Electrical wiring is available in many different kinds, including non-metallic sheathed cable (NM) and armored cable (AC), and conduit. Each kind has its own advantages and drawbacks, and the choice of the wiring type is contingent upon the particular requirements that the location requires.

Electricity travels through wiring through the creation of electrons in the wire. The electrons travel through the wire from source, to device or appliance returning to the source using the neutral wire. It’s essential to ensure that the wiring is put in place and maintained properly, since defective wiring could lead to electrical hazards like shocks and fires.

Common Electrical Problems

The most frequent electrical problems found at home include tripping light bulbs, flickering breakers and electrical outlets that are not working. These problems can be caused by a myriad of causes such as overloading circuits loose connections, and faulty wiring.

If you’re experiencing any of these issues it is essential to determine the root cause and take action to fix the problem. In some cases it may be necessary to contact an authorized electrician to look over and fix the wiring.
