Electricity is an essential component of our everyday lives, supplying everything from the lighting in your homes, to devices we use on a daily basis.  However, electricity systems are a bit complicated, making it difficult to understand how they work can be difficult. In this article we’ll go over the elements 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 is comprised of several important components that work to provide power throughout homes. They include:

Breaker box is the central source of electrical energy in a house that is where electricity is split into various circuits

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

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

Electronic appliances and gadgets: the devices and appliances that use electricity for their functions.

Electrical Circuits

An electrical circuit is a path which allows electricity to flow from the main source (the breakers box) to the devices and appliances in the home. There are two types of electrical circuits in the home which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are used for most household devices and appliances, while the 240-volt circuits are utilized to power larger appliances, such as dryers, air conditioners and electric ones.

Electrical circuits work by completing the loop which allows electricity to be transferred from the source to the device or appliance. 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 reach the ground in the event there is a problem.

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 type has its own advantages and drawbacks and the selection of wiring type depends on the particular requirements of the installation.

Wiring conducts electricity by creating a flow of electrons that travel through the wire. The electrons flow between the origin and 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 correctly, as faulty wiring can lead to electrical hazards like shocks and fires.

Common Electrical Issues

Common electrical issues that homeowners face include tripping the breakers, flickering lights and dead outlets. The causes of these issues could be by a variety of factors, including overloading circuits, loose connections, and faulty wiring.

If you are experiencing any of these issues it’s crucial to pinpoint the root cause and take steps to correct the issue. In certain instances, this may involve contacting an authorized electrician to inspect and repair the wiring.
