Electricity is a vital part of our life, powering everything from the lighting in our homes to the gadgets we use every day.  However, electrical systems can be complicated making it difficult to understand how they operate can be challenging. In this article we’ll go over the elements that make up an electric 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

An electrical system is comprised of several important components that work to supply power to homes. They include:

Breaker box is the central source of electrical power in homes, where the electricity is divided into different circuits

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

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

Electric appliances, devices and equipment: appliances and gadgets that rely on electricity to function.

Electrical Circuits

An electrical circuit is a pathway which allows electricity to flow from the point of origin (the breakers box) to the devices and appliances in the home. There are two types of electrical circuits in a home that are 120-volt and 240-volt circuits. 120-volt circuits are utilized for the majority of household appliances 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 a loop that allows electricity to be transferred from the source to the device or appliance. The loop is comprised of a hot wire that is the conduit for electricity and a neutral wire which completes the circuit as well as a ground wire that provides a path for electricity to travel to the ground in the event the fault occurs.

Understanding Electrical Wiring

Electrical wiring is available in a variety of kinds, such as non-metallic sheathed cable (NM) and armored cable (AC) and conduit. Each type has its advantages and disadvantages and the selection of the type of wiring is based on the specific requirements of the installation.

Wiring conducts electricity through a flow of electrons that travel through the wire. Electrons move through the wire from source, to appliance or device returning to the source using the neutral wire. It is crucial to make sure that the wiring is put in place and maintained correctly, as improper wiring can cause electrical hazards like shocks and fires.

Common Electrical Issues

Some common electrical problems that homeowners face include tripping the light bulbs, flickering breakers and electrical outlets that are not working. These issues can be caused due to a variety of reasons such as overloading circuits loose connections, and faulty wiring.

If you are experiencing any of these issues, it’s essential to identify the source and take actions to rectify the issue. In certain instances this could mean contacting an accredited electrician to look over and fix the wiring.
