Electricity is a vital part of our daily life, powering everything from the lighting in our houses to devices we use every day.  However, electricity systems are complex, and understanding how they work can be challenging. In this guide, we’ll break down 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

An electrical system is comprised of several essential components that work to provide power throughout a home. This includes:

Breaker box is the central distribution point for electrical energy in a house that is where electricity is divided into different circuits

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

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

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

Electrical Circuits

The term "electrical circuit" refers to a path that lets electricity flow from the main source (the breakers box) to the devices and appliances in a home. There are two kinds of electrical circuits in the home: 120-volt circuits and 240-volt circuits. 120-volt circuits are utilized for most household devices and appliances, while the 240-volt circuits are utilized for larger appliances like dryers, air conditioners and electric ones.

Electrical circuits function by creating a loop that allows electricity to flow from the source to the device or appliance. The loop is comprised of a hot cable that transports the power, a neutral wire that completes the circuit, and the ground wire which provides a path for electricity to travel to the ground in the event the fault occurs.

Understanding Electrical Wiring

Electrical wiring comes in several kinds, such as non-metallic sheathed cable (NM) as well as armored cables (AC) and conduit. Each kind has its own advantages and disadvantages, and the choice of wiring type depends on the specific requirements that the location requires.

Wiring conducts electricity by creating a flow of electrons that travel through the wire. The electrons travel through the wire from source, to appliance or device returning to the source using the neutral wire. It is essential to ensure the wiring is put in place and maintained in a correct manner, as improper wiring can cause electrical dangers like shocks and fires.

Common Electrical Issues

The most frequent electrical problems found that homeowners face include tripping the light bulbs, flickering breakers and electrical outlets that are not working. The causes of these issues could be by a myriad of causes, including overloading circuits, poor connections, or faulty wiring.

If you are experiencing one of these problems, 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 inspect and repair the wiring.
