Electricity is an integral part of our everyday life, powering everything from the lights of our houses to gadgets we use every day.  However, electricity systems are a bit complicated, making it difficult to understand how they work can be difficult. In this article we’ll breakdown the various components 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 the home. This includes:

Breaker box is the central distribution point for electric energy in a house in which the power is divided into several circuits

Outlets and switches: the points where electricity is delivered to devices and appliances

Wiring: the electrical wires that carry power from the breaker box, to the outlets and switches

Electrical appliances and devices: appliances and gadgets that rely on electricity for their functions.

Electrical Circuits

The term "electrical circuit" refers to a path which allows electricity to flow from the source (the breaker box) to the devices and appliances in a home. There are two kinds of electrical circuits found in a home which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are used for most household devices and appliances, whereas the 240-volt circuits are utilized for larger appliances like dryers, air conditioners and electric ones.

Electrical circuits work by creating an electrical loop that allows power to be transferred from the source to the device or appliance. The loop is made up of a hot cable that is the conduit for electricity, a neutral wire that completes the circuit, and the ground wire which provides the pathway for electricity to reach the ground in the event of a fault.

Understanding Electrical Wiring

Electrical wiring is available in a variety of different types, including non-metallic sheathed cable (NM) and armored cable (AC), and conduit. Each type comes with its own pros and disadvantages and the selection of the type of wiring is based on the specific needs of the installation.

Electricity travels through wiring through the creation of electrons through the wire. The electrons travel through the wire from source, to device or appliance and then back to the source using the neutral wire. It is crucial to make sure that the wiring is put in place and maintained in a correct manner, as defective wiring could lead to electrical dangers like shocks and fires.

Common Electrical Issues

The most frequent electrical problems found in homes include tripping breakers, flickering lights, and dead outlets. The causes of these issues could be by a myriad of causes, including overloading circuits, poor connections, or 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 instances this could mean contacting an authorized electrician to look over and fix the wiring.

Concluding as well as a Call to Action
