Electricity is a vital part of our lives, supplying everything from the lights of our homes to the gadgets we use on a daily basis.  However, electricity systems are a bit complicated, knowing how they work can be difficult. In this guide we’ll breakdown 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 has several key components that work together to supply power to homes. These include:

Breaker box: the central distribution point for electric energy in a house, where the electricity is split into various circuits

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

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

Electronic appliances and gadgets: the appliances and gadgets that rely on electricity to function.

Electrical Circuits

The term "electrical circuit" refers to a pathway which allows electricity to flow from the point of origin (the breakers box) to appliances and devices within the home. There are two kinds of electrical circuits in homes which are 120-volt circuits and circuits with 240-volt voltage. 120-volt circuits are used to power most household appliances and appliances, whereas the 240-volt circuits are designed to power larger appliances, such as 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 consists of a hot cable that carries the electricity, a neutral wire that completes the circuit and a ground wire that provides an avenue for electricity to travel to the ground in case the fault occurs.

Understanding Electrical Wiring

Electrical wiring comes in several different kinds, including non-metallic sheathed cables (NM) and armored cable (AC), and conduit. Each kind comes with its own pros and drawbacks, and the choice of wiring type depends on the specific requirements for the particular installation.

Electricity travels through wiring through a flow of electrons through the wire. The electrons flow between the origin and the device or appliance returning to the source through 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 dangers like shocks and fires.

Common Electrical Problems

Some common electrical problems in homes include tripping breakers, flickering lights, and disconnected outlets. These issues can be caused due to a variety of reasons, including overloading circuits, loose connections, and faulty wiring.

If you are experiencing any of these issues it is essential to determine the root cause and take actions to rectify the issue. In certain instances this could mean contacting an accredited electrician to inspect and repair the wiring.
