Electricity is an integral part of our life, powering everything from the lighting in your homes, to gadgets that we use each day.  But electricity systems are complicated and understanding how they operate can be challenging.

Components of an Electrical System

An electrical system is comprised of several key components that work together to deliver power throughout a home. These include:

Breaker box is the central distribution point for electric power in a home, where the electricity is split into various circuits

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

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

Electrical appliances and devices: the appliances and gadgets that rely on electricity to function

Electrical Circuits

A circuit of electricity is one which allows electricity to flow from the main source (the the breaker box) to appliances and devices within the home. There are two kinds of electrical circuits that can be found in homes that are 120-volt and circuits that are 240-volts. 120-volt circuits are utilized for most household devices and appliances, whereas the 240-volt circuits are designed to power larger appliances, such as dryers and air conditioners.

Electrical circuits work by creating an electrical loop that allows power to flow from the source to the appliance or device. The loop is made up of a hot wire that carries the electricity, a neutral wire that completes the circuit and the ground wire which provides an avenue for electricity to reach the ground in case there is a problem.

Understanding Electrical Wiring

Electrical wiring is available in many different kinds, including non-metallic sheathed cable (NM) as well as armored cables (AC) and conduit. Each has its advantages and disadvantages and the selection of the wiring type is contingent upon the particular requirements for the particular installation.

The electricity travels through wires through the creation of electrons in the wire. Electrons move from the source to the appliance or device and then back to the source through 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 that homeowners face include tripping the breakers, flickering lights and electrical outlets that are not working. The causes of these issues could be by a myriad of causes such as overloading circuits poor connections, or faulty wiring.

If you experience any of these issues, it is essential to determine the source and take steps to correct the issue. In some instances, this may involve contacting an accredited electrician to look over and fix the wiring.
