Electricity is an essential component of our daily lives, powering everything from the lights in our homes to the devices we use every day.  However, electric systems may be complex knowing how they function can be difficult. In this guide, we’ll break down the components in an electrical circuit and describe how circuits function 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 essential components that work to provide power throughout the home. They include:

Breaker box: the main distribution point for electrical energy in a house that is where electricity is split into various circuits

Switches and outlets: the points at which electricity is supplied to appliances and devices

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

An electrical circuit is a path that lets electricity flow from the source (the the breaker box) to the devices and appliances in a home. There are two kinds of electrical circuits in a home which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are used to power most 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 completing the loop which allows electricity to flow from the source to the device or appliance. The loop is made up of a hot wire which carries the electricity and a neutral wire which completes the circuit and the ground wire which provides the pathway for the electricity to get to the ground in case there is a problem.

Understanding the electrical Wiring

Electrical wiring comes in several different types, including non-metallic sheathed cable (NM) as well as armored cables (AC), and conduit. Each kind has its own advantages and disadvantages and the selection of the type of wiring is based on the specific needs of the installation.

The electricity travels through wires through the creation of electrons that travel through the wire. Electrons move through the wire from source, to appliance or device returning to the source via the neutral wire. It’s essential to ensure that the wiring is installed and maintained in a correct manner, as faulty wiring can lead to electrical hazards like shocks and fires.

Common Electrical Problems

Common electrical issues that homeowners face include tripping the light bulbs, flickering breakers and disconnected outlets. The causes of these issues could be by a myriad of causes that include overloading circuits, loose connections, and faulty wiring.

If you’re experiencing any of these issues, it’s essential to identify the root cause and take steps to correct the issue. In some cases it may be necessary to contact a licensed electrician to inspect and repair the wiring.
