Electricity is an integral part of our everyday life, powering everything from the lighting in our houses to gadgets that we use each day.  But electrical systems can be complex, knowing how they operate isn’t easy. In this guide we’ll go over the various components in an electrical circuit, and describe how circuits function to power appliances and devices. Our residential electricians can handle any electrical jobs you need.

The components of an electrical system

A home’s electrical system includes a number of important components that work to supply power to a home. They include:

Breaker box: the main distribution point for electrical power in a home in which the power is divided into different circuits

Outlets and switches: the points at which electricity is supplied to devices and appliances

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

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

Electrical Circuits

An electrical circuit is a pathway that lets electricity flow from the source (the the breaker box) to the appliances and devices in the home. There are two types of electrical circuits that can be found in a home that are 120-volt and circuits that are 240-volts. 120-volt circuits are used for most household devices and appliances, while 240-volt circuits are used for larger appliances like dryers, air conditioners and electric ones.

Electrical circuits work by completing a loop that allows electricity to flow from the source into the device or appliance. The loop is made up of a hot wire that carries the electricity and a neutral wire which completes the circuit as well as a ground wire that provides the pathway for the electricity to get to the ground in the event the fault occurs.

Understanding the electrical Wiring

Electrical wiring is available in a variety of different types, including non-metallic sheathed cable (NM), armored cable (AC) and conduit. Each has its advantages and drawbacks and the selection of the type of wiring is based on the specific requirements 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 using the neutral wire. It is crucial to make sure that the wiring is installed and maintained properly, since improper wiring can cause electrical dangers like shocks and fires.

Common Electrical Problems

The most frequent electrical problems found in homes include tripping light bulbs, flickering breakers and dead outlets. These problems can be caused by a variety of factors such as overloading circuits poor connections, or faulty wiring.

If you experience any of these issues, it’s essential to identify the cause and take appropriate steps to correct the issue. In certain instances, this may involve contacting a licensed electrician to look over and fix the wiring.
