Electricity is a vital part of our daily life, powering everything from the lighting in our homes to the gadgets we use on a daily basis.  However, electricity systems are complex, and understanding how they function isn’t easy. In this guide we’ll go over the elements of an electrical system, and show how circuits operate to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

Components of an Electrical System

A home’s electrical system includes a number of important components that work to provide power throughout the home. These include:

Breaker box is the central distribution point for electrical energy in a house, where the electricity is divided into several circuits

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

Wiring: the electrical wires that transmit electric current from the box to outlets and switches

Electric appliances, devices and equipment: the appliances and devices that require electricity for their functions.

Electrical Circuits

The term "electrical circuit" refers to a path which allows electricity to flow from the source (the breakers box) to the devices and appliances in the home. There are two types of electrical circuits found in homes which are 120-volt circuits and circuits that are 240-volts. 120-volt circuits are employed to power most household appliances and appliances, whereas the 240-volt circuits are utilized for larger appliances such as dryers and air conditioners.

Electrical circuits function by creating an electrical loop that allows power to flow from the source into the device or appliance. The loop consists of a hot cable that is the conduit for electricity and a neutral wire which completes the circuit, and the ground wire which provides an avenue for electricity to travel to the ground in the event of a fault.

Understanding Electrical Wiring

Electrical wiring is available in a variety of kinds, such as non-metallic sheathed cable (NM) as well as armored cables (AC), and conduit. Each kind comes with its own pros and disadvantages, and the choice of wiring type depends on the specific requirements that the location requires.

Wiring conducts electricity by creating a flow of electrons in the wire. The electrons flow through the wire from source, to device or appliance and then back to the source via the neutral wire. It is essential to ensure the wiring is put in place and maintained correctly, as improper wiring can cause electrical hazards like shocks and fires.

Common Electrical Issues

Some common electrical problems in homes include tripping light bulbs, flickering breakers and electrical outlets that are not working. These issues can be caused by a myriad of causes such as overloading circuits poor connections, or faulty wiring.

If you experience any of these issues it’s crucial to pinpoint the root cause and take steps to correct the issue. In certain instances, this may involve contacting an authorized electrician to examine and fix the wiring.
