Electricity is an integral part of our everyday lives, supplying everything from the lights in our houses to gadgets we use on a daily basis.  However, electric systems may be complicated, and understanding how they function isn’t easy. In this guide we’ll breakdown the various components 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.

The components of an electrical system

An electrical system has several key components that work together to deliver power throughout homes. This includes:

Breaker box: the main distribution point for electrical power in a home, where the electricity is split into various circuits

Switches and outlets: places where electricity is delivered to devices and appliances

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

Electric appliances, devices and equipment: appliances and gadgets that rely on electricity to function.

Electrical Circuits

The term "electrical circuit" refers to a pathway that allows electricity to flow from the source (the the breaker box) to the devices and appliances in a home. There are two types of electrical circuits found in the home which are 120-volt circuits and circuits with 240-volt voltage. 120-volt circuits are utilized for the majority of household appliances and appliances, whereas the 240-volt circuits are utilized for larger appliances such as dryers and air conditioners.

Electrical circuits work by completing a loop that allows electricity to flow from the source to the device or appliance. The loop is comprised of a hot wire which carries the electricity and a neutral wire which completes the circuit, and a ground wire that provides a path for the electricity to get to the ground in case there is a problem.

Understanding Electrical Wiring

Electrical wiring is available in a variety of different types, including non-metallic sheathed wire (NM), armored cable (AC), and conduit. Each kind has its own advantages and drawbacks and the selection of the type of wiring is based on the specific needs for the particular installation.

The electricity travels through wires through a flow of electrons through the wire. The electrons flow from the source to the appliance or device returning to the source using the neutral wire. It’s essential to ensure that the wiring is installed and maintained properly, since improper wiring can cause electrical dangers like shocks and fires.

Common Electrical Problems

Common electrical issues in homes include tripping light bulbs, flickering breakers and disconnected outlets. The causes of these issues could be by a variety of factors that include overloading circuits, loose connections, and faulty wiring.

If you experience one of these problems, it’s crucial to pinpoint the cause and take appropriate action to fix the problem. In some cases this could mean contacting an accredited electrician to examine and fix the wiring.
