Components of an Electrical System

An electrical system is comprised of several essential components that work to provide power throughout the home. These include:

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

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

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

Electric appliances, devices and equipment: the appliances and devices that require electricity to function

Electrical Circuits

An electrical circuit is a pathway which allows electricity to flow from the source (the breaker box) to the devices and appliances in a home. There are two kinds of electrical circuits that can be found in a home that are 120-volt and circuits with 240-volt voltage. 120-volt circuits are used for most household devices and appliances, while the 240-volt circuits are utilized for larger appliances such as air conditioners and electric dryers.

Electrical circuits work by creating an electrical loop that allows power to flow from the source into the appliance or device. The loop is made up of a hot cable that carries the electricity along with a neutral wire that completes the circuit as well as a ground wire that provides the pathway 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 cables (NM) as well as armored cables (AC) and conduit. Each type comes with its own pros and disadvantages and the selection of the type of wiring is based on the specific needs for the particular installation.

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

Common Electrical Issues
