The components of an electrical system

An electrical system has several key components that work together to provide power throughout the home. They include:

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

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

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

Electrical Circuits

A circuit of electricity is a path that allows electricity to flow from the main source (the the breaker box) to appliances and devices within a home. There are two kinds of electrical circuits in a home which are 120-volt circuits and 240-volt circuits. 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 function by creating a loop that allows electricity to flow from the source to the appliance or device. The loop is comprised of a hot wire which carries the electricity, a neutral wire that completes the circuit as well as the ground wire which provides an avenue for the electricity to get to the ground in case there is a problem.

Understanding Electrical Wiring

Electrical wiring is available in many kinds, such as non-metallic sheathed cable (NM) and armored cable (AC), and conduit. Each comes with its own pros and drawbacks and the selection of the type of wiring is based on the specific requirements of the installation.

Wiring conducts electricity through a flow of electrons in the wire. The electrons flow between the origin and the appliance or device, and back to the source through the neutral wire. It is crucial to make sure that the wiring is installed and maintained in a correct manner, as improper wiring can cause electrical dangers like shocks and fires.
