Electricity is an integral part of our life, powering everything from the lighting in our houses to gadgets we use every day.  However, electrical systems can be a bit complicated, making it difficult to understand how they function isn’t easy. In this article we’ll go over the components 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

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

Breaker box is the central distribution point for electric power in a home that is where electricity is split into various circuits

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

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

Electronic appliances and gadgets: the devices and appliances that use electricity to function.

Electrical Circuits

A circuit of electricity is one that lets electricity flow from the point of origin (the the breaker box) to the appliances and devices in a home. There are two kinds of electrical circuits found in homes which are 120-volt circuits and circuits with 240-volt voltage. 120-volt circuits are employed to power most household appliances and appliances, while 240-volt circuits are used to power larger appliances, such as air conditioners and electric dryers.

Electrical circuits work by completing an electrical loop that allows power to flow from the source to the device or appliance. The loop is made up of a hot cable that transports the power, a neutral wire that completes the circuit, and a ground wire , which is a path for the electricity to get to the ground in the event of a fault.

Understanding the electrical Wiring

Electrical wiring is available in a variety of kinds, such as non-metallic sheathed cable (NM) and armored cable (AC), and conduit. Each kind comes with its own pros and drawbacks and the selection of the wiring type is contingent upon the specific needs of the installation.

Electricity travels through wiring through a flow of electrons in the wire. Electrons move between the origin and the device or appliance returning to the source via the neutral wire. It’s essential to ensure that the wiring is installed and maintained properly, since improper wiring can cause electrical hazards such as shocks or fires.

Common Electrical Issues

The most frequent electrical problems found that homeowners face include tripping the breakers, flickering lights and dead outlets. The causes of these issues could be by a variety of factors that include overloading circuits, broken connections, and defective wiring.

If you’re experiencing any of these issues, it’s crucial to pinpoint the cause and take appropriate actions to rectify the issue. In some cases, this may involve contacting a licensed electrician to examine and fix the wiring.
