Electricity is an essential component of our everyday lives, supplying everything from the lights of our homes to the appliances that we use each day.  But electricity systems are complicated, knowing how they function isn’t easy. In this guide we’ll breakdown the components in an electrical circuit, and explain how circuits work to power appliances and devices. Our residential electricians can handle any electrical jobs you need.

Components of an Electrical System

An electrical system has several important components that work to provide power throughout homes. They include:

Breaker box: the central source of electrical power in homes in which the power is split into various circuits

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

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

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

Electrical Circuits

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

Electrical circuits function by creating an electrical loop that allows power to be transferred from the source to 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 as well as the ground wire which provides the pathway for the electricity to get to the ground in case there is a problem.

Understanding Electrical Wiring

Electrical wiring is available in many different types, including non-metallic sheathed cables (NM), armored cable (AC), and conduit. Each has its advantages and drawbacks and the selection of wiring type depends on the specific needs that the location requires.

Wiring conducts electricity through the creation of electrons that travel through the wire. Electrons move through the wire from source, to appliance or device returning to the source via the neutral wire. It is essential to ensure the wiring is put in place and maintained properly, since defective wiring could lead to electrical hazards like shocks and fires.

Common Electrical Issues

Common electrical issues that homeowners face include tripping the breakers, flickering lights, and electrical outlets that are not working. These issues can be caused by a myriad of causes, including overloading circuits, poor connections, or faulty wiring.

If you’re experiencing any of these issues, it is essential to determine the root cause and take steps to correct the issue. In some cases, this may involve contacting a licensed electrician to examine and fix the wiring.
