Electricity is an essential component of our everyday life, powering everything from the lights in our houses to devices we use every day.  But electric systems may be a bit complicated and understanding how they work isn’t easy. In this article we’ll go over the components in an electrical circuit, and show how circuits operate 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 supply power to a home. This includes:

Breaker box: the central distribution point for electrical power in a home, where the electricity is divided into several circuits

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

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

Electric appliances, devices and equipment: devices and appliances that use electricity for their functions.

Electrical Circuits

An electrical circuit is a path that lets electricity flow from the source (the breaker box) to appliances and devices within the home. There are two kinds of electrical circuits that can be found in homes that are 120-volt and 240-volt circuits. 120-volt circuits are employed for most household devices and appliances, whereas the 240-volt circuits are utilized for larger appliances such as dryers, air conditioners and electric ones.

Electrical circuits work by completing a loop that allows electricity to be transferred from the source to the appliance or device. The loop consists of a hot cable that carries the electricity, a neutral wire that completes the circuit as well as a ground wire , which is an avenue for the electricity to get to the ground in case the fault occurs.

Understanding 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 has its own advantages and disadvantages, and the choice of the wiring type is contingent upon the particular requirements of the installation.

The electricity travels through wires through the creation 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’s essential to ensure that the wiring is installed and maintained correctly, as defective wiring could lead to electrical dangers like shocks and fires.

Common Electrical Problems

Some common electrical problems that homeowners face include tripping the breakers, flickering lights, and electrical outlets that are not working. The causes of these issues could be by a myriad of causes that include overloading circuits, poor connections, or faulty wiring.

If you experience one of these problems, it is essential to determine the source and take steps to correct the issue. In some instances, this may involve contacting a licensed electrician to look over and fix the wiring.
