Electricity is an integral part of our daily lives, powering everything from the lights in our homes to the appliances we use on a daily basis.  But electrical systems can be complex and understanding how they function can be difficult. In this guide we’ll go over the various 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.

The components of an electrical system

An electrical system has several important components that work to provide power throughout a home. These include:

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

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

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

Electrical appliances and devices: the appliances and devices that require electricity to function.

Electrical Circuits

The term "electrical circuit" refers to one that allows electricity to flow from the source (the breaker box) to appliances and devices within the home. There are two kinds of electrical circuits in homes: 120-volt circuits and circuits that are 240-volts. 120-volt circuits are utilized for most household devices and appliances, while 240-volt circuits are used to power larger appliances, such as dryers and air conditioners.

Electrical circuits work by completing the loop which allows electricity to flow from the source into the device or appliance. The loop consists of a hot wire that is the conduit for electricity and a neutral wire which completes the circuit as well as a ground wire that provides a path for electricity to travel to the ground in the event there is a problem.

Understanding Electrical Wiring

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

Wiring conducts electricity through a flow of electrons that travel through the wire. The electrons flow from the source to the device or appliance and then back to the source using the neutral wire. It is crucial to make sure that the wiring is put in place and maintained properly, since improper wiring can cause electrical hazards like shocks and fires.

Common Electrical Problems

Common electrical issues in homes include tripping breakers, flickering lights, and electrical outlets that are not working. The causes of these issues could be by a myriad of causes, including overloading circuits, broken connections, and defective wiring.

If you are experiencing one of these problems, it is essential to determine the source and take steps to correct the issue. In certain instances this could mean contacting a licensed electrician to examine and fix the wiring.
