Electricity is an integral part of our life, powering everything from the lights of your homes, to appliances we use every day.  But electrical systems can be complex knowing how they function can be challenging. In this article we’ll go over the components that make up an electric system, and describe how circuits function to power appliances and devices. Our residential electricians can handle any electrical jobs you need.

The components of an electrical system

A home’s electrical system includes a number of essential components that work to supply power to a home. This includes:

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

Outlets and switches: the 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: appliances and devices that require electricity to function

Electrical Circuits

A circuit of electricity is one that lets electricity flow from the main source (the the breaker box) to appliances and devices within the home. There are two types of electrical circuits found in a home which are 120-volt circuits and 240-volt circuits. 120-volt circuits are employed for the majority of household appliances and appliances, while the 240-volt circuits are designed for larger appliances like dryers, air conditioners and electric ones.

Electrical circuits function by creating an electrical loop that allows power to flow from the source into the appliance or device. The loop consists of a hot wire which transports the power and a neutral wire which completes the circuit, and the ground wire which provides the pathway for the electricity to get to the ground in the event of a fault.

Understanding the electrical Wiring

Electrical wiring comes in several different types, including non-metallic sheathed cable (NM) as well as armored cables (AC) and conduit. Each has its own advantages and disadvantages, and the choice of the type of wiring is based on the particular requirements of the installation.

Electricity travels through wiring through a flow of electrons through the wire. Electrons move between the origin and the device or appliance and then back to the source through the neutral wire. It is crucial to make sure that the wiring is put in place and maintained correctly, as defective wiring could lead to electrical hazards like shocks and fires.

Common Electrical Problems

Common electrical issues at home include tripping light bulbs, flickering breakers and disconnected outlets. These problems can be caused by a myriad of causes that include overloading circuits, broken connections, and defective wiring.

If you’re experiencing one of these problems, it’s essential to identify the cause and take appropriate steps to correct the issue. In some instances it may be necessary to contact a licensed electrician to look over and fix the wiring.
