Electricity is an essential component of our lives, supplying everything from the lighting in our homes to the gadgets we use on a daily basis.  But electricity systems are complex making it difficult to understand how they function can be challenging. In this guide, we’ll break down the elements of an electrical system, and explain how circuits work to power appliances and devices. Our residential electricians can handle any electrical jobs you need.

The components of an electrical system

An electrical system is comprised of several important components that work to supply power to the home. They include:

Breaker box: the main distribution point for electric power in homes, where the electricity is split into various circuits

Switches and outlets: the places where electricity is delivered to devices and appliances

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

Electronic appliances and gadgets: the appliances and devices that require electricity to function

Electrical Circuits

The term "electrical circuit" refers to a pathway which allows electricity to flow from the point of origin (the the breaker box) to the devices and appliances in the home. There are two types of electrical circuits that can be found in a home which are 120-volt circuits and 240-volt circuits. 120-volt circuits are used to power most household appliances and appliances, while the 240-volt circuits are designed to power larger appliances, such as air conditioners and electric dryers.

Electrical circuits function by creating the loop which allows electricity to be transferred from the source to the device or appliance. The loop is made up of a hot cable that carries the electricity, a neutral wire that completes the circuit and a ground wire , which is the pathway for electricity to travel to the ground in case there is a problem.

Understanding the electrical Wiring

Electrical wiring is available in many different kinds, including non-metallic sheathed cables (NM), armored cable (AC) and conduit. Each has its advantages and disadvantages and the selection of wiring type depends on the specific requirements for the particular installation.

Wiring conducts electricity by creating a flow of electrons through the wire. Electrons move from the source to the appliance or device, and back to the source using 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 that homeowners face include tripping the breakers, flickering lights and dead outlets. These issues can be caused by a myriad of causes such as overloading circuits loose connections, and faulty wiring.

If you are experiencing one of these problems, it is essential to determine the root cause and take action to fix the problem. In some cases it may be necessary to contact a licensed electrician to examine and fix the wiring.
