How does electrical grounding work?

electrical grounding wire

In any electrical circuit, there’s an active wire that supplies you with power, a neutral wire which carries this current back, and a third wire known as a ‘grounding wire’, which offers an extra path for the electrical current to return safely into the ground. In other words, electrical grounding is your backup if there is a fault or problem within your wiring system. You’ll want to ensure that your electrical systems are all grounded properly so that your home and loved ones are not put at any unnecessary risk. This article will be looking at how electrical grounding works and why it’s important for your safety.

 

Why is electrical grounding important?

There are a number of important reasons why electrical grounding is essential in any electrical system. If there is a problem with your neutral wire, the grounding of your electrical system will offer a direct and safe path to the ground to prevent power surges which can create other electrical dangers.

 

EARTH IS A GREAT CONDUCTOR

The reason that you need to make sure that your electrical appliances are properly grounded is that the earth itself is a quality conductor that can conduct all of the excess electricity with the least resistance. By grounding your electrical system, and connecting it directly to the earth, you’ll be providing the excess electricity in the system with somewhere to go without resistance, meaning that it won’t go through your appliances or you instead.

 

PROTECTING AGAINST ELECTRICAL OVERLOADS 

Electrical power surges can happen to any home for a number of different reasons. These events may lead to an enormous amount of electricity being produced, which can result in some serious damage to your electrical appliances. If your electrical system is grounded, all of this excess electricity caused by the power surge will head into the earth, instead of completely destroying your appliances connected to power. This is the easiest way to make sure your devices and appliances are all safe and sound in the event of an electrical overload.

 

STABILISING VOLTAGE LEVELS

Making sure that the correct amount of power is appropriately distributed to the right places around your home is one of the great benefits of grounding your electrical system. This can help in ensuring that you aren’t overloading or blowing your circuits at home. The earth is typically considered as a common reference point for the different voltage sources in your electrical system.

 

REDUCING RISK OF INJURIES 

We all do what we can to reduce the risk of injuries in our life, and without grounding your electrical system, you’re putting more than your appliances at risk. In the event that a large amount of electricity passes through an appliance or device, it will completely fry the device. In some cases, if this amount of electricity is substantial, there is a risk that it could start a fire. You could be putting your home and your loved ones at an unnecessary level of risk by not grounding your electrical system.

 

How do I know if my current is grounded?

Many appliances and electrical devices have a grounding system for safety. The easy way of checking whether an electrical appliance is designed to be grounded is to check whether it has a three-pronged plug and a three-wire cord. These components provide the ground link between the appliance’s metal frame and the grounding of the wired system.

 

If your electrical power outlets have space for three prongs, this is usually a sign that your electrical system has a third wire for grounding. If you’d like to be assured of whether your system is grounded or not, you can hire an electrician Perth to conduct an electrical grounding test.

 

Testing for Electrical Grounding

Testing for electrical grounding at home should be done by a licensed and experienced electrician. Not only can they detect whether your system is grounded, but they can also check your appliances to see if any old or frayed wires may be putting your home at risk. The electricians at Scott Comms are here to keep your homes safe and will always ensure that your electrical system is in a healthy and safe condition.

 

If you are living in an older home, electrical contractors Perth can also advise you on whether a home rewire will be more beneficial to get your electrical system properly set up to meet the demands of the household.
