Whole house surge protection – the facts that you should know

Whole house surge protection is something that many house builders are now offering as an optional add on. If you are buying a new build it’s worth investing in the protection that these whole house systems offer. Likewise, if you already have a property, it’s worth having whole house surge protection installed. Doing so could end up saving you thousands of dollars.

Next time you have an electrical inspection carried out on your property, ask the experts about installing whole house surge protection. Generally, you should expect to pay between AUS$600 and AUS$700. The job should take a qualified electrician around two hours to complete.

Why is whole house surge protection a good idea?

If a surge of electricity enters your home it can potentially cause thousands of dollars’ worth of damage. Electronic items, such as computers, used to be worst affected by this type of event. Whilst computers are still vulnerable, they have now been joined by a long list of day to day appliances. Do not forget that items such as refrigerators now often have complicated circuitry which can easily be blown by a power surge.

The worst type of power surge is one that is caused by a lightning strike, as this type of surge is massive. Fortunately, this is a relatively rare occurrence, and the lightning has to strike within a mile of your property in order for a surge to happen.

Power surges can also be caused by events such as power cables falling down or the amount of electricity being used in the neighbored fluctuating suddenly. Any power surge has the potential to cause damage, so it’s worth having protection in place.

Using individual circuit surge suppressors

Even if you use whole house surge protection, there is still a chance that around 15% of the electric from the surge will get through to appliances. This is why it’s a good idea to use individual circuit surge suppressors as well. These plug-in suppressors help to protect the most vulnerable appliances and devices in your home.

Normally, electricity flows through the suppressor, on its way to the appliance or device. If a surge in electricity occurs, the electricity is diverted to the ground wire. As soon as the surge is over, the electricity starts to flow normally again. Do not forget that all of this often happens in less than a second.

The best way to protect your home and its contents against surges in electricity is to use whole house and individual circuit protection, at the same time. You may think that all of this sounds like a lot of trouble when you have never had a problem from an electricity surge. The fact is that these surges are quite common, and it’s better to have the protection in place. You may not even realise that you have had problems in the past, as not all results of damage are obvious instantaneously. It can take months for a device to fail due to damage caused by a surge in electricity.

You can guard against these failures, by simply having surge protection in place.
