What Does a Surge Protector Do?


Surge protectors are a significant investment in today’s time, where every appliance and device is electronic and has to be plugged in.


More often than not, every home has more electronic appliances and devices as compared to the number of convenient outlets. That is why you usually end up needing a couple of extra outlets for your devices.


So, what does a surge protector do? Well, surge protectors have the ability to protect either one single outlet or the whole house. Most, if not all expert electricians recommend that surge protectors should be in place in residential homes.


Here’s everything you should be aware of to understand how surge protectors work in order to protect your electronics.


Why Do You Need a Surge Protector?


Perhaps you already have a surge protector in your home, or you might have been told that it’s high time to invest in one. Regardless, you might not have a full understanding of what a surge protector does.


In comparison to a regular power bar, a surge protector ensures that your devices are protectors from power surge damage. On a larger scale, a surge protector can in fact protect the entire home from a power surge.


What is a Surge Protector Capable of Doing?


Essentially, a surge protector detects the sudden surge of power or voltage and disperses it. In the instance that a power surge flows freely, as it does without a surge protector, it will essentially fry your electronics.


Surge protectors have a number of different important jobs. These jobs differ in point-of-use protectors and whole-house surge protectors. Here are the general tasks that surge protectors or capable of doing:


Pressure Management


Managing the electric pressure within the house is the most important thing a surge protector does. In other words, a surge protector’s primary job is to manage the electricity pressure in an outlet or home.



This ensures that no electronic device is being damaged by an electricity surge. And, why is this important? Although in some situations you can anticipate a power surge, such as during a thunderstorm, it’s not always possible to switch off electronics at that specific time.


In fact, let’s not forget that power surges can happen at almost any time out of the blue.


Whole-House Surge Protection


The job of a surge protector ultimately depends on the type of protection it offers. A whole-house surge protector is installed in two prominent ways: between your street’s power lines and the home’s electrical meter and between the electrical meter and the break box of a home.


Single Surge Protector


This type of surge protector is installed right at the outlet itself. It usually gives you the ability to add more outlets than the typical number of outlets coming from the wall. Moreover, they are equipped with technology that diverts all the extra power away from the outlet.




It’s important that you note that the two types of surge protectors ought to be used in tandem. In all honesty, none of the two surge protectors are that capable of amazing a power surge in its entirety.


Therefore, they can work off of one another to make sure that no extra power is able to get through and that it’s well managed by the other protector.




If you weren’t aware, surge protectors also cover the cost of electronics damaged by a power surge. That is only if the units were in use at that point in time. Their job is to offer protection to your electronics from a power surge.



This further means that, if a power surge was able to cause damage to your electronics, the company ought to be able to have them replaced.



How is a Surge Protector’s Power Measured?



Surge protectors use joules for their measurement of energy. The higher the joules of a surge protector, the better the protection it offers. The more a surge protector is used, the faster the house of the protectors breaks down.


This requires you to replace the protectors to ensure that all your electronics are well protected. Unfortunately, there’s no obvious way of measuring the holes “left” in the surge protection, it’s purely based on guesswork


Your best bet would be to replace the surge protector every couple of years. That said, if there are frequent power surges in your home, you might want to consider replacing them earlier.



Well, there you go! We hope we’ve managed to answer all your questions regarding surge protectors. Surge protectors are a necessity for your household if you want no harm to come to your electronics because all electronics are very much of an investment.
