Whole House Surge Protection / Whole Home Surge Protection

Today, the concept of whole house surge protection or whole home surge protection is becoming more and more popular. One of the important reasons is that today there are too many electronic devices that are very expensive yet very vulnerable to power surges. It is estimated that an average house contains more than USD 15000 electronic and electrical products that are unprotected from surges. A typical surge attack may leave all the electronic and electric devices paralyzed and that’s the case you never want to experience.

So in this article, we are going to talk about this subject: whole house surge protection.

Why we need whole house surge protection?

Surge is a very common danger to home appliances. If you live in a area with frequent lightning strikes, you may already suffer from the damages it brings. Here are the stories from two victims. Does it sound similar to you?

Let’s look at some pictures of surge damage. Actually, these are moderate damages. In some mission-critical section like oil & gas, railway system, surge can cause disasters.

Common Misunderstandings of Whole House Surge Protection

Yet there are some common misunderstandings about whole house surge protection.

Misunderstanding 1: I live in an area with very low frequent lightning activity. I think the the possibility of my house hit by a lightning is close to zero. Thus, I don’t think my house need surge protection.

Our advice is: don’t gamble on the bets. Though the chance of be hit by a direct lightning is indeed very low. The possibility of being attack by surge is far more higher than most people expected. For one thing, surge is only caused by direct lightning hit. A nearby lightning hit can cause a very strong surge into your house too. Another important idea that are often overlooked is that, most surges are actually generated inside your house, for example, the on and off switch of a motor. These surges are frequent and with lower energy and they may not be able to destroy your home electronics at one time. But it degrades them over time and shorten their lifespan.

Misunderstanding 2: I already have a power strip with surge protection function connected to my appliance. It is already safe enough.

When we talk about surge protector, maybe most people only refer to a power strip or receptacle which look like this. Yet the problem with these surge strip or surge protector, whatever you call it, is that they either provide no protection or very low level protection to surges. When a strong surge attack, even the surge strip will be damaged and even burnt. In this case, they only give you a false sense of security.

How to Set up a Safe & Sound Whole House Surge Protection?

Since we are a child, we’ve been instructed to plug off all electronic devices during thunderstorm. It did help as surge often travels through power lines. But nowadays, as we have more and more electronic devices and plug off all of them seems unrealistic. As we discussed, just connecting a surge strip to the protected device is far from enough. So, what can we do beyond that? How can setup a solid, safe and sound surge protection system to my house？

The answer is a multi layered or cascaded surge protection. You need to install a surge protection device (SPD) at your electric panel as the first line of defence for strong surges that may encounter. This surge protection device will shunt most of the surge to the ground and only leaving a very limited surge energy to downstream which can be handled by your surge strips or receptacle.
