Get a Whole House Surge Protector Before It’s Too Late!

Lightning surgeGot your electronics fried from a power surge? Or maybe you want some protection after hearing about your neighbor’s unfortunate power surge accident.

There are a lot of different options that you can use to safeguard your house and electronics from these transient power surges.

In this article, you’re going to learn the basics so you can easily make an informed decision on what solution you really need for your home.

What’s a Surge Protector?

A surge protector is basically a device that will protect your electrical equipment from a sudden burst of energy known as a power surge.

Take note that a lightning strike is not the biggest danger to your electronics. The fact is that 80% of power surges are generated inside your home and this is mainly caused by power hungry, motor driven appliances such as air conditioners, refrigerators, etc.

It’s a rare situation where a single huge spike will destroy your equipment. There are small surges that happen on a regular basis and these surges will eventually add up and degrade the performance of your electronics. Your local power company can also introduce these harmful power surges and that’s why it’s also important to use surge protection in your electrical service panel.

Also there’s no existing surge protection for a direct lightning strike. You have to look into lightning rods if you’re really worried about that.

Types of Surge Protection

This website primarily focuses on whole house surge protectors but take note that it’s not a complete solution when you want total protection from damaging electrical surges.

It would definitely help improve your situation and it does make you feel a lot safer but it’s not a complete and enough solution. What you want to try and achieve is a layered and cascading approach. You have your first level of protection at the power meter then the second level is going to be at your breaker panel. Lastly, the third level of suppression is at the point where you plug your electronic devices.

Let’s discuss the 3 most popular and practical types of surge protection.

Type 1

They are also known as secondary surge arresters and they’re typically installed on the line side of the main service entrance. This is between your utility pole and where the electricity enters your service panel. You can think of them as your first line of defense when it comes to voltage spikes as they protect from nearby lightning strikes and transient surges from your power company.

Type 2

A whole house surge protector is categorized as a type-2 SPD and is known as service or branch surge panel. They’re installed on the load side of the main service entrance and they also provide protection from nearby lightning strikes and other internally generated power surges from motor driven appliances.

Type 3

This category provides point of use surge protection and it’s more commonly known as power strips. They suppress the lower level voltage spikes that can be damaging to more sensitive electronics like your computer, audio component, televisions and other household appliances.

Take note that power strips should indicate that they have surge protection capabilities in order to really protect you from voltage spikes.

Type 4

This is also known as surge protection modules and they give a different kind of point of use protection than your power strips. This type of surge protection is more ideal for industrial use

A popular approach that many people do is layer their surge protection. They will install a whole house surge protector (type 2) and they will also use power strips to provide point of use protection as their last line of protection for their more sensitive electronics.

Important Criteria When Choosing Whole House Surge Protectors

Compliant with UL 1449 – Make sure that the whole house surge protector is fully compliant with the Underwriters Laboratories, UL 1449 3rd edition. The UL 1449 is a safety and performance standards of surge protection equipment by the Underwriters Laboratories and it was revised to its 3rd edition back in 2009. Basically, the changes were about the compliance with the international standards and the change in testing procedures to better recreate practical and real-life situations. In short, consumers are the biggest winners with this revision.

Protection Modes – Learn what modes of protection your surge protection provides. An ideal device should at least have 3 modes of protection and they are Line to Neutral, Line to Ground and Neutral to Ground on both of the lines.

Maximum Surge Capacity – This one is measured in kiloAmps and this basically tells you how much of a surge the device can survive.

Short Circuit Current Rating – This will tell you the highest level of short circuit current that surge suppressor can ward off.

Maximum Continuous Operating Voltage – This is probably the most important criteria when checking out a whole house surge protector and basically what you want to look out for is a higher number.

Warranty – Make sure that you carefully read the warranty information for a device. There a lot of technicalities that these companies will throw on you so it’s best to read the fine print.
