8 Best Whole House Surge Protector 2022 [Top Picks & Buying Guide]

The need for whole house surge protection has been felt by all who have a major investment in their electronics and appliances. A power surge can cause a lot of damage to your electronics and there is no way to know that it has happened until you use an electronic for the first time.

A whole-house surge protection device works very differently from a simple power strip. The power strip is only capable of protecting one device from surges but a whole house surge protection device can protect your entire home from power surges.

However, when selecting a surge protector, you need to make sure that it is the right fit for your needs. Some people may have a big house, while some might have a small apartment. You need to take size into consideration when you are looking at different options.

When you have a large home, you should go with a whole-home surge protector. These protectors can be used in areas that may have a circuit overload problem.

In this review, I will look at 8 different types of whole house surge protectors and give our opinion about which ones are the best to use. I will also look at some of the features you need to consider when selecting a surge protector and how it will benefit your home.

Whole House Surge Protector Buying Guide

There are a few things to consider when choosing which whole house surge protector is suitable for your home. These features include:

Diagnostic LEDs:

These lights are very useful because they tell you if the surge protector is plugged in and working. If it doesn’t have any lights, there is no way to know if it is protecting your home or not.

Having a diagnostic light or indicator light can give you peace of mind. You can always be safe knowing that your protection is working.

Do you want to buy a whole house surge protector? Exploring specific criteria may help you in this case.

Here are three crucial factors in buying a whole-house surge protector – 

Surge Current Limit

The maximum rating for power surge on all SPDs shows how much current they can withstand in the event of a power surge. 60,000 amps per phase are the maximum high-end models can tackle, whereas entry-level units can only manage roughly 40000 amps per phase.

Manufacturer hypes surround surge protectors. Ignore the jargon and go straight to the specs.

Kiloamps are the unit of measurement for SPDs (1kA = 1,000 amps). The SPDs that are the cheapest start at around 10kA. They can only withstand one massive surge before being destroyed, making them a poor investment.

Instead, search for the SPD having at least a 50kA rating. It will outlast a gadget with a 10kA rating.

Type of Surge Protector

There are several surge protectors types available in the market. They are:

  • Type 1 SPD
  • Type 2 SPD
  • Type 3 SPD
Whole House Surge Protector

They all have different technologies for surge protection, making them suited for varied applications. You can find a lot of variations for type 2.

Modes of Protection

Many modes can be found in a single SPD because multiple modes provide greater performance in more versatile ways. This may include features such as 4/6 protection modes. Others may have more than 6. They are always great options.

You can also look for an SPD with alarms or an indicator installed to give you warnings. So that when a power surge happens, you will know it.

Find the best SPDs here. But exercise caution about the electrocution hazard!

There are always live wires and disconnecting the electricity does not turn them off. If you do not know anything about it, contact a professional. Conducting this without experience may come as hazardous.

Frequently Asked Questions

How Long Does A Whole House Surge Protector Last?

There is no definite answer to this. The life of a surge protector depends on how much power it has to stop as well as the quality of the parts used.

Does A Whole House Surge Protector Work Even If The Power Is Out?

Yes, they work even when the power is off.  This is because they monitor the power and not the lights. That’s why surge protectors should always be installed high up and not near any plug outlets.

How Often Should I Replace My Surge Protector?

You probably don’t need to replace your surge protector unless it is getting old and not working as well anymore.

If you still think that its time to get a new one, you should check the quality of your old surge protector.  For example, if it is melted or has any exposed wires then you should replace it with a new one.

Do These Companies Honor The Warranties?

Yes, they do. You can e-mail them or call customer service to ask about your warranty if it is still valid.

If A Surge Comes From Appliances Like AC Units And Larger Appliances, Do I Still Have Device Protection Before The Breaker Panel?

Yes, you do. Surge protectors are not limited to the power coming from your electrical panel. They work with all the appliances that are plugged in throughout the house.

You should still have surge protectors for appliances though.  For example, you can place one on your AC unit or your oven. This ensures that the appliances will not burn out when a surge comes through the grid.

What’re Features Do Type 1, 2, And 3 Whole House Surge Protectors Have?

Type 1 whole house surge protectors have just a single point of protection that goes directly to the electrical panel.

Type 2 whole house surge protectors have a single point of protection and an additional line that sends the power back to the electrical panel through outdoor equipment like your meter.

Type 3 surge protectors have a single point of protection, another for household appliances, and one sent to the electrical panel.

If you are doing the installation yourself, the cost depends on how many things you need to install.  For example, if you want to install a wall plate and it is done by wiring then this will cost more than installing a simple outlet.

If you want to install additional devices like GFCI or AFCI, this will also cost additional.
