Whole House Surge Protector Installation – Things to Know

Installing a whole-house surge protector is not very complicated. It should come with instructions so you can install it yourself without needing to hire an electrician.

There are some things you need to know about installing a whole-house surge protector:

  • It should be installed high up on the wall where it is easily accessible.
  • Make sure that you read the instructions on how to install it before you do so. You need to first disconnect your power before you start the installation.
  • For some models, you will need a special outlet box which can be purchased at home improvement stores. You might even need more of these than one depending on how many outlets you need to install.
  • You should never touch or try to plug in your surge protector while the power is on because this could be dangerous.  This also goes for grounding cables as well.

Buying Guide

1) Energy Absorption

The energy absorption rating of a surge protector is expressed in joules; a higher value indicates a higher quality device. Imagine it as a wall that prevents any additional force from entering. If the number is larger, the surge protector can take more forceful hits from a single or series of occurrences before failing.

Thus, a surge protector rated at 500 joules may, in theory, withstand ten strikes of 50 joules, four strikes of 125 joules, two strikes of 250 joules, and a single strike of 500 joules. Devices having a joule rating of less than a thousand are safe to use, including lamps, radios, and battery chargers. Surge protectors with a joule rating of 2500 or higher are highly recommended for electronic devices such as computers and home entertainment systems.

If you don’t want to risk your pricey mixer to an unexpected power surge, suppressors that protect against 1,000 joules are appropriate for modest gadgets that you might use in the kitchen or other home areas.

Protecting office equipment like copiers and printers with a surge suppressor rated at 1,000 to 2,000 joules is also a good idea in the garage or workshop, where power tools will be utilized.

Your most valuable electronics, including laptops, home theater systems, gaming consoles, and more, should be protected by a surge suppressor with a joule rating of 2,000 or more.

2) Clamping Voltage

This value indicates the voltage at which the MOVs begin to conduct electricity to the ground line.  Better safety is indicated by a lower clamping voltage. The UL rating provides three different degrees of safety: 330 V, 400 V, and 500 V. Clamping voltages above 400 V are typically unsafe.

A lower clamping voltage is preferable. As the value drops, the surge protector’s ability to withstand high voltage spikes decreases. Therefore, a surge protector with a clamping voltage of 330 V (the best option) is preferable to one with a clamping voltage of 500 V (a less desirable option) because the latter will allow a larger surge or spike to occur (potentially damaging components) before taking action.

3) Response Time

The response time of a surge protector is how quickly it will react to divert excess voltage. This time is typically measured in nanoseconds. Electronics may give the impression that they work instantaneously, but in reality, their operation takes some time.

The response time and the clamping voltage are closely related to one another. The rapid activation of surge protectors with lower response times allows them to reroute excess voltage before it has the opportunity to cause damage to the protected device. Choose those with response speeds of one millisecond or less if you want the very best (or less).

There is a very tiny lag between the onset of the power surge and the activation of surge protectors; the protection they provide is not instantaneous. A slower response indicates that your electronic devices will be subjected to the surge for a more extended period of time. You should look for a surge protector with a response time of one millisecond or less.

4) UL 1449

Every Surge Protective Device must comply with UL 1449, the industry-recognized safety standard (SPD). Manufacturers of surge protectors must adhere to the standards outlined in this document, which detail the certification criteria, design requirements, and product performance testing that must be performed before the product can be sold to the general public.

So if this information isn’t clearly labeled on the packaging, the surge protector in question probably won’t do an excellent job shielding your electronics from power surges.

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 it’s 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.

How Much Does It Cost To Install?

If you are hiring an electrician, the costs depend on where you live.  For example, in some areas, they can charge up to $100 per hour.  There are some electricians who charge by the job instead of an hourly rate though.

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.

What Is A Ground Fault And How Does It Relate To Whole House Surge Protectors?

If the device has a ground fault, it means that there is an imbalance in the current. This does not mean that your house surge protector is not working. It just means that there is a problem with the wiring to your home or an appliance somewhere along the line.

What Is The Size Of A Whole House Surge Protection Device?

The size of a surge protector depends on its voltage.  It also needs to match the breaker in your electrical panel.

Warping Up

Surge protectors are a good investment for your home because they keep you from having to replace appliances that have been damaged by surges. They also have the ability to block any surge coming through the grid and into your house, which is something that can’t be said about other types of protection devices.

This article has given you all the information you need in order to make an informed decision on whether or not this type of purchase is right for you. You can choose any of the best whole surge protectors from the above list. They are the most reviewed and best surge protector of this year.

I hope it’s helped answer any questions and help guide you toward making a smart choice!
