Surge Protection for Your Home: Whole-House vs Point-of-Use

Today’s homes have state-of-the-art technology and smart devices that require electricity to run. Unexpected power surges can damage these devices and lead to significant repair and replacement costs. By investing in a whole-house surge protector, you can help protect appliances, electronics, and electrical equipment from damaging transient overvoltage.

How Does Whole-House Surge Protection Compare to Point-of-Use Surge Protection?

A whole-house surge protector is set up at or near the electrical service or panel. In comparison, a point-of-use surge protector is designed to protect specific plugged-in electronics. While whole-house surge protection is more comprehensive, the best option is to create a layered approach using point-of-use and whole-house methods.

Key Takeaways

• Whole-house surge protection provides broad protection at or near the home’s electrical service or panel, while point-of-use devices provide additional protection for specific connected electronics.
• Surge protection can reduce the risk of costly damage to sensitive electronics, appliances, HVAC systems, and other connected electrical equipment.
• A layered approach is typically the best method. It relies on a blend of whole-house and point-of-use systems.
• Type 1 and Type 2 surge protection devices (SPDs) are whole-house protectors. Type 3 SPDs are point-of-use devices.
• Because surge protectors can wear out after repeated overvoltage events, it’s important to check the status or indicator light to verify that the unit is still working properly.

Why Surge Protection Matters

Power surges can happen for a variety of reasons. Anytime there is a major storm or a problem with the grid, power levels can spike. Large appliances cycling on can also cause brief voltage fluctuations, while other surge sources include nearby lightning, utility switching, grid events, and electrical faults. 

When these power surges occur, they can impact the safety of your family. Transient overvoltage can damage sensitive electronic components in appliances, HVAC equipment, computers, entertainment systems, and other connected devices. A significant surge may cause immediate equipment failure, while repeated smaller events can contribute to component degradation over time. Besides increasing the risk of fires, this can also lead to future wiring repairs and rewiring.

Lightning strikes, utility or grid issues, and electrical events within the home can all lead to power surges. In Central Oregon, utility switching and power restoration associated with outages can also produce electrical disturbances. Because there are many potential sources involved, adopting a layered approach to home surge protection is one of the best ways to protect your home’s electrical systems.

What Is Point-of-Use Surge Protection?

While a whole-house surge protector is intended to protect your entire home, point-of-use surge protection targets one specific area. These devices are designed to limit transient overvoltage reaching connected equipment by diverting surge current or otherwise limiting the voltage, depending on the device design.

Often, you’ll hear terms like surge protective device (SPD) used when talking about surge protection. An SPD is designed to protect your connected equipment by redirecting or limiting transient overvoltage.

Examples

You can get a variety of different point-of-use surge protection for your home. Power strips and outlet-based protectors are the most popular options. You can also get plug-in adapters that can be used for a single item, such as a smartphone or tablet.

It’s important to note that basic power strips aren’t automatically surge protectors. You must verify that the device is specifically rated for surge protection before using it.

Pros

Older homes in Bend’s historic neighborhoods may have electrical panels and wiring that should be evaluated when homeowners are considering whole-house surge protection. By adopting home surge protection, homeowners can enjoy a number of important benefits.

• Affordable: Point-of-use surge protection is much cheaper than whole-house systems because they only need to be installed in specific areas.
• Easy to Install: Whether you use a plug-in adapter, outlet-based protector, or power strip, these units are fast and easy to set up. Unlike a whole-home system, you don’t need to hire an electrician to plug in a power strip.
• Device-Specific Protection: If you have a computer, television, gaming system, or other compatible plug-in electronic device that you want to protect from surges, point-of-use protection can provide an additional layer of protection.

Cons

When it comes to surge protection for a home, it’s also important to consider some of the downsides associated with point-of-use systems. The biggest drawback is that they only provide limited coverage. They protect plugged-in devices, but other devices can still be damaged by unexpected power surges.

What Is Whole-House Surge Protection?

A whole-house SPD provides broad protection at or near the home’s electrical service or panel. These units are extremely effective at stopping power surges, although they tend to come with a higher upfront cost.

How It Works: Installed at the Electrical Panel

With an electrical panel surge protector, our electricians will install the surge protector into your electrical panel. If everything is working properly, the surge protector just waits and monitors the electrical flow. When a surge occurs, the SPD limits the transient overvoltage by diverting or limiting surge current. Once the electrical surge dissipates, the surge protector stops conducting electricity, and the electrical panel resumes its normal functioning.

Pros

By investing in whole-house protection, you can enjoy a few key benefits.

• Whole-House Coverage: One of the most significant benefits of a whole-house system is that it is set up to cover all of the devices and electronics linked to your circuit breaker panel. However, because a whole-house surge protector can’t stop every power fluctuation, having point-of-use and layered protection is essential.
• Appliance and HVAC Protection: Many of your appliances and HVAC equipment are expensive to replace. By preventing damage, you can save money in the long run.
• EV Chargers: Whole-house surge protection can help protect expensive permanently connected electrical equipment, including compatible EV charging equipment, from transient overvoltage.

Cons 

While there are some advantages to whole-home systems, there are downsides to consider as well. Unlike a power strip, these systems need to be installed by a professional. They also cost more upfront, even though they often save money over time.

Whole-House vs. Point-of-Use: Which Is Right for You?

If you’re uncertain about which system works best for your family’s needs, we can help. Our electricians can evaluate your existing setup and discuss the best options for your needs. In most cases, the best option is to use whole-home and point-of-use protection. These systems complement each other, so installing whole-house surge protection together with appropriate point-of-use equipment can provide more comprehensive, layered protection. Then, point-of-use systems can be used to provide added protection for your sensitive electronics.

For a better understanding of which system is right for your needs, consider the pros and cons of whole-house surge protection vs. point-of-use surge protection.

The Difference Between Type 1, 2, and 3 Surge Protectors

As part of your layered surge protection, you can incorporate Type 1, Type 2, and Type 3 SPDs. 

• Type 1: A Type 1 SPD is a permanently connected device that can be installed on the line/service side of the service equipment overcurrent device or in other configurations permitted for Type 1 applications. It can provide whole-house protection against transient overvoltage, including surges associated with utility events and lightning.
• Type 2: Typically, a Type 2 surge protector is installed on the load side and connected to a dedicated breaker or on service equipment. This setup provides broad surge protection for electrical equipment downstream of the SPD. It is also considered a type of whole-house surge protector.
• Type 3: A Type 3 surge protector is considered point-of-use surge protection. It is intended to be a final layer of protection for sensitive or valuable electronics and appliances.

Cost of Installing Surge Protection

The average cost for whole-house surge protection can vary based on the SPD type, electrical panel configuration, equipment selection, installation requirements, and any additional electrical work. However, the upfront cost of these systems is often balanced out by your long-term savings. If one or more of your appliances are damaged in a power surge, the repair costs quickly add up to more than the cost of surge protector installation in Bend, OR.

Frequently Asked Questions

Is whole-house surge protection worth it?

A whole-house surge protector installation is generally worth it because it protects expensive appliances and electronics. If just your refrigerator is damaged, a replacement can easily cost much more than the average cost for a surge protector installation.

Do I still need surge protector strips with whole-house surge protection?

Yes. As long as your strips are designed and rated for surge protection, you should continue using them as an extra layer of protection.

How long does a whole-house surge protector last?

It really depends on the system and the usage. In many cases, these systems can last for 5 to 10 years. High-quality units can last up to 20 years. 

How do I know if my surge protector is still working?

Your surge protector is still working if its indicator light is on. If it is dim, blinking, or off, the protection has likely worn out. However, each surge protector is designed differently, so you should check with the manufacturer to find out which lightning indicator means it is working properly. SPDs can wear out following significant or repeated events, which is why it’s important to check the indicator lights and surge protector status regularly.

Does a whole-house surge protector protect against lightning?

A whole-house surge protector won’t make your home immune to lightning strikes. It can help against the transient overvoltage caused by indirect lightning strikes nearby but is not effective against direct strikes. For better protection, you should consider a layered approach and lightning protection.

Where is a whole-house surge protector installed?

It is installed inside or adjacent to your electrical service or panel. The exact location depends on the SPD type, electrical system, equipment, and installation configuration. A qualified electrician can determine the appropriate location for the specific application.

What should homeowners look for in an SPD?

When choosing an SPD, consider whether the device type is appropriate for its intended application, its manufacturer specifications, electrical-system compatibility, installation requirements, and protection-status indicators. For whole-home protection, a qualified electrician can evaluate the home’s electrical service and panel configuration and recommend equipment designed for the specific installation.
