Whole House Surge Protector
The modern home is filled with sensitive and expensive electronics, from your big-screen TV and computers to your smart appliances. All of these devices contain delicate microprocessors that are highly susceptible to damage from voltage spikes, also known as power surges. A whole house surge protector, professionally installed by the electricians at Gragg Electrical Services, is the best way to defend all of your valuable electronics. This single device provides a powerful shield for your entire home, offering protection that is far superior to individual plug-in power strips. It is a crucial investment in protecting your modern lifestyle.
A whole house surge protective device (SPD) is installed directly at your main electrical panel. It works by constantly monitoring the incoming voltage from the utility company. If it detects a voltage that is significantly higher than normal, which indicates a power surge, the device instantly diverts the excess and harmful electrical energy safely away from your home’s wiring and sends it to the grounding system. This process happens in a fraction of a second, clamping down on the voltage spike before it can travel through your circuits and destroy your sensitive electronics. It acts as a gatekeeper, protecting everything downstream.
Power surges can come from a variety of sources. The most dramatic and powerful surges are caused by lightning strikes, even ones that occur miles away from your home. A lightning strike can induce a massive voltage spike onto the utility lines that then travels directly to your house. Other common sources of surges are external to your home, such as fluctuations from the power grid when the utility company switches circuits or when power is restored after an outage. Surges can also be generated from inside your own home when large appliances with motors, like your air conditioner or refrigerator, cycle on and off. A whole house surge protector defends against all these types of surges.
While many people use plug-in surge protector power strips for their computers and TVs, these devices offer only a limited, secondary layer of protection. They are not designed to handle the massive energy of a large, external power surge, such as one from a lightning strike. A powerful surge can easily overwhelm a simple power strip, destroying it and the devices plugged into it. The best practice, recommended by the Insurance Institute for Business & Home Safety, is a layered approach. A whole house surge protector at the panel provides the primary defense against large surges, and point-of-use power strips can then provide a second layer of defense for your most sensitive electronics.
The installation of a whole house surge protector must be performed by a licensed electrician. It involves working inside your main electrical panel, which is dangerous for anyone without the proper training. Our electrician will install a new double-pole circuit breaker in your panel and will connect the surge protective device to this breaker and to the neutral and ground bus bars. The wires connecting the SPD must be kept as short and straight as possible for it to be effective, which is a detail a professional understands. We will install a high-quality device from a reputable manufacturer that has a high surge current capacity rating, measured in kiloamps (kA).
A properly installed whole house surge protector is a smart and affordable investment when you consider the total value of all the electronic equipment in your home. The cost of replacing a modern refrigerator’s control board, a high-end television, a computer, and multiple other small electronics after a power surge can easily run into thousands of dollars. The cost of a professionally installed whole house SPD is a small fraction of that potential loss. It provides constant, silent protection for every single outlet in your home, 24 hours a day.
Do not leave your valuable electronics unprotected. The question is not if a damaging power surge will occur, but when. With the increasing number of sensitive electronics in our homes, the need for robust surge protection has never been greater. Contact Gragg Electrical Services to have a licensed electrician assess your panel and install a high-quality whole house surge protector. It is the most effective way to safeguard your investment in today’s technology and provide you with lasting peace of mind.
absolutely wonderful experience. very helpful, explanatory and went above and beyond to get us up and running again!
You will never find a more polite, respectful person than Cory Boosz. We had massive problems that we never could have fixed and within a short amount of time everything was done! We will never go to anyone else for any electrical problems. We also appreciate the fact that after we called late on a Friday he still came to our house that day, thanks again for everything Cory!
I've been very happy with Gragg. So far I've used them for 2 projects and anticipate more. The staff is knowledgeable, thorough, and courteous.
Mike was great. He answered all my questions, explained everything that he was doing, and cleaned everything up when he was done
Working with Mike was an absolute gold‑standard experience. His professionalism, deep education in his field, and commitment to safety were evident from the moment he arrived. He came prepared with creative solutions, fair pricing, and a level of thoroughness that ensured every party understood the codes, the safety considerations, and the work being performed. Mike doesn’t just fix a problem — he teaches, protects, and earns your trust in the process. He treats your home with the same care he’d give his own, even bringing his own shoe covers without being asked. That level of respect and attention to detail gave our family real peace of mind. We knew we were safe, we weren’t being overcharged, and we weren’t being sold anything unnecessary. His expertise, execution, and integrity are unmatched. Because of the experience we had with Mike, I will be a loyal customer for life. I can’t speak highly enough of him, his skill set, or the way he conducts his work. I recommend him wholeheartedly to anyone who wants a true professional who delivers excellence every single time.
Gragg Electric is the best! They saved our Memorial Day Weekend! Corey was the best! Highly recommend this company!
Amazing service! Gragg managed to fit us in on a busy holiday weekend Friday. Corey was fantastic—he diagnosed and fixed the problem in no time at all.
Mike was phenomenal. Highly recommend this company. Great pricing and very prompt. I would give it 10 stars if I could .
Corey came after hours and handled business and he was phenomenal- didn't upsell me - just solved my problem and got me power again. Can't thank him enough
Came in and fixed our problem in less than 20 minutes. VERY THANKFULLY FOR COREY!!
Update….Used Gragg again on 5/15/26. Still same great service. They are our go to for electrical work always! Professional. Arrived timely. Explained issues. Nice guys. Reasonable price. We will call them in future for electrical work. Recommend them to anyone looking for an electrician.
I was selling my house and the buyers home inspection listed a few electrical items that they wanted to repair with our close date coming up I reached out to Gragg electrical they came out same day to give an estimate and did all the work a few days later. They were polite cleaned up and worked and acted very professional. Next the city inspector came out and said they did a good job but he wanted a couple things changed Gragg came back and met the inspector at the house they told me prior to the inspector arriving they would do anything they need to do to make everything right however they wanted to talk to the inspector because they didn’t agree with his list well they when over everything with the inspector and in the end Gragg Electrical was right and no repairs were needed. Very happy with the work and the crew and they would be the first place I would call if I need a electrician again
BRO! Gragg electrical services, and this guy here is awesome!!! If I ever have an electrical issue again I know who I'm calling. I thought he was going to be here after hours so I was prepared for the after hours dispatch fee. He got here before after hours so the dispatch fee was greatly reduced. I believe it only did take him maybe 15-20 minutes and he figured out the problem got her fixed. I don't think I've ever done a review for a company. But if it helps y'all and it helps him I'm down. Thank you so much again Mike. My daughter has power in her room again. I salute you dude.
Corey was dead spot on! You're lucky to have him for an employee! I will use Craig electric for all my electrical needs from now on!
Fast, friendly service at a very reasonable price. Highly recommend their services
I needed an electrician to replace some loose outlet slots on my mom‘s Louisville, Ohio house. I’m listing it for sale after her passing, unfortunately. Gragg electric, from the woman who answers the phone and schedules the appointment to the actual electrician, Michael, were all very helpful, professional and personable. Michael was very communicative and would text me arrival times and actually showed up on that time and even before. He was very accommodating, even doing this job before he actually “clocked on” for work. He brought his own shoe/boot covers and was respectful of me and of my mom‘s home. He even labeled Mom‘s main breaker box which, for some reason was not previously labeled. I would definitely recommend Gragg and Mike Thank you for making this stressful time a little less so
Excellent service! Mike was very professional, called appropriately ahead of time to make sure someone was home. He was upfront about all estimates needed, providing good information the whole time. He answered my questions appropriately and made me feel at ease about my electrical work. Overall, would recommend!
Had them come out for a new home purchase box inspection. My mother in law was home and she said the gentleman was very polite. I had talked to the lady in the office twice and she was very helpful and was able to save me some money! I would recommend this company for sure!
My technician was very informative, was great at breaking down what was going on, explaining how and why. Very very great experience 10/10 would recommend highly.
Mike was great! He called when he was in route, showed up on time and completed the work in a very timely fashion. I felt the cost was reasonable too!
The gentleman (Mike) very professional person, he also explained in detail what had to be done, he sat up everything that had to be done financing and everything. Put us on the schedule as quick as possible. A professional company. Thanks Mike for all you have done for us. Barb Stamps and John T Stamps. I highly recommend this company to anyone.
Mike carefully inspected my house and thoroughly explained the repairs I need. I would highly recommend this company.
Mike was absolutely wonderful to work with. He took time to explain the process to me and made sure I understood everything which actually ended up being very simple. I would HIGHLY recommend Gragg Electric because of Mike.
We would highly recommend this Company. Besides doing excellent work, they treated us extremely well. We felt as if everyone that works there had our best interest in mind.
I setup an appointment online over the weekend for a service call and received a phone call first thing Monday morning. They were able to have a technician out that morning. Mike W. came out and reviewed our problem with a breaker and was able to diagnose some of the issues that caused it. He also explained everything that was found and why it could cause a problem. Very professional and I thought the cost was reasonable.
Excellent service. We had a few outlets in our kitchen go out and lights were flickering. Mike came out so fast and not only got them working but also checked the whole house to make sure everything was working. He was very thorough and made sure we knew what was going on.
Mike did an excellent job diagnosing the issue and solved the problem despite adverse weather conditions. He was courteous and polite and very respectful.
Mike was very cordial, clear in his explanations of the work/estimate that would have to be done and the options that I have. I look forward to having them fix my electrical needs.
Great local company in East Canton. Very knowledgeable and skilled crews. I would highly recommend for your next electrical job!
The technician who came out was thorough and very pleasant. He determined what the issue was with malfunctioning landscape lighting and provided a reasonable quote for repair. Parts needed to be ordered and I’m expecting the same outstanding service when replacement parts are installed.
This was my first time using this company. Response time was great. There was no charge for coming and making an estimate for the work. The electrician was friendly and explained everything. I think this is a great company. Rates were reasonable and I am very pleased with their work.
I could not be happier with my experience, prompt, efficient, clean and diagnosed the problem quickly. I would highly recommend Gragg Electrc
Gragg Electric workmanship is top-notch. Their service and expertise are unmatched, but most importantly, especially in today's economy, they are HONEST and fair priced. I highly recommend them for any electrical work that you may need.
Great experience! Mike was very knowledgeable.Helped me understand all the details of my project without being pushy with sales! Definitely recommend him!
I called Gragg Electrical Services, LLC to come out regarding my dryer outlet not getting enough power. They were able to get me on the schedule the next day at no additional charge! Cory Boosz came out timely and found the issue. He kindly explained what was going on and some potential solutions. Cory did a great job fixing the problem and didn’t even have to turn the power off so I could continue working. He also cleaned up after he was finished. Thank you Cory and Gragg for providing us with kindness and relief during a difficult time. I will definitely be using this company again.
We just finished a detached garage build and needed the whole structure wired from the subpanel to the outlets and lighting. The electrician from Gragg was efficient, clearly experienced with this type of work, and the finished product looks exactly like what I had pictured. Everything is properly grounded, the circuits are sensibly distributed, and it passed the electrical inspection without a single correction. For a project I was a little nervous about managing it went about as smoothly as possible.
The lights in my living room had been flickering intermittently for months and two different electricians had looked at it without finding the cause. Gragg Electrical spent the time to actually trace the issue back to a loose neutral connection at the panel that had been creating voltage fluctuations throughout the circuit. Problem solved on the first real diagnosis. Sometimes you just need someone who is willing to look harder and these guys did exactly that.
Our kitchen renovation required running new circuits for a double oven and an island with dedicated outlet circuits and Gragg Electrical coordinated seamlessly with the rest of our contractors. The rough in work was done on schedule, the inspector had zero notes, and the finish work after drywall was clean and precise. My contractor told me they were the easiest sub on the whole job and that kind of professionalism ripples through an entire project.
We had an issue where we lost power due to the neutral wire breaking on the side of the house. I called Gragg Electric and they were able to send someone out within a few hours. We ended up needing to have not only the wire replaced, but the meter box and additional grounding installed to bring it up to current code. Everyone at Gragg Electric was very kind and professional and worked quickly to get our power restored. I would highly recommend them.
Corey was awesome. He did the job quickly and efficiently. He also answered all my questions.
Cory was so nice, respectful and knowledgeable. He had my problem solved within 15 minutes! I would definitely recommend Gragg in the future and will be working with them again to wire my She-shed!! So excited. A+++++
We had a very large tree fall between the power pole and the house tearing the wires from the house. Gragg is one of the nicest companies I've worked with. Mike W. was our Electrician for the hurry up job. He is professional and helpful, not to mention that he is very nice. I'm glad I picked Gragg Electrical Services and I will happily recommend them!
He was professional and very knowledgeable about the electrical work done.I would highly recommend.
They are quick, professional, and nice to work with. I would definitely recommend them and plan to work with them again.
Great service and people Mike was a pleasure to talk to and work with great company.
Urgent issue. Arrived on time and resolved the issue quickly and ensured everything was safe thank you
We had a recurring problem with loss of power to part of our house that was all on the same circuit. We had a subscription with another company, but when we called they couldn’t get us an appointment for several weeks. We called Gragg and they came out in 3 days. We had a technician name Cory, who was very knowledgeable and diagnosed and fixed the problem very quickly. He explained the problem in terms I could understand. He was competent and friendly to boot. You could tell he loved his job too.
Family can now live in safety because of the awesome people at Gragg Electrical Services. We had 3 outlets with the loosest recepticles you've ever seen. None of our cell phone chargers would stay plugged in... Great electricians and a blessing to our family. Came over to the west side of Massillon for no extra travel fee. Awesome, affordable, and family-oriented.
Called in and spoke with Brittany about needing an estimate, she was so kind and thorough. Cory came out to provide the estimate and was incredibly nice and professional. He took the time to explain everything clearly and answer my questions. I really appreciated his honesty and how easy he was to talk to. Great experience overall!
Very satisfied with quality of service and work will use Gragg for any further electrical work.
Service was quick and complete. I will definitely use them again for my electrical needs.
Excellent, friendly service. Fair price. Mike W. Did a great job!! Thank you
Mike was our technician and he did an outstanding job. He showed up on time, was diligent and solve our problem. I would highly recommend.
Cory was very professional when he arrived. He was respectful of our home and explained the new safety requirements that are now included in their work. I feel very confident working with Gragg.
Mike did an awesome job on our estimate! Was extremely thorough and helped me understand the whole process!
Cory was very knowledgeable and friendly about answering questions, I don’t know the ins and outs about home electricity. We went through the inspection in detail and gave an easy to understand explanation about what is needed. I recommend these folks to anyone looking for a home electrician.
The website is amazing and user friendly! Customer service was outstanding and courteous. Corey was very informative, knowledgeable, polite and prompt. I will be calling Gragg for future electrical work and referring others.
Dr. Frankenstein could take some notes from Kyle and Cam at Gragg Electric, who did an amazing job resurrecting our ancient generator from the dead. Kyle’s customer service was phenomenal. Brittany (hopefully that’s how it’s spelled; my apologies if it’s “Britneigh”) who scheduled the appointment was incredibly friendly and helpful. Cost was reasonable and what I would expect from the service rendered. I would definitely recommend Gragg Electric to others, and I will be having them back for my next electric project!
Great employee that came to our house. The gentleman told us exactly what we needed and why. Answered any questions we had. Great experience!
Mike and his team were able to finish a panel install and completed multiple fixes. Will definitely recommend to others.
Fantastic service! Highly recommend Gragg Electric. Affordable and reliable! Thanks for providing the necessary upgrades we needed.
Andrew and Harley put in an overhead light in my grandma’s living room. They were thorough, double checked and gave us options when something unexpected popped up, and were very kind to my grandma. Highly recommend for their timeliness, excellent communication and friendliness.
Solid choice for local electrical work. Highly recommend if you are in need of a quality electrician. Handles both residential and commercial.
We had quit a few things that needed done at the house the crew that came out was very respectful! Explained everything they were doing, answered all questions we had, and did an amazing job at everything that needed done . I Will definitely recommend this company to everyone I know.
This company is amazing and actually cared that I wasn't able to come home until work was done and rushed to get me scheduled. Truly the best company around. Out of 14 that I called I'm confident I received the best price and service. HIGHLY RECOMMENDED!!!!!!

Most Common Whole House Surge Protector Questions
Protecting your home’s electronics from power surges is a smart move. Homeowners often have questions about how whole house surge protectors work and why they are necessary. Here are the answers to the most common questions on this topic.
The difference between a whole house surge protector and a simple plug-in power strip is significant in terms of both location and capability. A whole house surge protector, also known as a Service Entrance or Type 1 or Type 2 Surge Protective Device (SPD), is a robust device that is installed by an electrician directly at your main electrical panel. Its job is to be the first line of defense, protecting your entire home from large, external power surges that originate from outside, such as those from lightning strikes or utility grid switching. It diverts the vast majority of the surge’s energy safely to ground before it can even enter your home’s circuits.
A surge protector power strip is a point-of-use or Type 3 SPD. It is a much smaller device that is designed to protect only the specific electronics that are plugged directly into it. It provides a secondary, weaker layer of protection. While these strips are useful for cleaning up any small amounts of surge energy that might get past the main protector, they are not designed to handle a large external surge on their own. A powerful surge from a nearby lightning strike will easily overwhelm and destroy a simple power strip, and it will likely take the connected TV and computer with it.
The best practice recommended by electrical safety experts is to use a layered approach. The whole house surge protector at the panel does the heavy lifting, stopping the big, dangerous surges from entering the house. The point-of-use surge strips then provide a final cleanup for any residual energy and can protect against smaller surges that might be generated from inside your home. A whole house unit protects everything, including your hardwired appliances like your oven and dishwasher, which cannot be plugged into a power strip.
Power surges can originate from both outside and inside your home. The most powerful and destructive surges are external ones. Lightning is the most well-known cause. A direct lightning strike to your home or a nearby utility line can send millions of volts of electricity through your wiring, which is catastrophic. Even a lightning strike a mile away can induce a very strong and damaging surge onto the power grid that then travels to your house. Another common external source is the utility company itself. The switching of power grids, faults in transformers, or the restoration of power after a blackout can all create significant voltage spikes that travel down the line to all the homes on the grid.
However, a surprising number of power surges are actually generated from within your own home. These are smaller, more frequent surges that can degrade and damage your electronics over time. These internal surges are created by large appliances with powerful motors. Every time your central air conditioner, your refrigerator, or even your garage door opener cycles on, its motor creates a small electrical disturbance and voltage spike on your home’s wiring. While these individual surges are not as dramatic as a lightning strike, their cumulative effect over many years can lead to the premature failure of sensitive electronic components in your other devices.
A whole house surge protector installed at your panel is effective at stopping the large external surges. It can also help to clamp down on the larger internal surges generated by major appliances, protecting the rest of the circuits in your home. This comprehensive protection is something that simple power strips cannot provide.
The installation of a whole house surge protector is a job that must be performed by a licensed electrician, as it involves working inside your main electrical panel. The device itself is a small box, typically mounted on the side of or just below your main panel. The electrician will first turn off the main breaker to safely de-energize the panel. They will then install a new double-pole circuit breaker, usually a 15-amp or 20-amp breaker, into an available space in the panel. This new breaker will serve as the connection point and a disconnect for the surge protector.
The electrician will then connect the wires from the surge protector to the new breaker, the neutral bus bar, and the ground bus bar inside the panel. It is a critical rule of installation that these wires be kept as short and as straight as possible. The length and path of these wires directly impact how effectively the device can react to a surge. Long, looping wires increase the impedance and can slow down the device’s ability to divert the surge energy to ground. A professional electrician understands the importance of this detail and will ensure the installation is optimized for the best performance.
Once the device is wired in, the electrician will restore power and check the indicator lights on the surge protector to ensure it is powered on and functioning correctly. Most whole house SPDs have a set of LED lights that show their status. If these lights ever go out, it means the device has sacrificed itself to stop a major surge and needs to be replaced. The entire installation process is typically very quick, often taking less than an hour for an experienced electrician.
This is a common question with a nuanced answer. A whole house surge protector provides excellent protection against the common surges that are induced onto power lines by a nearby lightning strike. These are by far the most frequent type of lightning-related damage. However, no surge protection device, no matter how robust, can be expected to protect your home’s electronics from a direct lightning strike. A direct strike contains an unimaginable amount of energy, millions of volts and hundreds of thousands of amps, which is powerful enough to vaporize wiring and cause explosive damage.
For protection against a direct lightning strike, you would need a completely different type of system called a lightning protection system or a lightning rod system. This involves installing large copper or aluminum air terminals (lightning rods) on the roof of your house, which are connected by heavy-duty cables to a series of grounding electrodes buried deep in the earth. This system is designed to intercept a direct strike and provide a safe path for the massive current to travel directly to the ground, bypassing your home’s structure and wiring entirely.
So, it is important to have realistic expectations. A whole house surge protector is your best defense against the common, everyday surges and the surges from nearby lightning. A lightning protection system is what you need for the much rarer, but catastrophic, event of a direct strike. For most homeowners, a professionally installed whole house surge protector offers a very high level of practical and affordable protection against the most likely electrical threats.
The cost of having a whole house surge protector professionally installed is a very reasonable investment, especially when compared to the potential cost of replacing multiple damaged appliances and electronics. The total cost of the project includes both the price of the surge protective device (SPD) itself and the labor cost for the electrician to install it. The devices themselves can range in price based on their brand and their surge current capacity rating, which is measured in kiloamps (kA). A higher kA rating means the device can handle a larger surge, and these devices typically cost a bit more.
The installation labor is usually very straightforward for a qualified electrician and can often be completed in under an hour. The electrician will need to install a new breaker in your panel and make the necessary connections. The total cost for a professional installation, including a high-quality device, is typically in the range of a few hundred dollars. This is a very small price to pay for the peace of mind and the protection it provides for the thousands of dollars worth of electronics in your home.
When you get a quote from Gragg Electrical Services, we will recommend a high-quality SPD with a robust kA rating that is appropriate for a residential application. Our upfront price will include both the device and the complete, professional installation. It is one of the most cost-effective electrical safety and protection upgrades you can make to your modern home.
Yes, for the best possible protection, it is still recommended that you use high-quality, point-of-use surge protector power strips for your most sensitive and expensive electronics, even after you have had a whole house surge protector installed. This strategy is known as “cascaded” or “layered” protection. The two devices work together as a team to provide the most comprehensive defense against power surges. The whole house unit at the panel is the first line of defense, handling the big, external surges. The power strip at the outlet is the second line of defense.
No whole house surge protector is 100% perfect; a tiny amount of “let-through” voltage from a very large surge can sometimes still get past it. The point-of-use surge strip is there to “clean up” this small, residual surge energy before it reaches your delicate computer or home theater system. The power strip can also help to protect against smaller surges that might be generated from inside your home on the same circuit, which the main panel protector might not see.
Think of it like the security at an important building. The whole house protector is like the main security gate at the entrance to the property, stopping the big threats from getting in. The surge protector power strip is like the security guard standing right outside the door to the most important room, providing a final check and an extra layer of defense. By using both, you can be confident that your most valuable electronics have the best possible protection from all types of electrical surges.
A whole house surge protector does not have a set lifespan in terms of years, as its life is determined by the number and intensity of the power surges it is exposed to. The protective components inside the device, which are typically Metal Oxide Varistors (MOVs), work by absorbing and diverting the excess energy from a surge. Each time they do this, they degrade just a little bit. After absorbing one very large surge, or many smaller surges over time, these components will eventually wear out and will no longer be able to provide protection.
Most whole house surge protectors have a set of LED indicator lights on the unit that show its status. As long as these lights are on, the device is working and providing protection. If one of the lights goes out, it is a signal that the device has sacrificed itself to protect your home from a significant surge and that it needs to be replaced. It is a good idea to check these indicator lights periodically, perhaps once or twice a year, to make sure your protection is still active.
Many high-quality surge protectors also come with a manufacturer’s warranty that often covers a certain amount of connected equipment damage. This shows the manufacturer’s confidence in their product’s ability to protect your home. While the device itself may need to be replaced after a major surge event, the cost of replacing the surge protector is minuscule compared to the cost of replacing all the electronics it saved.
No, a whole house surge protector does not protect against brownouts or sags in voltage. The function of a surge protector is very specific: it is designed to protect against over-voltage conditions (surges and spikes), where the voltage rises significantly above the normal level. A brownout is the opposite condition; it is an under-voltage event where the voltage drops significantly below the normal level for a sustained period. This can cause lights to dim and can also be damaging to some motors and electronic power supplies.
A surge protector is not designed to do anything during a brownout. It will simply allow the lower voltage to pass through to your devices. The type of device that protects against brownouts and power outages is called an Uninterruptible Power Supply (UPS). A UPS contains a battery, and when it detects low voltage or a complete loss of power, it instantly switches over to its battery backup to provide clean, stable power to the connected devices.
A UPS is typically used for very sensitive and critical electronics, like a desktop computer or a home network server. It gives you time to save your work and shut the equipment down gracefully during a power outage. For comprehensive protection, you might use a whole house surge protector to defend against surges, and a smaller, point-of-use UPS for your computer to defend against brownouts and blackouts. The two devices serve different but complementary protective functions.
