Extreme weather conditions like hurricanes, tornadoes, blizzards, and thunderstorms pose obvious power-outage threats. Still, other factors contribute to voltage surges more often than you might realize.\u00a0<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Even if a power surge lasts only a fraction of a second, anyone on the receiving end can tell you how dramatic the results can be. Excess electricity can damage technology and electronics, including everything from a computer, TV, or refrigerator to the compressor of an HVAC system. Fortunately, devices to prevent these problems are surprisingly affordable\u2014particularly compared to the cost of replacing damaged items.\u00a0<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">As an engineer and home remodeler, I have worked with electrical contractors to specify and install them.

Its NEMA 4 case is more than we typically see on a budget surge protector device and is durable enough to protect the internal circuitry from rain, snow, and ice.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">The CHSPT2SURGE SPD is Underwriters Laboratories (UL) listed and offers the standard four protection modes. Its LED indicators clearly indicate the status of the unit and its maximum surge protection rating of 36kA.

Like the model we recommend as Best Bang for the Buck, this model has a tough NEMA 4 case that provides all-weather protection, or you can fit it indoors. Because you install this compact SPD outside the breaker box, it can be combined with any manufacturer\u2019s load center.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">With single surge protection of up to 108kA, this is one of the highest-rated Type 2 devices we found. It\u2019s equally suited to residential or commercial use on 120- or 240-volt lines. It offers four modes, useful LED status indicators, and is UL listed for safety.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\" id=\"intermatic-ig-series-surge-protective-device\">Get the Eaton CHSPT2ULTRA whole-house surge protector at <a href=\"https:\/\/www.amazon.com\/dp\/B01AQAKRSS?tag=best-whole-house-surge-protector-20\" rel=\"sponsored nofollow noreferrer noopener\" target=\"_blank\">Amazon<\/a> or <a href=\"https:\/\/homedepot.sjv.io\/c\/2084711\/456723\/8154?u=https%3A%2F%2Fwww.homedepot.com%2Fp%2F204761136&amp;subId1=BV\" rel=\"sponsored nofollow noreferrer noopener\" target=\"_blank\">The Home Depot<\/a>.<\/p>\n<p>\t\t\t\t\tHonorable Mention<\/p>\n<p>\t\t\t\t<a class=\"product-card-link\" href=\"https:\/\/www.amazon.com\/dp\/B003NVLWN2\/?tag=best-whole-house-surge-protector-20\" rel=\"noopener sponsored noreferrer nofollow\" target=\"_blank\"><\/p>\n<p>\t\t\t\t\tPhoto: Amazon\t\t\t\t\t\t\t\t\t<\/p>\n<p>\t\t\t\t<\/a><\/p>\n<p>\t\t\tWhat We Like\t\t<\/p>\n<p>\t\t\t\t\t\t\t\tUses cost-effective modular replacements<br \/>\n\t\t\t\t\t\t\t\t\t\tCan be installed as Type 1 or Type 2<br \/>\n\t\t\t\t\t\t\t\t\t\tHas 6 modes for greater protection<\/p>\n<p>\t\t\tWhat We Don\u2019t Like\t\t<\/p>\n<p>\t\t\t\t\t\t\t\tWeather resistant but not completely waterproof<\/p>\n<p>\t\t\tProduct Specs\t\t<\/p>\n<p>\t\t\t\t\t\t\t\tSPD:\t\t\t\t\t\t\t<\/p>\n<p>\t\t\t\t\t\t\t\tType 1 or Type 2\t\t\t\t\t\t\t<\/p>\n<p>\t\t\t\t\t\t\t\tProtection rating:\t\t\t\t\t\t\t<\/p>\n<p>\t\t\t\t\t\t\t\t50kA\t\t\t\t\t\t\t<\/p>\n<p>\t\t\t\t\t\t\t\tNEMA enclosure:\t\t\t\t\t\t\t<\/p>\n<p>\t\t\t\t\t\t\t\tType 3R\t\t\t\t\t\t\t<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Another versatile option, the Intermatic IG Series can be installed by a professional electrician as a Type 1 device for the main power line or as a Type 2 device alongside the main breaker panel. The robust rainproof plastic case is rated NEMA 3R for use indoors or out (though it\u2019s not fully waterproof). Its 50kA protection rating is provided via six modes for greater protection than the standard four.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Another unique feature of this surge protector for home protection is its use of replaceable modules. Virtually every other whole-house surge protector has to be replaced in its entirety after one or more surge incidents, depending on severity.

The UL-listed surge protector uses Thermally Protected Metal Oxide Varistor (TPMOV) to dramatically reduce the chances of unexpected failure. Installation can be before or after service entrances and utility meter cabinets, but the case is rated for indoor use only.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">While most surge protectors have four modes of protection, the Smart Guard offers six. With 50kA per channel and two channels, the protection rating totals an impressive 100kA, which should be sufficient for just about any surge event. If one of the three independent modules fails from overload, a built-in power switch allows you to isolate the surge protector, making replacement easy and safe.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Get the Intermatic Smart Guard whole-house surge protector at <a href=\"https:\/\/www.amazon.com\/dp\/B00SBC0LTE\/?tag=best-whole-house-surge-protector-20\" rel=\"sponsored nofollow noreferrer noopener\" target=\"_blank\">Amazon<\/a>, <a href=\"https:\/\/lowes.sjv.io\/c\/264145\/897039\/12374?u=https%3A%2F%2Fwww.lowes.com%2Fpd%2FIntermatic-Smart-Guard-Commercial-Residential-Indoor-Whole-House-Surge-Protector%2F5005387799\" target=\"_blank\" rel=\"noreferrer noopener sponsored nofollow\">Lowe\u2019s<\/a>, or <a href=\"https:\/\/www.intermatic.com\/Product\/IG2240-IMSK\" rel=\"sponsored nofollow noreferrer noopener\" target=\"_blank\">Intermatic<\/a>.<\/p>\n<p>How We Chose the Best Whole-House Surge Protectors<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">For those without in-depth electrical knowledge, choosing a surge protection device can be confusing. That\u2019s why I kept the selection criteria as straightforward as possible while still making sure there were options for every homeowner. With the help of the Bob Vila research team, I looked at over two dozen devices to ensure we had a good mix of what\u2019s currently available.\u00a0<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">We considered SPDs with a range of kiloAmps for varying levels of protection. We also took into account that some devices suppress electrical surges better than others, so more advanced models may have a comparatively low kA rating. We also chose a number of National Electrical Manufacturer Association (NEMA) ratings to maximize installation options. Keep reading for more information on kA and NEMA ratings and other important considerations.<\/p>\n<p>What to Consider When Choosing a Whole-House Surge Protector<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Circuit breakers with surge protection\u200b can safeguard your electrical devices and appliances in the event of a power surge. Before you choose an electrical surge protector\u200b, it\u2019s important to understand the various features they have to offer and how they will affect your level of protection. The following guide covers many of the technical and safety considerations to keep in mind while shopping for the best whole-house surge protector.<\/p>\n<p>Types of Surge Protectors\u00a0<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Although commonly called \u201csurge protectors,\u201d technically, these are \u201csurge protection devices.\u201d When considering the best SPD for your home, you will want to consider which category they fall under. Some are designed to shield individual items from the damage caused by power spikes, whereas those we focus on in this article offer whole-house surge protection. There are two distinct forms of the latter, making three types of SPDs in total.<\/p>\n<p>Type 1<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Type 1 devices offer the highest level of protection from external sources and also provide general protection from internal power surges. Low-power spikes might get through, but those are generally nondestructive. These surge protectors are installed where the supply from the utility company meets the main breaker box\u2014what\u2019s termed the \u201cline side.\u201d This means power cannot get into the home without flowing through the SPD, so only safe levels of electricity make it through.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Installing a Type 1 surge protector\u200b requires disconnecting power to your home while work is carried out. A licensed electrician must also complete the installation, which can add considerably to the <a href=\"https:\/\/www.bobvila.com\/articles\/whole-house-surge-protector-cost\/\" target=\"_blank\" rel=\"nofollow noopener\">whole-house surge protector cost<\/a>. In some cases, it\u2019s also necessary to inform the power company before work is carried out.<\/p>\n<p>Type 2<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Perhaps the most popular kind of SPD, Type 2 surge protectors can be installed inside the main breaker panel, also called a load center, or somewhere beside it. Any DIYer can accomplish installation with the requisite electrical experience. That said, if you aren\u2019t completely confident in your abilities, you should at least consult (if not hire) a qualified electrician.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Depending on user configuration, Type 2 SPDs can protect an individual circuit or all the circuits within an electrical panel, plus subsidiary panels downstream of it. Many provide similar levels of protection as Type 1 devices, but it\u2019s important to check the specifications.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Note: The latest code from the National Fire Protection Association proposes all new homes have Type 1 or Type 2 devices installed as standard and that any replacement service panel installed in existing homes includes one.<\/p>\n<p>Type 3<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Generally called \u201cstrip surge protectors\u201d or \u201creceptacle surge protectors,\u201d these are popular, low-cost devices that plug into any household outlet. They typically have four to six additional outlets and are a convenient way to protect low-power devices like TVs, computers, or gaming consoles.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Technically, these gadgets are surge arresters. Unlike Type 1 and Type 2 surge protectors, they don\u2019t absorb excess power but rather transfer it to the ground wire. While they are effective in the majority of cases, it\u2019s not accurate to assume they offer total protection. It\u2019s also important to understand the <a href=\"https:\/\/www.bobvila.com\/articles\/surge-protector-vs-power-strip\/\" target=\"_blank\" rel=\"nofollow noopener\">difference between a surge protector and a power strip<\/a>. Though the two often look similar, even <a href=\"https:\/\/www.bobvila.com\/articles\/best-outdoor-power-strip\/\" target=\"_blank\" rel=\"nofollow noopener\">outdoor power strips<\/a> do not have a surge-protection element.<\/p>\n<p>UL Certification<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">UL, formerly known as Underwriters Laboratories, is an independent organization recognized worldwide for safety testing and certification. The current standard for surge-protection devices is UL 1449 (3rd Edition), and the term \u201cUL listed\u201d is frequently used to describe this. Whole-house electrical surge protection devices should also be listed as a Transient Voltage Surge Suppressor (TVSS) and typically are labeled as such on the device.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">UL 1449 covers numerous aspects of the SPD, including how fast it reacts to a surge, the current required to trip it, and the level of protection offered. A whole-house surge protector must be able to produce results within the specified limits for as many as 15 consecutive tests.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Devices may also be CSA rated. This is a highly regarded global organization, and certification underlines the high safety standards of the device.<\/p>\n<p>Nominal and Maximum Continuous Operating Voltage<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">The nominal voltage in the U.S. (the voltage provided at your household outlets) is 110\/120 volts. In many other countries, it is 220\/240 volts. Whole-house surge protectors are frequently capable of switching to either, but it is worth checking.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">The maximum continuous operating voltage (MCOV) is the amount of voltage a surge protector will allow through without tripping. Having the device trip every time the power hits 121 volts, for example, would cause unnecessary wear, so the MCOV is set a little higher. Generally, this provides a margin of between 15 percent and 20 percent. For example, a 120-volt surge protector with a 20 percent margin would have an MCOV of 144 volts.<\/p>\n<p>Voltage and Surge Protection Ratings<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Manufacturers of electrical panel surge protectors often use terms like \u201chigh voltage protection.\u201d A lightning strike can send 30,000 volts into a household electrical system, so protecting against that kind of power certainly sounds impressive. However, while the voltage protection rating is calculated by UL and CSA in their testing, they are often not prominent within the product details.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">More often, the headline figure is the surge-protection rating. This is the amount of electrical current that can be absorbed, measured in kA, which is thousands of amps. The minimum is usually 10kA (10,000 amps), but it depends on the device type. The best whole-house surge protectors are generally rated from 30kA upward. That\u2019s usually sufficient to deal with the worst storms or power generation problems, though far higher limits are common.<\/p>\n<p>NEMA Enclosure Type<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">NEMA has a standardized rating system covering electrical device enclosures used in the U.S. It specifies the environments where a particular device can be installed and used safely.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">There are two aspects to NEMA ratings: the protection the enclosure offers to the equipment inside against dirt, dust, etc., and the protection the enclosure offers to personnel who might come into contact with it.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Whole-house surge protectors vary considerably regarding NEMA types. NEMA 1 is the lowest rating, stating that an enclosure is for indoor use and provides basic protection against possible electric shocks. At the other end of the scale, a NEMA 4X-rated product is suitable for indoor or outdoor use, including offshore, and offers protection from windblown dirt, sand, rain, and more. Avoid purchasing an SPD that does not have a NEMA rating.\u00a0<\/p>\n<p>Additional Features<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">While a single surge is unlikely to knock out your protection completely, it\u2019s possible that after numerous events, the unit may fail. If the SPD has done its job properly up to that point, you may not even be aware of a problem. Fortunately, even the most basic whole-house surge protection device has an LED display to show that the unit is operational.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">More complex models\u200b may feature additional lights to show a fault condition, while others have audible alarms. For those who use smart technology in the home, some options can integrate with smartphones and home automation systems to send details of a surge event or surge protection status to a smartphone or tablet.<\/p>\n<p>Installation<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">A Type 2 whole-house electric panel surge protector can be installed by anyone with sufficient knowledge of how the main breaker panel functions. The number of breaker spaces required and their amperage can vary. It\u2019s important to understand you are dealing with high voltages, so if you have any doubt or uncertainty about your abilities, it\u2019s smart to talk to or hire a qualified professional electrician regarding surge protection installation\u200b.<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Type 1 whole-house surge protectors are line-side devices, which means they are fitted between the external utility cable and the main breaker panel. Installation of these devices must be carried out by a certified electrical contractor. Not doing so will almost certainly invalidate any home insurance should a fire or fault occur. Additionally, this may be illegal and could result in you being prosecuted by your utility company because line-side cable and equipment belong to them.<\/p>\n<p>The Advantages of Owning a Whole-House Surge Protector<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">Joel Worthington, President of <a href=\"https:\/\/mrelectric.com\/\" rel=\"noreferrer nofollow noopener\" target=\"_blank\">Mr. Electric<\/a>, a <a href=\"https:\/\/www.neighborly.com\/\" rel=\"noreferrer nofollow noopener\" target=\"_blank\">Neighborly<\/a> company, says, \u201cWhole-house surge protectors provide comprehensive coverage for the entire home, such as HVAC systems, large appliances, and hardwired devices, not just sensitive electronics like TVs and computers.\u201d\u00a0<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">For such widespread protection without a high price tag, we think whole-house surge suppressor protector\u200b devices deserve more attention than they get. Installing a whole-house surge protector offers the following benefits:<\/p>\n<p>An SPD offers sensitive electronic devices, major electrical appliances, and HVAC systems surge protection for a relatively low cost. That could result in savings of thousands of dollars, particularly in areas where lightning storms are common.<\/p>\n<p>Around 80 percent of power surges happen within the home. They may be small, but the cumulative effect is that they shorten the life of any device that\u2019s permanently plugged in, even while in standby mode. Whole-house surge protectors prevent that.<\/p>\n<p>For households that rely on well water, these devices can prevent loss of water supply.<\/p>\n<p>A number of home insurance policies do not cover <a href=\"https:\/\/www.bobvila.com\/slideshow\/16-problems-a-power-outage-can-cause-at-home-52947\/\" target=\"_blank\" rel=\"nofollow noopener\">problems caused by power outages<\/a> or damage caused by power surges.<\/p>\n<p>FAQs<\/p>\n<p class=\"wp-block-paragraph article-paragraph skip\">You may still have a few unanswered questions about the use of surge protectors for homes. Some of the more common queries are addressed below. It may also be helpful to review our guide on <a href=\"https:\/\/www.bobvila.com\/articles\/what-not-to-do-in-a-power-outage\/\" target=\"_blank\" rel=\"nofollow noopener\">what not to do in a power outage<\/a>.\u00a0<\/p>\n<p>Q. What is the difference between a power strip and a surge protector? <\/p>\n<p class=\"schema-faq-answer article-paragraph skip\">A <a href=\"https:\/\/www.bobvila.com\/articles\/best-power-strip\/\" target=\"_blank\" rel=\"nofollow noopener\">power strip<\/a> simply provides additional outlets. Surge protectors can look very similar but include devices to prevent power spikes from damaging the equipment and electrical devices plugged into them. True surge protectors will detail the protection provided.\u00a0<\/p>\n<p>  Q. Does a whole-house surge protector need its own breaker? <\/p>\n<p class=\"schema-faq-answer article-paragraph skip\">According to expert electrician Joel Worthington, \u201cA whole home surge protector will generally need its own breaker. The breaker connects the surge protector to the home\u2019s electrical system and allows it to divert excess voltage from power surges away from the circuits.\u201d<\/p>\n<p>  Q. Where should you mount a whole-house surge protector? <\/p>\n<p class=\"schema-faq-answer article-paragraph skip\">A whole-house power surge protector\u200b is generally mounted inside or near the main electrical panel so that it can be easily connected to the panel.\u00a0<\/p>\n<p>  Q. If a surge comes from appliances like AC units and larger appliances, do I still have device protection before the breaker panel? <\/p>\n<p class=\"schema-faq-answer article-paragraph skip\">The best whole-house surge protector will prevent external power fluctuations from damaging equipment inside the home. They can also prevent feedback from internal surges traveling through the <a href=\"https:\/\/www.bobvila.com\/articles\/best-circuit-breaker\/\" target=\"_blank\" rel=\"nofollow noopener\">circuit breaker<\/a> system. However, a best-case scenario is to protect sensitive electronics with a strip surge protector as well.<\/p>\n<p>  Q. Do whole-home surge protectors work against lightning? <\/p>\n<p class=\"schema-faq-answer article-paragraph skip\">Yes. The recommended minimum protection from a whole-house system is 40,000A, though many are much higher. A lightning strike is usually around 30,000A. That said, it\u2019s always advisable to unplug what you can if a lightning storm is imminent.<\/p>\n<p>  Q. How long does a whole-house surge protector last? <\/p>\n<p class=\"schema-faq-answer article-paragraph skip\">It\u2019s impossible to say because component wear depends on the frequency and severity of power surges. Many manufacturers claim a life expectancy of 5 years or more, although 10 years is not uncommon. However, some low-cost devices may need to be replaced after just one significant lightning storm.
