How We Chose the Best Whole-House Surge Protectors
For those without in - depth electric noesis , choosing a surge trade protection gadget can be confusing . That ’s why I kept the survival of the fittest criteria as straightforward as potential while still making sure there were options for every homeowner . With the assist of the Bob Vila inquiry team , I look at over two dozen devices to ensure we had a good mix of what ’s presently available .
We consider SPDs with a reach of kiloAmps for varying levels of protection . We also took into account that some devices inhibit electric surges better than others , so more advanced models may have a relatively low kA rating . We also chose a telephone number of National Electrical Manufacturer Association ( NEMA ) rating to maximize installation options . Keep say for more info on kA and NEMA ratings and other important retainer .
What to Consider When Choosing a Whole-House Surge Protector

Some are designed to shield single items from the damage due to power spikes , whereas those we focus on in this article provide whole - house surge protection . There are two trenchant forms of the latter , urinate three case of SPDs in total .
Type 1 equipment pop the question the highest level of protection from external sources and also leave general tribute from intragroup power surge . gloomy - major power spikes might get through , but those are generally nondestructive . These upsurge protectors are installed where the supply from the utility companionship cope with the main ledgeman corner — what ’s term the “ job side . ” This means superpower can not get into the home without flowing through the SPD , so only good levels of electricity make it through .
Installing a Type 1 twist requires disconnecting power to your home while body of work is carry out . A licensed linesman must also fill in the installation , which can bring substantially to awhole - firm surge guardian ’s cost .

Perhaps the most democratic kind of SPD , Type 2 upsurge protectors can be installed inside the chief surf venire , also call a payload center , or somewhere beside it . Any DIYer can reach induction with the requisite electrical experience . That said , if you are n’t completely confident in your abilities , you should at least consult ( if not engage ) a qualified electrician .
look on drug user configuration , character 2 SPDs can protect an single lap or all the circuit within an electric instrument panel , plus subsidiary company panel downstream of it .

Generally called “ flight strip upsurge shielder ” or “ receptacle surge guardian , ” these are popular , low - cost devices that stop up into any family release . They typically have four to six additional outlets and are a commodious way to protect scurvy - top executive equipment like TVs , information processing system , or gaming consoles .
Technically , these contrivance are surge arresters . Unlike Type 1 and character 2 surge shielder , they do n’t absorb excess baron but rather transfer it to the primer coat conducting wire . While they are effective in the majority of typesetter’s case , it ’s not accurate to put on they offer full trade protection . It ’s also crucial to understand thedifference between a spate protector and a power comic strip . Though the two often look similar , evenoutdoor power stripsdo not have a upsurge - auspices element .
UL Certification
UL , formerly lie with as Underwriters Laboratories , is an sovereign organization tell apart worldwide for safe examination and certification . The current standard for spate - protective cover devices is UL 1449 ( 3rd Edition ) , and the term “ UL number ” is oftentimes used to depict this . Whole - menage electric surge auspices devices should also be listed as a Transient Voltage Surge Suppressor ( TVSS ) and typically are label as such on the gadget .
UL 1449 covers numerous aspects of the SPD , admit how tight it respond to a billow , the current required to trip it , and the level of protection provide .

Nominal and Maximum Continuous Operating Voltage
The nominal potential difference in the U.S. ( the electromotive force provide at your household mercantile establishment ) is 110/120 volt . In many other country , it is 220/240 volt . Whole - house surge protectors are oft subject of switching to either , but it is worth checking .
The maximal uninterrupted operating voltage ( MCOV ) is the amount of voltage a surge protector will earmark through without tripping . have the gadget trip every time the power strike 121 volt , for instance , would get unnecessary wear , so the MCOV is set a little gamy . broadly , this provide a allowance of between 15 percent and 20 percent . For example , a 120 - volt billow protector with a 20 per centum margin would have an MCOV of 144 V .
Voltage and Surge Protection Ratings
Manufacturers of whole - house surge protector often use term like “ high-pitched voltage tribute . ” A lightning strike can send 30,000 volts into a menage electric system , so protect against that kind of power surely sound telling . However , while the potential drop protection rating is depend by UL and CSA in their examination , they are often not striking within the product inside information .
More often , the headline figure is the surge - auspices 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 adenylic acid ) , but it look on the gadget character . The best whole - house upsurge guardian are broadly rated from 30kA upwards . That ’s normally sufficient to deal with the worst storms or superpower generation problems , though far higher limit are common .
NEMA Enclosure Type
NEMA has a standardised rating system of rules breed electrical gadget envelopment used in the U.S. It specifies the environments where a particular gadget can be installed and used safely .
There are two aspect to NEMA rating : the protection the enclosure offers to the equipment at bottom against dirt , junk , etc . , and the protection the enclosure put up to personnel who might derive into striking with it .
Whole - house surge shielder vary considerably regarding NEMA types . NEMA 1 is the lowest rating , express that an inclosure is for indoor use and provides introductory protection against potential electric shocks . At the other end of the scale , a NEMA 4X - give away product is suitable for indoor or out-of-door exercise , including offshore , and offers protective covering from windblown dirt , sand , pelting , and more . Avoid purchasing an SPD that does not have a NEMA evaluation .
