The bottom line is that no, surge protectors will not protect against a lightning strike. Lightning is too powerful for even the best surge protectors to handle. Unfortunately, this is the way it is.
What voltage do surge protectors work with?
They are often designed with lower VPRs of 330 or 400.
What happens when you put a surge protector on your home?
When your whole-home surge protector lets through smaller surges, that voltage courses through your home’s wiring trying to reach (and kill) sensitive electronics. But if you’ve installed a point-of-use surge protector, these devices will absorb that extra voltage before it ever reaches your electronics.
What does 700V mean on a surge protector?
If your whole-home surge protector has a high VPR of, say, 700V that means it will let 700-volt surges into your home’s wiring. But 700V is plenty high enough to destroy certain electronic appliances and can potentially cause electrical fires.
What is a whole house surge protector?
You see, whole-home surge protectors are like bouncers. They monitor the amount of electricity entering your home and turn away any “overflow” voltage that might cause harm.
How high is a surge protector?
Whole-home surge protectors typically have VPRs as high as 1,000V. But, remember, high VPRs aren’t necessarily a good thing. In fact, when it comes to stronger protection, the lower the VPR, the better.
How to protect sensitive electronics?
Protect your sensitive electronics by connecting them to point-of-use surge protectors. These “lower level” surge protectors will instantly absorb any excess voltage that gets past your whole-home surge protector.
Can surge protectors overheat?
In fact, some point-of-use surge protectors will overheat if they get just 127V more than what they’re designed to handle.
How often does a surge protector happen?
Perhaps you thought that it happens every once in a while, maybe when there’s a lightning storm. Furthermore for an average home, a power surge actually happens about 20 times a day.

What causes surges in electricity?
Far more common, if not as dramatic, are surges caused by downed power lines, sudden changes in electricity use by a nearby factory, or even the cycling on and off of laser printers, electric dryers, air conditioners, refrigerators, and other energy-sucking devices in the home.
How long does it take to wire a whole house surge suppressor?
Typically, whole-house suppressors are hard-wired to the service panel, a process that takes a licensed electrician about two hours. Whole-house systems should be rated to stop a 40,000-amp surge, at minimum. Features to look for include thermal fuses, and lights or alarms that indicate when a device has taken a hit.
What is a whole house surge protector?
Homeowners can choose from varying types of whole-house surge protectors, also called point-of-service protectors or lightning suppressors, says Carey Mossop, chairman of the National Electrical Manufacturers Association’s Low Voltage Surge Protective Devices Section.
Why do Donovan and Mossop discourage surge protection?
While stores sell DIY surge protection kits, both Donovan and Mossop discourage their use because of the inherent danger of electricity.
Where is Tim Donovan?
Tim Donovan, owner of Donovan Electric in Denver, N.C., often witnesses the aftermath of electrical storms, including damaged electronics, appliances and fires. He says wooded lots or homes near water are most susceptible to lightning strikes and power surges. Even if lightning doesn’t hit directly, he adds, electricity can course through tree roots or water and jump to nearby electric, cable and phone lines, giving it entrance into the home.
What is NEMA rating?
The National Electrical Manufacturers Association (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.
What type of device is best for protection from external surges?
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 non-destructive.
What are the threats of power outages?
Although extreme weather conditions like hurricanes, tornadoes, blizzards, and even just thunderstorms or high wind pose obvious power-outage threats, power surges and spikes unprompted by weather happen more often than you might realize—and can be caused by a variety of things.
What is a whole house surge protector?
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 breaker system. However, a best-case scenario is to protect sensitive electronics with a strip surge protector as well.
How many modes of protection does a surge protector have?
Whereas most surge protectors offer four modes of protection (the way the surge is channeled away from the home’s electric devices), the HEPD80 offers six. While this feature is perhaps only of interest to professional electricians, it can increase the margin of safety provided.
