Hey, have you ever thought about all the myths that surround surge protection? I mean, it’s kind of crazy how many misconceptions people have about something as important as protecting our electronics. Let’s dive into some of these and set the record straight.
First off, people believe that surge protectors last forever. Newsflash, they don’t. Many have a lifespan of around 3-5 years, depending on usage and exposure to power surges. I remember reading a report from Consumer Electronics Association which mentioned that around 20% of surge protectors are no longer effective after a couple of significant surges. Imagine relying on a 10-year-old surge protector; that’s like trusting a rusty old helmet to protect your head.
Another biggie is the idea that only lightning causes surges. In fact, a whopping 80% of surges come from sources within your home, such as the operation of high-power electrical devices like air conditioners and refrigerators. According to the National Electrical Manufacturers Association, these internal surges can be just as damaging over time as a single lightning strike. When your fridge or AC cycles on and off, those mini-surges wear down the microprocessors in your electronics gradually. Not cool, right?
Then there’s this notion that all surge protectors are the same. Nope, not even close. Different models offer varying degrees of protection based on their joule rating—a measure of how much energy they can absorb before failing. A run-of-the-mill surge protector might have a joule rating of 200-400. But for more sensitive equipment, you might need one rated at 1000 joules or more. According to an in-depth review on Wirecutter, investing an extra $15-$20 on a higher-rated surge protector can save hundreds or even thousands of dollars in potential damage. Just think about that for a second.
I can’t leave out the classic “A power strip is the same as a surge protector” myth. Let’s squash this one right now. A power strip might give you multiple outlets, but it offers zero protection against power spikes. An actual surge protector, on the other hand, comes with components like Metal Oxide Varistors (MOVs) or Transient Voltage Suppression (TVS) diodes that absorb and divert excess energy. Seriously, why would you spend $1000 on a new flat-screen TV and then hook it up to a $5 power strip?
Oh, and here’s one that always gets me: People think surge protectors work forever without any need for inspection or replacement. Kind of goes back to my first point, doesn’t it? A survey by the Electric Power Research Institute revealed that as many as 1 in 5 homes in the U.S. may have surge protection that’s no longer effective. Next time you clean out your battery drawer or check the smoke detectors, spare a thought for that potentially worn-out surge protector.
This one will blow your mind: Some folks think their insurance will cover damage from power surges so a surge protector isn’t needed. According to an article by Forbes, while some homeowners insurance policies might cover some forms of electrical damage, many won’t cover the cost to replace electronics specifically damaged by a power surge. And even if they do, the deductible might make the claim hardly worth it. Spending $50 on a good surge protector suddenly seems like a brilliant idea, right?
Have you ever heard someone say that small surges can’t do any harm? While a single small surge may not immediately fry your electronics, cumulatively they reduce the lifespan of your devices. The IEEE suggests that continuous exposure to even minor power surges can weaken the internal circuitry of electronic devices over time. Every mini-surge chips away a little more at your gadget’s longevity. It’s like death by a thousand cuts.
Another misconception is thinking that unplugging devices during a storm is the ultimate safeguard against surges. Sure, it helps, but it’s not exactly practical. Are you going to unplug your refrigerator, microwave, and every other appliance every time a storm rolls through? Not to mention the random surges that can occur when you’re not even home. Using a high-quality surge protector ensures continuous protection without having to hustle and unplug all your appliances every time a storm is forecasted.
You might’ve also encountered the myth that point-of-use surge protectors are enough. While they’re definitely important, whole-house surge protection systems offer an additional—and crucial—layer of security. These systems are installed at your electrical panel and act as the first line of defense against both internal and external surges. According to the Institute of Electrical and Electronics Engineers (IEEE), layering point-of-use protectors with whole-house systems can significantly improve the overall effectiveness of your surge protection strategy. Combined protection can reduce the risk of surge damage to virtually all of your home’s wiring and electronics.
Last but definitely not least, how about the belief that surge protectors save energy? Unfortunately, no. While surge protectors play a critical role in protecting your devices, they don’t save energy. Their main function is to manage voltage peaks, not to optimize energy consumption. If energy efficiency’s your goal, you should look into other energy-saving devices and practices.
