While many people think that they’re only the result of lightning storms or blackouts, power surges and spikes can happen for a variety of reasons. For example, there could be a downed power line. Or, faulty wiring or electrical equipment could be the cause. Even a high-powered device like an air conditioner or refrigerator could cause a surge or spike.
While we’re on the topic, what’s the difference between a power surge and a power spike? Ultimately, it’s just the amount of time that the power is operating above normal voltage. In the long run, though, they’re essentially the same thing.
As a homeowner, it’s important to use surge protectors to protect the valuable electronics in your home. Standalone units work well but need to be replaced every couple of years since their effectiveness is reduced with each activation. It’s also good to install whole home power surge protection, but this is typically best done (or even required to be done) by a licensed electrician.
