What Causes Power Surges and How Can I Protect Myself?

When you hear the phrase “power surge”, most of us instantly think of storm clouds sending lightning bolts down toward our home. Or perhaps you think of power lines being zapped by millions of volts coming down from the heavens. Believe it or not, lightning is one of the least causes of power surges, even though its damage can be massive.

What is more likely to cause power surge damage inside our homes, is the use of devices that use a lot of power. Appliances such as air conditioners and refrigerators, for example, can cause our home’s power to fluctuate. Faulty wiring, that does not do its job of monitoring power, can cause this and other threats by allowing too much power to travel through our home’s electrical system.

Last blog we discussed what a surge protector is and the types available in stores. To better understand Surge Protector Ratings here is what they mean.

Clamping Voltage – typically 330V, 400V and 500V – this is the amount of volts that will pass through before directed to the ground. Lower is better.

Energy absorption/dissipation – 200/400/600 joules – states how many energy the surge protector can absorb before it fails. Higher is better.

Response time – how quickly will it work – look for less than one nanosecond.
