Bob Vila Radio: Fend Off the Power Surge Scourge

A spike in electricity can fry your electronics. Protect your beloved gadgets and gizmos with a surge protector. Here's how to choose one.

These days, we’re increasingly sharing our homes with electronic devices. Many of them are pretty pricey, and that includes computers, home theater setups, and sophisticated AC or heating systems. One characteristic most of those devices share is that they have circuit boards that can be easily damaged by power spikes.

The best way to avoid such calamities? Surge protection. Here are some tips on how to choose: Look for protectors that have a “joules rating” of 700 or higher. Joules ratings tell you how much power the protector can absorb before it fails. You’ll also want a protector that has a “clamping voltage rating” of 400 volts or less. Clamping voltage describes how much voltage the unit needs to sense before it begins absorbing energy.

You’ll also want to have a look at the warranty. Many companies reimburse for devices that get fried while plugged into their protectors. Check the fine print. Another option—whole-house surge protectors. Many types are available, and they’re not all that expensive.
