How can I protect my electronic­s from surges?

- PAUL F. P. POGUE

Every day, power surges wipe out TVs, video games, phones, appliances and other electronic devices and they’ve become more of a concern thanks to our increased use of electronic­s. Low-power devices with sensitive circuit boards, such as tablets or smartphone­s, are more vulnerable to a power surge than larger devices such as appliances.

A power surge is a short burst of electricit­y that can range anywhere from hundreds to hundreds of thousands of volts. A sufficient­ly powerful surge can damage or destroy electrical equipment.

A variety of things can cause a power surge, including downed power lines and lightning strikes. Sometimes, variances from utility companies can produce surges as electricit­y is delivered.

Any metal entering your home can carry an electrical current — like electrical wires, telephone or cable wires, and metal pipes. So, it’s impossible to completely stop a power surge. The circuit breakers in your electrical panel offer a small amount of protection, but it’s not particular­ly robust. Your best bet is a surge protector, which diverts the power surge away from your home and into nearby ground.

You can block surges at various points in the process. The least expensive and easiest is a power strip, which includes a circuit breaker that flips in the event of an excessive surge. These strips offer a level of protection that is better than nothing, but you can’t rely on them solely to protect against power spikes. You’ll get a better defence via installing a wholehouse surge protector at your electrical panel. Many electricia­ns call this a must for keeping your home safe. This job will cost between $300 and $500 and should be performed by a licensed electricia­n. This monitors electrical spikes and dissipates them safely into the ground.

Pros say surge protectors add life to things you never even thought about by stopping minor surges you probably rarely noticed. Light bulbs tend to last longer with such protection, for instance.

If you have multiple electrical panels, such as a separate one for your pool, each panel requires protection.
