Surge Protection

Why invest in surge protectors?


Simply put, surge protectors will protect your home and your appliances in the event that a power surge should happen. And, believe it or not, power surges happen more often than we think. In fact, lightning is the least common cause for power surges.

Internal power surges

More than half of household power surges are internal. These happen dozens of times of day, usually when devices with motors start up or shut off, diverting electricity to and from other appliances. Refrigerators and air conditioners are the biggest culprits, but smaller devices like hair dryers and power tools can also cause problems.

External power surges

An external power surge, stemming from outside your home, is most commonly caused by a tree limb touching a power line, lightning striking utility equipment or a small animal getting into a transformer. Surges can also occur when the power comes back on after an outage, and can even come into your home through telephone and cable TV lines.

Why worry about power surges?

Your home is filled with items susceptible to power surges. Anything containing a microprocessor is especially vulnerable - the tiny digital components are so sensitive that even a 10-volt fluctuation can disrupt proper functioning.

Microprocessors are found in hundreds of consumer items, including TVs, cordless phones, computers, microwaves, and even seemingly "low-tech" large appliances like dishwashers, washing machines and refrigerators.

Large power surges, as with a lightning strike, can cause instantaneous damage, "frying" circuits and melting plastic and metal parts. Fortunately, these types of power surges are rare.

Low-level power surges won't melt parts or blow fuses, but they can cause "electronic rust," gradually degrading internal circuitry until it ultimately fails.

Small surges won't leave any outward evidence, so you may not even be aware they're happening - even though they may occur dozens or even hundreds of times each day.

Why to choose a whole house surge protector?

People commonly use surge protector strips to protect their computers and television equipment. However the majority of modern appliances have circuit boards, like the one found in television equipment and computer, which can just as easily be damage by power surges. Also LED lighting incorporates miniature circuit board which can be damaged by power surges.
