From flat-screen televisions to computers, treadmills and even answering machines, our homes are loaded with electronic equipment that could be damaged by a power surge – a momentary rise in the flow of electricity. In normal household wiring, the standard voltage is 120 volts. When the voltage rises above this level, this is considered a power surge.
The most familiar source of a power surge is probably lightning, though it is actually one of the least common causes. A more common cause is the operation of devices that require lots of power, such as air conditioners and refrigerators. When these items switch on and off, they upset the steady flow of electricity, causing a slight surge. These small surges can gradually damage electronic equipment and shorten their lifespan and efficiency.
The electronic devices that are common in our homes today contain many delicate components that are vulnerable to power surges. Microprocessors, which are an integral part of all computers as well as many home appliances, are particularly sensitive to surges.
To help protect your electronic equipment, we suggest investing in one or both of the following types of surge protection:
