How does a power surge cause damage?

In most homes, electricity comes in the form of an alternating, single-phase current of 120 V, 60 Hz. When an overvoltage occurs, the voltage exceeds the ceiling of 169 V.

A voltage surge can damage your appliances and electronic devices. If the voltage exceeds the normal operating level of a device, it can cause an internal electric arc. The resulting heat can damage the circuits and other electronic components of the device.

Less strong, but recurring, surges can also gradually damage your electronic equipment. After several small power surges, your computer or stereo can continue to operate. And, it happens until the integrity of its components usage is for good. This is when your television, cordless telephone or answering machine mysteriously gives up the ghost.

It protects motors, lights, outlets, switches and other “hard-wired” devices that are not plugged into an outlet or device at the point of use.
