Identification
-
A surge protector is a device equipped with a circuit breaker that can absorb the shock of a power surge. The surge trips the breaker and prevents the power from reaching the device and doing damage.
Function
-
According to New Mexico State University, a standard 120-volt outlet such as the ones in the U.S. offers power that can fluctuate between 110 and 117 volts. A surge protector is needed when power surges above 120 volts. Electrical devices are sensitive to shifts in current, so a surge protector prolongs the life of equipment.

Warning
-
Dominion DX Group recommends getting a surge protector with an indicator light to show that it is working. The surge trapping device inside wears out with repeated power spikes. After it fails, heating can occur in the protector and a fire can result. Only use surge protectors that have an internal circuit breaker to prevent overload or shorting.
Modems
-
Computer Hope suggests getting a surge protector with a modem line in it as well. Surges can also damage your dial-up modem if the line has no protection.
Considerations
-
Buy surge protectors that offer enough protection for the devices you are plugging in to them. If you are plugging devices that total 1,000 watts into a surge protector that is only rated for 800 watts, then you are not properly protecting your device.
