Lightning can strike when residents are away and thus unable to unplug their electrical devices and appliances. A plug-in, point-of-use electrical surge protector diverts power surges to a ground connection. Using surge protectors allows a residents to drastically limit the voltage that reaches their plugged-in devices.

To protect a home from electrical surges, homeowners can have a licensed electrician install a surge protector at the service entrance. This type of surge protector is usually placed between the electrical meter outside the home and the main electrical service panel or breaker box of the house.

A whole-house system can prevent a power surge from entering the house's internal wiring system, thus protecting all electrical devices inside the house.
