Unless they are produced intentionally, power surges can not be predicted, which is what makes them so dangerous. A power surge is an unexpected, sudden spike in electrical voltage that exceeds the normal expected flow in a building’s circuit. Wall outlets in U.S. homes supply an average of 120 volts of power. Power surges can vary in magnitude, supplying anywhere from thousands to tens of thousands of volts of power. They have the potential to cause immediate damage to electronic devices and appliances, while others can gradually degrade the internal components, reducing their lifespan and efficiency over time.

Another characteristic of power surges that makes them so dangerous is their sources--they can be caused by many things. Power surges can come from both external and internal sources. Lightning strikes are one of the most well-known external causes, and they are capable of producing high-voltage surges that travel through power lines and into your home’s electrical system. Other outside sources, such as utility grid switching, power grid failure, and power line damage, which can be caused by falling trees or accidents, can also result in surges. Inside a property, power surges can happen when large appliances, like air conditioning units and refrigerators, turn on and off. This momentarily uses a larger-than-expected amount of power that disrupts the system’s stable voltage flow. Other inside sources of power surges can include overloaded circuits, malfunctioning appliances, bad wiring, and an increased power demand on the property's electrical system.

A whole-house surge protector is a device that your electrician will install directly onto your home’s electrical panel. It acts as a defender against surges by regulating the voltage that is allowed to enter your property. The surge protector works by detecting voltage spikes and redirecting excess electricity safely to the ground, which prevents it from entering and damaging the home’s electrical circuits and connected devices. This system not only protects against large external surges but also smaller internal fluctuations that can cumulatively cause harm over time.
