Lightning and surge protection devices (SPD) work by routing voltage surges and spikes away from the electrical components they are protecting and dispersing it to a ground plane, such as the earth or a copper pipe inside of a building. Every grounding system therefore consists of two main components: the protection device that routes the damaging signals and the ground connection the signals are routed to. It is important that both components are in place and properly utilized. One without the other, or one properly implemented with the other improperly implemented, is the same as no surge protection system at all.
We recommend installing a whole house surge protection device from a brand like Siemens. Installing is usually 1-2 hours depending on the conditions of your existing electrical panel and will provide years of protection from a power surge.
