Is a whole-house surge protector worth it?

For most Santa Clara County homes, a service-type surge protective device (SPD) at the main panel is a cost-effective layer that reduces damage from utility transients and many surge events; it works best as part of a layered strategy with plug-in protection for sensitive electronics. It does not replace proper grounding or insurance, but it can extend the life of appliances and reduce costly equipment failures.
