I use Ditek residential surge protectors, one on the main disconnect below my meter base and a second one on my electrical panel inside my home. I rely on the Ditek DTK-120/240HD2 Home Surge Protector, capable of 100,000A of surge current capacity and diagnostic LEDs to indicate power and surge protection status. It is a parallel connected AC surge protector and is available in a standard external enclosure or a flush mount enclosure. These surge protectors include a ten year warranty.
