Abstract: A surge protector system is provided including multiple surge protector circuits situated within a service panel of a structure. The surge protector circuits are connected between outlets of the structure and one of the surge protection devices of a power distribution network for filtering electric transients before they can reach the various outlets of the structure. This is accomplished by splitting up incoming current and voltage surges on bus bars within the service panel and directing such surges to ground.
