A surge-gap device (300) includes two electrodes (310, 315), having an inside portion and an outside portion, and an insulator material (320), which secures the two electrodes (310, 315). The insulator material (320) has an opening through the material to expose an open-air gap (325) that is defined by the space between the two inside portions of the electrodes (310, 315). In cases of a voltage surge, the surge-gap device permits an arc to pass between the proximate inside portions of the electrodes (310, 315) across the open-air gap (325), which gives a current surge a low impedance path to ground. Also included is a fastener (305) for electrically coupling the surge-gap device (300) to a ground plane (220) of an external electrical device (300) for suppressing the voltage and current surges.
