A surge suppression circuit for a load control device allows the load control device to pass hipot testing, while providing improved protection of the load control device during surge events. The load control device comprises a load control circuit and a filter circuit for preventing noise generated by the load control circuit from being provided to an AC power source. The surge suppression circuit comprises a clamping device adapted to be electrically coupled across the AC power source, and first and second spark gaps coupled across the filter circuit for limiting the magnitude of the voltage generated by inductive components of the filter circuit. The filter circuit may comprise a common-mode choke, and two series-connected capacitor having their junction connected to earth ground. Alternatively, the filter circuit may additionally comprise a differential-mode choke.
