Title	Part 21 Report for Potential Safety Hazard on Speed Switch Installed on Emergency Diesel Generator (Edg)
Event Description	The following was received via fax: [Fairbanks Morse (FM) determined] that when the speed switch assembly was mounted on a conductive surface, the voltage regulator grounded out the 24 volt direct current power through the heat sink preventing the speed switch from operating. This condition was not detected prior to the first speed switch being shipped to Hope Creek in September, 2010. It was never installed on the EDG prior to being recalled. The unit was returned to FM and has since been reworked and verified to be in compliance with the latest design to eliminate the deficiency.
