Abstract: An employee had replaced an electric motor on the feed line to a feed screw conveyor. The wiring for the motor was installed incorrectly. The equipment grounding conductor for the motor was loose in the attachment plug (i.e., it was not connected). The power supply cord for the motor apparently had a loose conductor, which was in contact with the metal housing of the motor. The motor was connected to the metal feed conveyor. As a result of the ground fault, the metal conveyor frame was energized. As the employee was cleaning the bottom of the feed opening, he touched the metal frame with his hand and was electrocuted. A coworker found him slumped under the conveyor.
