A journeyman maintenance electrician was checking the phases on the legs of a three-phase current transformer. He was connecting bare alligator clip leads to a separable terminal on the secondary side of the transformer. He would then open the separable terminal by inserting a non-conducting object to separate the terminal. He was electrocuted when he removed a lead clip before the separating object was removed. The voltage was sufficient to cause an electric arc. A coworker said that the electrician might have forgotten to remote the separator object first or the alligator clip might have popped off and into the employee's hand. A device specifically designed for making the attachments was available but not ordered until after the fatality.
