Facility personnel were performing a configuration control inspection of the Space and Security Power Systems Facility exhaust control panel. Drawing discrepancies had been noted based on recent activities and personnel were attempting to verify configuration of the panel versus the documentation on the as built drawing. During the inspection a conductor was discovered with a frayed end that led back to a 24V relay. The conductor appeared to be abandoned in place. After a discussion with the instrument technician involved personnel decided the frayed end should be removed and a wire nut installed. The work was performed and the facility Shift Supervisor was notified of the conditions and actions taken.

A subsequent inspection by facility management and the instrument technician revealed exposed 120VAC in the cabinet. There was no voltage on the cut wire.
