Release 1. This is the first release of this unit of competency in the UET Transmission, Distribution and Rail Sector Training Package.

This unit involves the skills and knowledge required to maintain traction overhead wiring systems in the electricity supply industry (ESI).

It includes maintaining and repairing overhead traction wiring systems on or about the running line/track and preparing for stringing and profiling, including isolating systems and circuits for safe working. It also includes diagnosing faults, modifying and adjusting to appropriate standards, identifying and implementing road/rail management plans, issuing/accepting electrical permits, recommissioning tests to ensure integrity of traction system prior to returning to service and updating system data and/or maintenance records.

The application of the skills and knowledge described in this unit may require a licence/registration to practice in the workplace.

Other conditions may apply under state and territory legislative and regulatory licensing requirement which must be confirmed prior to commencing this unit.
