This unit involves the skills and knowledge required to diagnose and repair faults in electrical and electronic systems.

Diagnosing and repairing faults is the process of optimising electrical and electronic systems through regular inspections and verification to meet efficiency and operational requirements.

Competency in this unit requires the ability to plan work, verify faults, find faults, determine cause of fault, repair and to report on all completed work tasks. Individuals will, in general, work under supervision in an electrical, electronic and/or mechanical equipment repair workshop or on site.

Power generation maintenance personnel are typically trained and authorised to receive permits to work.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Note: Workplace practice

The application of the skills and knowledge described in this unit of competency may require a licence or training permit to practice in the workplace, where work is carried out on gas and electrical installations. Additional and/or other conditions may apply under state and territory legislative and regulatory licensing requirements.
