Application
This unit of competency defines the skills and knowledge required to locate and repair/rectify faults in interconnected electrical circuits.
It applies to work on interconnected electrical circuits where electrical equipment and/or components are connected electrically, that is, there are multiple electrical power supplies or sources, voltages or circuits which are found in the control or switching of the circuit.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
This unit has dual status and is to be regarded as both a Specialisation Band A unit and Specialisation Band B unit for progression to C5 (AQF level V).
Band: A
Unit Weight: 6
