Application
This unit describes the performance outcomes required to install vehicle, vessel or machinery low voltage (LV) direct current (DC) lighting and wiring systems that are not an integral part of vehicle or machinery controller area network databus (CAN-bus) topography. It involves preparing for the task, installing and testing the operation of lighting and wiring systems, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. LV lighting and wiring systems include those in agricultural machinery, heavy commercial vehicles, light vehicles, vessels, mobile plant machinery, motorcycles or outdoor power equipment.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

post-installation testing procedures, including:
confirming that electrical system is operating to manufacturer specifications following installation
confirming that no other problems are present as a result of installing LV DC lighting and wiring systems.
Assessment Conditions
Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the lighting and wiring systems that they have installed, e.g. work orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive repair workplace or simulated workplace
workplace instructions
two different vehicles, vessels or machinery requiring the installation of LV DC lighting and wiring systems
materials appropriate for installing LV DC lighting and wiring systems
equipment, and hand and power tools appropriate for installing LV lighting and wiring systems.
Foundation Skills
