Overview

This unit involves the skills and knowledge required to evaluate and modify low voltage (LV) lighting circuits, equipment and controls.
It includes working safely, identifying faults in luminaires and associated control equipment, repairing/replacing luminaire and control equipment components, ensuring all work complies with relevant Australian Standards and legislation, and completing work and documenting activities.
The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 volt (V) alternating current (a.c.) or 120 V direct current (d.c.).

Assessment

For Melbourne campuses

Assessment tasks will be designed to reinforce & extend knowledge and skill competence within set & controlled parameters in accordance with each unit’s learning outcomes & performance criteria requirements, incl the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.
Students will be expected to demonstrate the following required skills:

  • applying work health and safety (WHS)/occupational health and safety (OHS) workplace procedures, including:
  • identifying and assessing hazards and risks, and implementing control measures
  • checking circuits are isolated in accordance with workplace procedures and regulatory requirements
  • determining the operating parameters of existing lighting circuits and equipment
  • modifying existing lighting circuits and their controls to comply with specified operating parameters, including drawing and connecting lighting circuits that incorporate one-way, two-way
  • intermediate switching of light points using the loop at the light/switch methods of thermoplastic sheathed (TPS) wiring developing lighting circuits and equipment to comply with a specified function and operating parameters
  • determining the cause of low illuminance level in existing lighting circuits and equipment
  • determining conditions causing existing lighting circuits and equipment to be unsafe
  • connecting lighting equipment and controls
  • identifying faulty components in luminaires and auxiliary/control equipment from test results
  • testing luminaires and auxiliary/control equipment for serviceability
  • ensuring all work complies with relevant Australian Standards and legislation
