This unit involves the skills and knowledge required to locate and rectify faults in low voltage (LV) electrical equipment.
It includes following workplace procedures to inspect and test electrical equipment, identify and rectify faults and complete reporting. This must be incidental to a primary or regular function of the workplace. The Range of Conditions describes exclusions for this unit of competency.
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.).
The skills and knowledge described in this unit may require a license to practice in the workplace where plant and equipment operate at voltage above 50 V a.c. or 120 V d.c. However other conditions may apply in some jurisdictions subject to regulations related to electrical work. Practice in the workplace and during training is also subject to regulations directly related to occupational health and safety and where applicable contracts of training such as apprenticeships.
Additional and/or other conditions may also apply under State and Territory legislation and regulations related to licencing, electrical work and work health and safety (WHS)/occupational health and safety (OHS) regulations, which must be confirmed prior to commencing this unit.In some jurisdictions additional information related to licencing may be required on certification documentation. Further guidance can be found in the UEE Electrotechnology Training Package Companion Volume Implementation Guide.
Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit’s learning outcomes and performance criteria requirements, including 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 relevant work health & safety (WHS)/occupational health & safety (OHS) requirements
*dealing with unplanned events
*using routine fault-finding techniques, workplace procedures & problem-solving techniques to locate & rectify faults in LV electrical equipment
*following safe work method statements & procedures
*using wiring diagrams to assist in identifying fault locations
*identifying, inspecting, testing & isolation of electrical equipment
*preparing to replace, implementing repairs & reconnecting electrical equipment
*applying safe procedures to discharge a capacitor
*returning to service & testing for polarity, continuity & insulation resistance
*using safe working practices when carrying out fault finding
*identifying common types of electrical faults (open circuit, short circuit, partial open circuit & partial short circuit)
*interpreting ratings from nameplates for comparison with any replacement
*visual checking techniques on a range of single & multi-phase equipment
*using test instrumentation, safely conduct procedures to identify faults in a range of single & multi-phase equipment
*rectifying all identified faults & ensuring appropriate consultation/approval before implementing contingencies
*checking repaired equipment for safe & correct operation
*producing reports & documents for the identification & rectification of faults in electrical LV equipment in accordance with workplace procedures & regulatory & compliance documentation.
The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by Victoria University and/or via the Victoria University e-learning system.
