Elements and Performance Criteria

Stream: Production Plant
Field: Maintenance
Equivalencies: This unit of competence is based on unit 5.5 of the Electrical Contractors
Industry Association Competency Standards (electrical stream)
Inspection should be planned with the appropriate parties to determine access, conditions and work requirements
Equipment may include AC motors, alternators, DC motors, generators, pumps, electro/mechanical motor starters, low voltage transformers/switchgear and associated control panels, motor operated valves, hoists and cranes, arc welders, resistive heaters, hot water units, exhaust fans, luminaries, batteries, metal detectors, general low voltage lighting, power circuits, control/indication and alarm circuits, electrical tools/appliances, workshop machinery and compressors
Materials may include masonry anchors, bolts, nuts, washers, screws, rivets, saddles, clips, brackets, solvents, adhesives, insulation tapes, heat shrink, sleeving, spiral binding, cable ties, solder, lubricants, oils, greases, sealants, lugs, connectors, terminal blocks, cable markers and identification labels
Components may include fuses/circuit breakers, earth leakage breakers, timers, contactors, contacts, coils, relays, resistors, ballasts, capacitors, solenoids, overloads, switches, plugs, busbar, cable, fans, thermostats, , seals, motor bearings and brushgear
Test and measurement instruments may includemultimeters, tong testers, insulation resistance/continuity tester, ductor tester, overload injection tester and growlers
Fault finding and diagnostic techniques may include linear approach, half split rule, sensory detection, loop test, insulation/resistance and continuity tests
Fault indicators may include indication lamps, LED's, alarms and flag relays
Work may be performed with equipment online
Work completion details may include, plant and maintenance records, job cards, check sheets and on device labelling updates
Work site environment may be affected by nearby plant or processes, e.g. heat, noise, dust, oil, water and chemical
Isolations can refer to electrical/mechanical or other associated processes

Critical aspects of evidence
The knowledge and application of relevant sections of: Occupational, health and safety legislation; Statutory legislation; Enterprise/site safety procedures; Enterprise/site emergency procedures
Attainment of electrical licence, deeming competency associated with electrical work
Preparation and planning of work
Verification techniques
Diagnostic and fault finding techniques and procedures
Repair techniques and procedures
Completion of work procedures
Context of assessment
Competency Standards should be assessed in the workplace or simulated workplace and under the normal range of workplace conditions
Assessment of this unit will be supported with documentary evidence, by means of endorsement stating type and application of work
Interdependent assessment of unit
