10) This relates to the competency standard unit as a whole providing the range of contexts and conditions to which the Performance Criteria apply. It allows for different work environments and situations that will affect performance. Inspection should be planned with the appropriate parties to determine access, conditions and work requirements. Equipment may include a.c. motors, alternators, d.c. 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, elements, seals, motor bearings and brushgear. Test and measurement instruments may include tong testers, insulation resistance/continuity tester, multimeters, ductor tester, overload injection tester and growlers. Work may be performed with equipment on line. 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. Generic terms are used throughout this Training Package for vocational standard shall be regarded as part of the Range Statement in which competency is demonstrated. The definition of these and other terms are given in Section 2.1.00 Preliminary Information and Glossaries. |
