Overview


This unit involves the skills and knowledge required to disconnect and reconnect electrical equipment connected to low voltage (LV) installation wiring. It includes preparing electrical equipment for disconnecting and then reconnecting equipment connected to LV installation wiring. It also includes inspecting and testing the reconnected electrical equipment for safe operation, identifying and reporting electrical faults and providing status reports. This must be incidental to a primary or regular function of the workplace. The unit excludes disconnecting or reconnecting circuits at a switchboard or to general electrical accessories (including switches, socket outlets and circuit protective devices), or installation of or alteration to any part of the fixed electrical wiring system (defined as electrical installation work). 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

For Melbourne campuses

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set & controlled parameters in accordance with each unit’s learning outcomes & 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 WHS/OHS requirements
*determining characteristics of electrical equipment
*selecting tools, equipment & testing devices
*identifying the point of isolation
*preparing to & disconnect/ reconnect electrical equipment

*isolating, testing & tagging accessories
*connecting a simple electrical circuit
*measuring voltage & current within a simple circuit
*producing a wiring diagram/ connecting a simple circuit following a wiring diagram & producing a schematic diagram
*using an analogue & digital multimeter for voltage measurement
*measuring resistance using a digital multimeter
*conducting insulation resistance tests
*checking the polarity of a three-core extension cord
*measuring current using a clip-on taking each circuit conductor in turn
*terminating cables using stud, screw, tunnel & lug terminal types
*identifying the type & arrangement of circuits supplying equipment that is to be disconnected
*testing the availability of supply for electrical equipment about to be disconnected
*locating isolation device/s
*determining the method of isolation to be used
*isolating a supply at a fuse & circuit breaker
*undertaking tests to determine if the electrical equipment is turned off
*using danger tags
*identifying the type & arrangement of circuits supplying equipment that is to be disconnected from a single phase &/or multiphase supply of voltages up to 1,000 V a.c. or 1,500 V d.c.
