Application
This unit of competency defines the skills and knowledge required to diagnose, locate and rectify faults in electrical equipment/components up to 1000 volts a.c./1500 volts d.c. single and multi-phase power where these are disconnected from the electrical supply.
It covers basic mechanical disconnection, dismantling and reassembly of equipment components, enclosures and drives.
Where disconnection and reconnection of fixed-wired equipment is required unit MEM18049 Disconnect/reconnect fixed wired equipment up to 1000 volts a.c./1500 volts d.c. should also be selected.
Where work involves up to 250 volt single phase supply only then unit MEM18045 Fault find and repair electrical equipment/components up to 250 volts single phase supply should be selected.
Some jurisdictions may require the holder of this unit to be licensed or certified and users should check with the relevant authorities.

Assessment Requirements
Performance Evidence
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:
following work instructions, standard operating procedures (SOPs) and safe work practices
identifying and interpreting specifications, charts, lists, circuit drawings, schematics, regulatory and legislative requirements to fault find and repair electrical equipment/components up to 1000 volts a.c./1500 volts d.c.
checking that the electrical equipment/components are isolated and tagged where necessary in strict accordance with work health and safety (WHS) requirements and procedures
locating and reading/recording built-in indicators and error codes
checking and testing electrical equipment and components on non-interconnected circuits for correct operation and/or compliance with specifications
identifying and localising faults in electrical equipment and components using appropriate fault finding techniques using appropriate fault finding techniques and test equipment and recording/reporting faults in accordance with SOPs
repairing/replacing or adjusting electrical equipment/components to specifications and selecting replacement parts using manufacturers’ catalogues and data
verifying that the electrical equipment/components are operating to specifications
recording rectification activities in accordance with SOPs.
Knowledge Evidence
Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:
safe work practices and procedures and use of personal protective equipment (PPE)
function of the electrical equipment/component within the circuit
relevant regulatory requirements
electrical equipment/component isolation and tagging procedures
test equipment to be used to verify isolation of the electrical equipment/circuit
errors indicated by built-in devices
procedures for:
testing electrical equipment/components for correct operation
localising faults in electrical equipment/components
recording/reporting faults in electrical equipment/components
recording electrical equipment/component rectification
tools, equipment and techniques to be used to test the operation of the electrical equipment/component and reasons for selection
specifications of the electrical equipment/component
variations between test results and specifications
appropriate techniques/procedures for returning and confirming the electrical equipment/components have been returned to specification
adjustments that can be made to electrical equipment/components.
Assessment Conditions
Assessors must:
have vocational competency in fault finding/repairing electrical equipment/components up to 1000 volts a.c./1500 volts d.c. at least to the level being assessed with relevant industry knowledge and experience
satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires
Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills
Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
