Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | A person who demonstrates competency in this unit must be able to Fault find/repair electrical equipment/components up to 1000 volts a.c./1500 volts d.c. Competency in this unit cannot be claimed until all prerequisites have been satisfied. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts. |
Context of and specific resources for assessment | This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate. This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with fault finding/repair of electrical equipment/components up to 1000 volts a.c./1500 volts d.c., or other units requiring the exercise of the skills and knowledge covered by this unit. |
Method of assessment | Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials. |

(add new lines for each of the assessment tasks)
Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Required skills |
Look for evidence that confirms skills in: using diagnostic skills to identify correct and faulty operation interpreting and using circuit diagrams, specifications isolating electrical equipment/components from the power supply tagging isolated electrical equipment/components checking electrical equipment/components for isolation from the power supply locating and reading/recording built-in fault indicators obtaining error code interpretation documents checking and testing electrical equipment/components for correct operation verifying variations from specifications indicated by initial test results identifying and localising faults in electrical equipment/ components recording/reporting faults in electrical equipment/components repairing, replacing or adjusting electrical equipment/components to specification referencing supplier catalogues using test instruments to confirm that electrical equipment/components are operating to specification recording rectification of the electrical equipment/ components |
Required knowledge |
Look for evidence that confirms knowledge of: function of the electrical equipment/component within the circuit hazards associated with the electrical equipment/component relevant regulatory requirements electrical equipment/component isolation 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 tools, equipment and techniques to be used to test the operation of the electrical equipment/component reasons for selecting the chosen tools, equipment and techniques specifications of the electrical equipment/component variations between test results and specifications procedures for localising faults in electrical equipment/components procedures for recording/reporting faults in electrical equipment/components appropriate techniques/procedures for returning the electrical equipment/components to specification specifications of the electrical equipment/components adjustments that can be made to electrical equipment/components procedures for confirming the electrical equipment/components have been returned to specification procedures for recording electrical equipment/component rectification |
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. | |
Equipment | Single and multi phase motor drive and heating appliances, relays, coils, transformers, thermostats, gauges, illuminating devices, switches, circuit fuses and breakers, etc. using up to 1000 volts a.c.1500 volts d.c. power supplies on non-interconnected circuits |
Components | Brushes, armatures, windings, contactors, relays, programmable controllers or other electronic switching devices, switches, fuses, circuit breakers, relays, transformers, semi-conductor devices, regulators, motors, etc. |
Appropriate fault finding techniques | Testing for voltage, current, frequency, polarity, phase, circuit continuity, insulation resistance, earth continuity etc. |
Test equipment | Continuity testers, ammeters, voltmeters, multimeters, tong testers, wattmeters, cathode ray oscilloscopes etc. |
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
