The evidence guide specifies the evidence required to demonstrate achievement in the unit of competency as a whole. It must be read in conjunction with the unit descriptor, performance criteria, range statement and the assessment guidelines for the Metal and Engineering Training Package |
Overview of assessment requirements | A person who demonstrates competency in this unit must be able to disconnect/reconnect fixed wired equipment over 1000 volts a.c./1500 volts d.c. Competency in this unit cannot be claimed until all prerequisites have been satisfied. |
Context of 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. |
Interdependent assessment | This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with disconnecting/reconnecting fixed wired equipment over 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 of competency. 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. |
Consistency of performance | 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. |
Required skills | Look for evidence that confirms skills in: |
determining and recording equipment characteristics from relevant circuit diagrams, specifications, schematics |
correctly identifying the point(s) of isolation of fixed wired equipment |
proving electrical isolation |
isolating fixed wired equipment |

identifying possible risks associated with this work |
reading and interpreting routine information on written job instructions, specifications and standard operating procedures |
following oral instructions |
Required knowledge | Look for evidence that confirms knowledge of: |
any applicable industry standards, national/Australian standards, NOHSC guides, State/Territory regulatory codes of practice/standards |
use and application of personal protective equipment for disconnecting/reconnecting fixed wired equipment over 1000 volts a.c.1500 volts d.c. |
safe work practices and procedures |
characteristics of the circuit and the equipment |
hazards associated with the circuits and the equipment |
relevant regulatory requirements |
|
point(s) of isolation for the fixed wired equipment and reasons for selecting the particular isolation point(s) |
reasons for using earthing, lock-off equipment and signs |
clearances from live parts |
safe isolation |
specifications for the connections to be made |
operational specifications of the fixed wired equipment |
potential dangers of the work covered in this unit |
recognised procedures for the movement and treatment of the injured person |
appropriate local medical and rescue services |
