This relates to the unit of competency 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.
This Competency Standard Unit shall be demonstrated in the installation and maintenance of de-energised high voltage and low voltage underground polymeric cables and includes underground services, network infrastructure, the jointing, terminating and repair of cables. It encompasses working safely, visual inspections and mandatory and functional test procedures, identifying non-compliance defects and mandatory reporting requirements
Test and recording equipment may include digital/analogue voltage detectors, multimeters, phase rotation testers, load testers, continuity testers, tong ammeters, cable identification and spiking equipment and insulation resistance testers.
Testing procedures may include continuity, polarity, phase rotation, insulation resistance and voltage.
Installation may include, the laying and connection of cables, connection of the cable to underground equipment, the fitting and connection of fuses or circuit breakers and the testing and commissioning of the cable.
Maintenance may include the removal, repair and replacement of electrical equipment encompassing “like for like” and associated hardware as well as the termination and/or connection of this equipment according to requirements and the temporary installation of services and associated equipment. It also encompasses the identification of faults; the pre-commissioning tests involving the equipment/system and the interpretation of these tests against agreed specifications.
Service includes the connection between the customers’ point of supply and the underground pillar/pit connection (single phase), underground pillar/pit connection (three phase) and or underground to overhead connection.
Electrical equipment and associated hardware may include relevant transmission or distribution network; switchgear (e.g. reclosers, sectionalisers, drop-out fuses, disconnectors, isolators, air break switches, gas filled switches, fuse switches ); transformers (e.g. padmount, pole-mounted and mobile); reactors; fault indicators; regulators;; capacitors; relays (simple); mobile generators and surge arrestors; support brackets and the like.
Jointing and terminating equipment and locations may include circuit breakers, contactors, mains connection boxes, links, fuses, disconnect boxes, ring main units, distribution fuse boxes, pad mount and ground transformers, chamber substations, LV switchboards, pillars/turrets, busbar/termination boxes, street lighting control points and street lighting columns.
Jointing and terminating materials may include compound and resin filled boxes, polymeric tape materials, polymeric heat shrink materials, "slip-on" moulded components and pre-stretched polymeric materials, compression, welded and mechanical connectors.
It does not include the energisation of equipment in a highly complex, interdependent and interconnected electricity supply network system, where the effects of unintended consequences on the system are high risk and appropriate personnel effect energisation.

EVIDENCE GUIDE
9) This provides essential advice for assessment of the unit of competency and must be read in conjunction with the performance criteria and the range statement of the unit of competency and the Training Package Assessment Guidelines.
The Evidence Guide forms an integral part of this Competency Standard Unit and shall be used in conjunction with all component parts of this unit and, performed in accordance with the Assessment Guidelines of this Training Package.

Overview of Assessment
9.1)

Longitudinal competency development approaches to assessment, such as Profiling, require data to be reliably gathered in a form that can be consistently interpreted over time. This approach is best utilised in Apprenticeship programs and reduces assessment intervention. It is the Industry’s preferred model for apprenticeships.
However, where summative (or final) assessment is used it is to include the application of the competency in the normal work environment or, at a minimum, the application of the competency in a realistically simulated work environment. It is recognised that, in some circumstances, assessment in part or full can occur outside the workplace. However, it must be in accord with Industry and, Regulatory policy in this regard.
Methods chosen for a particular assessment will be influenced by various factors. These include the extent of the assessment, the most effective locations for the assessment activities to take place, access to physical resources, additional safety measures that may be required and the critical nature of the competencies being assessed.
The critical safety nature of working with electricity, electrical equipment, gas or any other hazardous substance/material carries risk in deeming a person competent. Hence, sources of evidence need to be ‘rich’ in nature so as to minimise error in judgment.
Activities associated with normal every day work have a bearing on the decision as to how much and how detailed the data gathered will contribute to its ‘richness’. Some skills are more critical to safety and operational requirements while the same skills may be more or less frequently practiced. These points are raised for the assessors to consider when choosing an assessment method and developing assessment instruments. Sample assessment instruments are included for Assessors in the Assessment Guidelines of this Training Package.

Critical aspects of evidence required to demonstrate competency in this unit
9.2)

Before the critical aspects of evidence are considered all prerequisites shall be met.
Evidence for competence in this unit shall be considered holistically. Each element and associated performance criteria shall be demonstrated on at least two occasions in accordance with the “Assessment Guidelines - UET12”. Evidence shall also comprise:
A representative body of performance criteria demonstrated within the timeframes typically expected of the discipline, work function and industrial environment. In particular this shall incorporate evidence that shows a candidate is able to:
Implement Occupational Health and Safety workplace procedures and practices including the use of risk control measures as specified in the performance criteria and range; and
Apply sustainable energy principles and practices as specified in the performance criteria and range; and
Demonstrate an understanding of the essential knowledge and associated skills as described in this unit to such an extent that the learner’s performance outcome is reported in accordance with the preferred approach; namely a percentile graded result, where required by the regulated environment; and
Demonstrate an appropriate level of employability skills; and
Conduct work observing the relevant Anti Discrimination legislation, regulations, policies and workplace procedures; and

Context of and specific resources for assessment
9.3)

This unit should be assessed as it relates to normal work practice using procedures, information and resources typical of a workplace. This should include:
OHS policy and work procedures and instructions.
Network construction standards
Network supply standards
Suitable work environment, facilities, equipment and materials to undertake actual installation, maintenance, testing and verification on de-energised low voltage underground polymeric cables.
In addition to the resources listed above, in context of and specific resources for assessment, evidence should show demonstrated competency working below ground, in limited spaces, with different structural/construction types and method and in a variety of environments.

Method of assessment
9.4)

This Competency Standard Unit shall be assessed by methods given in Volume 1, Part 3 “Assessment Guidelines”.
Note:
Competent performance with inherent safe working practices is expected in the Industry to which this Competency Standard Unit applies. This requires that the specified essential knowledge and associated skills are assessed in a structured environment which is primarily intended for learning/assessment and incorporates all necessary equipment and facilities for learners to develop and demonstrate the essential knowledge and associated skills described in this unit.

Concurrent assessment and relationship with other units
