Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Interpret work order and locate and apply information.

Apply safety requirements, including the isolation of equipment and use of personal protective equipment.

Follow work instructions, operating procedures and inspection processes to:

minimise the risk of injury to self and others

prevent damage and wastage of goods, equipment and products

maintain required production output and product quality.

Modify a significant electrical system or sub-system including:

the selection, development and documenting of success factors and evaluation criteria before undertaking the modification

the selection, development and validation of the modification methodology, processes and specification

the application of the modification specification, methodology and process

the documenting and reporting of the outcomes.

Work effectively with others.

Modify activities to cater for variations in workplace context and environment.

Context of, and specific resources for assessment

Assessment may occur on the job or in a workplace simulated facility with process equipment, materials, work instructions and deadlines.

Access to operational electrical systems required modification, testing equipment as stipulated in the Range Statement, technical information and a work environment.

Method of assessment

Assessment of this unit of competence is most likely to be project related and require portfolios or other forms of indirect evidence of process. Direct evidence will include certification of compliance of the final outcome/product or authorisation for use by a competent authority.

Assessment must confirm the inference that competence is able not only to be satisfied under the particular circumstances, but is able to be transferred to other projects.

Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role.

Guidance information for assessment

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.

Electrical modifications

Electrical modifications to be covered by this unit may include those to:

vary the performance of DC motors to meet changes in operational requirements

vary the performance of alternators to meet changes in operational requirements
