Evidence Required

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 apply electrical principles to ensure safe practice assist with systems development component selection and maintenance and broadly evaluate electrical features functions and performance of machines or systems

This includes working individually and as part of a team and recognising and complying with normal control procedures on engineering projects

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

Assessors must be satisfied that the candidate can competently and consistently

identify effects and dangers of electricity

review sustainability implications functions and features of electrical devices machines and systems

assess and apply basic electrical principles and techniques

evaluate of suitability of electric power supply for applications

apply appropriate calculations and methods for electric motor control

ensure safe electrical working practice and compatibility of units in calculations

report and document results

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 then a simulated working environment 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

Where applicable reasonable adjustment must be made to work environments and training situations to accommodate ethnicity age gender demographics and disability

Access must be provided to appropriate learning andor assessment support when required Where applicable physical resources should include equipment modified for people with disabilities

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of the MEM Metal and Engineering Training Package

Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.

Assessment methods must confirm consistency and accuracy of performance over time and in a range of workplace relevant contexts together with application of underpinning knowledge

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application

Assessment may be applied under projectrelated conditions real or simulated and require evidence of process

Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance but is able to be transferred to other circumstances

Assessment may be in conjunction with assessment of other units of competency where required

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed

Range Statement

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.

isolation, shutdown and emergency cut-offs

lighting

heating, cooling and ventilation

average and maximum load, power factor, switch board layout, earthing and protection systems and power consumption and cost

Electrical-related engineering tasks

Electrical-related engineering tasks covered by this unit include, but are not limited to:

determining WHS, regulatory and risk management requirements

evaluating electrical supply options

technical evaluation of options for electrical equipment and components against peformance, cost and reliability requirements

determining methods for start, stop, speed control and reversing of a range of electric motors

risk assessments

registration requirements

safe work practices

state and territory regulatory requirements applying to electrical work

Standards and codes

Standards and codes refer to all relevant Australian and international standards and codes applicable to a particular mechatronic analysis task

Systems thinking

Systems thinking refers to the conduct of engineering work in a manner that demonstrates knowledge of how the interaction of different technical systems on equipment, machinery or structures, as well as the skills and techniques of personnel, combine to perform or support engineering-related operations, processes or projects. It embraces determining or establishing how the function of each technical system or component, as well as the skills and techniques of personnel, effects or potentially may effect, outcomes. Systems should be interpreted broadly within the context of the organisation and depending on the project or operation can include equipment, related facilities, material, software, internal services and personnel, and other organisations in the value chain

Life cycle assessment

Life cycle analysis can be used to improve sustainability of products and services. It may be applied to:

all aspects of manufacture of a single product

the entire operations of an organisation

a particular aspect of operations, such as environmental implications

Sustainability implications

Sustainability is used to mean the entire sustainable performance of the organisation/plant, including:

meeting all regulatory requirements

conforming to all industry covenants, protocols and best practice guides

minimising ecological and environmental footprint of process, plant and product

maximising economic benefit of process plant and product to the organisation and the community

minimising the negative WHS impact on employees, community and customer
