Description
This unit of competency covers the skills and knowledge required to produce electrical schematic drawings to comply with Australian Standard (AS) 1102.101-1989 Graphical symbols for electrotechnical documentation - General information and general index, or equivalent, using predetermined design specifications. The unit also covers the production of layout or block diagrams to show the physical arrangement of components.
Notes
Elements and Performance Criteria
1 Determine schematic drawing requirements

  • 1.2 Interpret available information relevant to project and work requirements, and identify and address further information needs
  • 1.3 Identify and prepare equipment required to complete work
  • 1.4 Identify and access organisational files, templates and symbols as required for work
2 Identify system requirements
  • 2.1 Identify and apply relevant codes, standards and symbols used for electrical diagrams and drawings
  • 2.2 Identify function and purpose of circuit and its components and assemblies
  • 2.3 Identify environmental implications of inefficient systems and strategies for minimising impact
3 Prepare electrical drawings and diagrams
  • 3.1 Lay out drawing in accordance with the sketches and specifications
  • 3.2 Prepare an electrical block diagram in accordance with Australian Standards
  • 3.3 Draw cable run and riser diagrams from schedules
  • 3.4 Produce switchboard layout drawings
  • 3.5 Prepare single line and interconnecting electrical diagrams in accordance with Australian Standards
  • 3.6 Prepare wiring and circuit diagrams in accordance with Australian Standards
  • 3.7 Ensure drawing accurately reflects specifications, is presented according to organisational requirements and contains all relevant information, including correct line work, scales, notation and dimensioning
  • 3.8 Apply workplace occupational health and safety (OHS) and environmental procedures
4 Prepare materials list
  • 4.1 Where required, select components and/or materials from supplier/manufacturer catalogues using predetermined specifications
  • 4.2 Produce a parts list in accordance with workplace procedures
  • 4.3 Store drawings and/or materials list according to workplace procedures
5 Consult appropriately with other disciplines
  • 5.1 Verify the parameters of the brief and clarify specifications with appropriate personnel
  • 5.2 Identify and consult with support services
  • 5.3 Present and explain drawings at appropriate stages of the project

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 interpret and apply drawing specifications in the production of electrical diagrams and drawings to Australian Standard AS1102.101-1989 Graphical symbols for electrotechnical documentation - General information and general index, or equivalent.
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.
Specifically the candidate must be able to:
work within typical site/teamwork structures and methods
apply worksite communication procedures
comply with organisational policies and procedures, including quality requirements
participate in work meetings
comply with quality requirements
use industry terminology
apply appropriate safety procedures
obtain required information for work and produce detailed electrical/electronic schematic drawings in accordance with AS1102.101-1989 Graphical symbols for electrotechnical documentation - General information and general index, or similar.
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.
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 and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with drafting 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.
