This unit involves the skills and knowledge required to develop detailed and complex drawings for electrical systems using computer-aided design (CAD) systems.

It includes 2-D and 3-D drawing formats covering a representative range of electrical systems, such as installations with alternative supplies, installations over 400 ampere (A) per phase at low voltage (LV) and/or high voltage (HV), single or multi-tenancies, heavy plant, switchgear, protection systems, earthing, power factor correction, control equipment, and energy monitoring and management.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria on at least two separate occasions and include:

applying graphical techniques to produce products, processes, systems or services design representations

applying knowledge of complex electrical equipment design drawing methods, techniques, procedures and protocols and documenting design

applying relevant work health and safety (WHS)/occupational health and safety (OHS) requirements, including

using risk control measures

developing a variety of detailed and complex electrical drawings

incorporating feedback into final products

interpreting and using technical data and specifications

preparing to develop detailed and complex drawings for electrical systems

presenting designs of electrical engineering products, processes, systems or services

producing drafting documentation

selecting relevant computer-aided design (CAD) software tools, components, materials and equipment.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

managing resources

relevant advanced CAD systems

relevant CAD modelling techniques

relevant computer-based modelling, design, drafting and application systems

relevant graphical engineering design techniques for products, processes, systems or services representation

relevant manufacturer specifications and operating instruction

relevant job safety assessments or risk mitigation processes

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must occur in suitable workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated suitable workplace operational situations that replicate workplace conditions.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Resources for assessment must include access to:

a range of relevant exercises, case studies and/or simulations

relevant and appropriate materials, tools, facilities and equipment currently used in industry

resources that reflect current industry practices in relation to developing detailed and complex drawings for electrical systems

applicable documentation, including workplace procedures, equipment specifications, regulations, codes of practice and operation manuals.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.

Range is restricted to essential operating conditions and any other variables essential to the work environment.

Non-essential conditions may be found in the UEE Electrotechnology Training Package Companion Volume Implementation Guide.
