Unit of competency
Modification History
Release 1. Supersedes and is equivalent to MEM09205A Produce electrical schematic drawings.
Application
This unit of competency defines the skills and knowledge required to produce electrical schematic drawings complying with Australian and international standards and is primarily for those working within a drafting work environment with engineering or manufacturing applications.
Critical dimensions and specifications for the drawing are predetermined and drawings are produced under supervision. Drawings may be carried out with or without the use of computer-aided design (CAD) systems, and show the physical arrangement of components, electrical circuits and connections between devices, using appropriate symbols. A matching reference list of circuit components is also produced.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Pre-requisite Unit
MEM09204 Produce basic engineering detail drawings
MEM09229 Read and interpret technical engineering drawings
Competency Field
Drawing, drafting and design

Performance Evidence
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include:
- following work instructions, standard operating procedures (SOPs) and safe work practices
- determining purpose and scope for drawing requirements relevant to the project utilising all available information
- determining the function and purpose of circuit and its discrete components and assemblies and confirming through consultation with appropriate personnel
