Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

Cuircuit Theory

Course Description

This learning unit introduces the principle of electrical design process.
Students will develop practical skills in design; testing and problem solving related to electronic communication circuits in practical activities and work simulation projects.

This course covers the theory and application for the following concepts:
• The fundamental principles of electrical design.
• Design requirements in an electrical installation.
• The principles of producing adequate illumination for various tasks.
• Applications of AS3000 and AS3008.1

Learning Outcomes



Details of Learning Activities

• Classroom tutorial activities to consolidate the theory of electrical protections, installation design principles, installation for various electrical devices, metering, basic lighting principles, various electrical heating and hazardous areas.

• Practical activities to develop skill in selection and installation of protective devices, various cables, switchboard, control panels and lightings.


• Work simulation projects/assignments involving lighting and power design for an industrial installation. Produce installation drawing for lighting, power and switchboard layout drawing according to relevant Australian standards, select appropriate light fittings and lamps. The power installation design will include the calculations relating to the demand & volt drop considerations and fault conditions. Specifications will be provided with work simulation (team or individual basis) or may be negotiated to suit a workplace based application.

Overview of Assessment

• Written assessment.

•Three  Class Assignments


• Class participation and performance


• A Pass in practical performance in laboratory exercises


Assessment Tasks

Assessment activities will be as close as practicable to real work situations and will require “real work” type decision-making by the student. Evidence of competent performance shall be gathered from:

• Projects and assignments

These projects have to be undertaken toward the end of the unit, in a controlled environment for the specified duration in order to perform tasks autonomously and/or a member of a team .

• Practical exercises

These will be assessed progressively according to individual task criteria. All practical exercises must be:
- Undertaken according to safe working practice as specified by the School.
- Perform according to specified laboratory standards and practice including calibration, measurement and accurate reading. This must includes electrical measurement taken with safe working practice, meters properly calibrated, meter settings positioned for an accurate reading and accurate readings taken for all measurements.

• Progressive and Validation Tests

Theoretical concept underpinning measurement and testing procedures will be assessed progressively in tests throughout the unit. A written/ oral validation test will also apply to aspects of projects done in groups


Although this learning unit will be assessed on completion, the competency itself will not be signed off until this and further learning units are completed and the student is deemed competent.


Assessment requirements include:

- attendance and satisfactory completion of prescribed practical exercises , which may be scheduled during the day or evening depending on the demand.
- evidence of participation in and satisfactory completion of work simulation projects.
• satisfactory completion of class assignment work
• progressive assessments
• timely submission and standard presentation for all assessment material / documentation
