Course Description

This unit involves the skills and knowledge required to ascertain correct operation of single and three phase alternating current (a.c.) circuits and solving circuit problems as they apply to servicing, fault finding, installation and compliance work functions.

It includes safe working practices, multi-phase circuit arrangements, issues related to fault protection, power factor and multiple earthed neutral (MEN) systems and solutions to circuit problems derived from calculated and measured parameters.

The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 volt (V) a.c. or 120 V direct current (d.c.).

Competency development activities in this unit are subject to regulations directly related to licensing. Where a licence or permit to practice is not held, a relevant contract of training, such as an Australian Apprenticeship, may be required.

Additional and/or other conditions may apply in some jurisdictions subject to regulations related to electrical work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations.

Assessment 4 (Task 7): Final Test
Theoretical concept covered in weeks 9 to 16 will be assessed by a Final Test in week 17 / 18.

To be deemed competent, student must achieve satisfactory (S) results in ALL assessments / Tasks.

This course is assessed as Competent or Not Yet Competent and subsequently the following course results are allocated:

CA - Competency Achieved

NYC - Not Yet Competent

DNS - Did Not Submit for Assessment.

Assessment Due Dates:

All assessment tasks will have a due date provided and published in Canvas. Assessments submitted after the due date will not be accepted unless an extension has been provided or special consideration has been granted.

Assessment Re submissions (if Unsatisfactory):

You will be allowed ONE re-submission attempt FOR EVERY ASSESSMENT (if unsatisfactory). You will be provided with a new due date by your teacher for your re-submission attempt if a re-submission is required.
