DEISGR606 : Switchgear for Power Distribution

Nominal duration: 24 hours total time commitment

This time commitment includes the structured activities, preparation reading, and attendance at each webinar, completing exercises, practical assessments and proctored assessments.

It is also expected that students spend additional time on readings, personal study, independent research and learning, practicing on remote labs and required software and working on any projects and assignments.

This module covers the basic purpose and functions of high, medium and low voltage switchgear and circuit breakers.


The purpose of the module is for participants to gain a broad knowledge of the fundamental purpose and functions of switchgear and circuit breakers that will aid in specification and management of power distribution systems.

MODIFICATION HISTORY Original module approved in 2010 (52368WA); April 2014 (52684WA).  This version is Version 3.


Modules that must be delivered and assessed before this module:

  • Fundamentals of Electrical Engineering and Power Distribution DEIFEP601

Modules that must be delivered concurrently with this module:

  • N/A




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, structured assessments, samples and questioning. This will include short answer questions on the knowledge content, the use of remote and virtual labs, and writing tasks to apply the learning to academic tasks.


Assessor Requirements:

Assessors must satisfy the assessor requirements in the standards for registered training organisation (RTOs) current at the time of assessment.

Assessors must also hold a tertiary qualification in engineering or related field.

The RTO must also ensure that trainers and assessors keep their industry knowledge up to date through ongoing professional development.

Assessment Conditions:

Questioning techniques should not require language, literacy and numeracy skills beyond those required in this module. 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.

Assessments may be open book assessment and may be completed off campus. Invigilation software will be used for some assessments to ensure authenticity of work completed.

Model answers must be provided for all knowledge-based assessments to ensure reliability of assessment judgements when marking is undertaken by different assessors.


On successful completion of this module students will be able to:

  1. Explain the basic purpose and function of high, medium and low voltage switchgear
  2. Explain the purpose and function of high, medium and low voltage circuit breakers
