What an assessment for MEM18105 must cover

49 assessable components: 5 elements (24 performance criteria), 10 performance evidence and 15 knowledge evidence requirements. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Determine job requirements

1.1Follow standard operating procedures (SOPs)
1.2Comply with work health and safety (WHS) requirements at all times, including appropriate risk control measures
1.3Use appropriate personal protective equipment (PPE) in accordance with SOPs
1.4Identify job requirements from specifications, drawings, job sheets or work instructions

2 Disconnect equipment

2.1Determine function of electrical of equipment by reference to circuit drawings, schematics, reference manuals, equipment specifications, identification plate and/or consultation with technical adviser
2.2Determine and record equipment characteristics, including direction of rotation, where appropriate
2.3Identify points of isolation and isolate equipment in accordance with procedures
2.4Check that circuits/equipment are isolated and tagged using all appropriate lock-off equipment and signage
2.5Note, record and label conductor layout
2.6Disconnect conductors and terminate and make safe disconnected cables/connections using appropriate tools, equipment and techniques

3 Prepare to reconnect equipment

3.1Plan reconnection ensuring WHS policies and procedures are followed
3.2Identify characteristics, including rating of the equipment to be connected, and determine connection requirements
3.3Test original and/or replacement item to ensure it is safe to be connected

4 Connect equipment

4.1Isolate and tag circuits and equipment in accordance with procedures
4.2Check connections and prepare conductors for termination
4.3Test the conductors for continuity and insulation resistance readings ensuring they comply with regulatory and legislative requirements
4.4Confirm continuity between exposed conductive parts of the equipment and the main earth or metal switchboard enclosure
4.5Connect conductors to equipment in accordance with specifications and regulatory requirements
4.6Fasten/seal all cables/wires/conduit to specifications
4.7Remove all lock-off equipment and signage

5 Perform emergency first aid

5.1Assess situation to identify points of danger to the injured person and potential rescuer
5.2Rescue/recover injured person or provide assistance to injured person in accordance with recognised standards/procedures
5.3Make contact with the appropriate medical and rescue authorities
5.4Record details of first aid given

Performance evidence

following work instructions, SOPs and safe work practices
identifying and interpreting specifications, charts, lists, circuit drawings, schematics, regulatory and legislative requirements to disconnect/reconnect HV fixed wired equipment
checking that the electrical equipment is isolated and tagged where necessary in strict accordance with WHS requirements and procedures using appropriate lock-off equipment and tags/signs
disconnecting equipment by labelling and recording conductors and making safe disconnected cables/connections using appropriate tools, test equipment, procedures and techniques
confirming isolation prior to reconnecting fixed wired equipment and checking connections and preparing conductors for termination in accordance with manufacturer specifications and regulatory requirements
testing conductors prior to connection to ensure continuity, and insulation resistance readings comply with following requirements: - checking continuity of the protective earth conductor to determine whether it is sufficiently low - testing the resistance between the protective earth conductor and the neutral conductor to determine whether it is sufficiently low – not greater than 2 Ohms - testing the insulation resistance of active conductors to confirm that it is greater than 1 Megohm - testing to ensure continuity is confirmed between the exposed conductive parts of the equipment and the main earth or metal switchboard enclosure
connecting conductors to equipment and fasten/seal cables/wires/conduits using appropriate procedures and tools to relevant specifications and regulatory requirements
removing all lock-off devices and signage and checking/testing equipment and circuits for compliance to specifications
rescuing/recovering of injured person in accordance with appropriate standards/procedures and provide first aid, including cardiopulmonary resuscitation (CPR) where appropriate, and contacting the appropriate medical and rescue authorities
recording details of first aid given.

Knowledge evidence

safe work practices and procedures and use of PPE
any applicable industry standards, national/Australian Standards, NOHSC guides, state/territory regulatory codes of practice/standards and relevant regulatory requirements
characteristics of the circuit and the equipment, including rating and rotation
points of isolation for the fixed wired equipment and reasons for selecting the particular isolation point) and reasons for using earthing, lock-off equipment and signs
clearances from live parts
safe isolation
operational specifications of the fixed wired equipment and connections to be made
procedures for confirming electrical isolation of fixed wired equipment and circuits
procedures, techniques, tools and equipment to be used for disconnecting/reconnecting conductors
test requirements to ensure compliant continuity and insulation resistance of conductors
test requirements to ensure continuity between exposed conductive parts of the equipment and the main earth or metal switchboard enclosure
potential dangers/risks associated with work
recognised procedures for the movement and treatment of the injured person, including HV rescue, clearing of airways, CPR, care of spinal injuries, treatment of cuts/lesions, burns/scalds and treatment of shock
appropriate local medical and rescue services
procedures for incident reporting.

Questions about assessing MEM18105

What does an assessment tool for MEM18105 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM18105 needs to address all 49 unit components: 5 elements with 24 performance criteria, 10 performance evidence requirements, 15 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for MEM18105?

Auditori pulls the current release of MEM18105 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for MEM18105 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM18105 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of MEM18105, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
