Elements and Performance Criteria

1. Disconnect equipment
   • Electrical characteristics of equipment and circuit are determined by reference to circuit drawings, schematics, reference manuals, equipment specifications, identification plates and/or consultation with technical adviser.
   • Where appropriate, equipment characteristics are determined and recorded to standard operating procedures (rotation etc.).
   • Points of isolation are identified using correct and appropriate procedures incorporating access permits where required.
   • Equipment is isolated using correct and appropriate techniques and procedures.
   • All lock-off equipment and signage requirements are used correctly and appropriately.
   • Electrical isolation is proven using correct and appropriate techniques, procedures and test equipment.
   • Conductor layout is noted, recorded and labelled to standard operating procedures.
   • Conductors are disconnected using correct and appropriate techniques, procedures, tools and equipment.
   • Disconnected cables/connections are made safe to standard operating procedures and access permits are issued where required.
2. Connect equipment
   • Characteristics of the equipment to be connected are identified and connection requirements are determined.
   • Circuit is checked for safe isolation using correct and appropriate techniques, procedures and test equipment.
   • Connections are checked and prepared for termination using correct and appropriate tools and procedures.
   • Conductors are connected to equipment to specifications using correct and appropriate techniques, tools and equipment.
   • All cables/wires/conduit are fastened/sealed to specifications, using correct and appropriate techniques, tools and equipment.
   • All lock-off equipment and signage is removed using standard operating procedures.
   • Equipment and circuit is checked and tested for compliance to specifications using correct and appropriate techniques, procedures, tools and equipment.
3. Perform emergency first aid
   • Situation is assessed to identify points of danger to the injured person and potential rescuer.
   • Rescue/recovery of injured person or assistance to injured person is undertaken in accordance with recognised standards/procedures and contact is made with appropriate medical and rescue authorities.
   • Details of first aid given are recorded.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	A person who demonstrates competency in this unit must be able to disconnectreconnect fixed wired equipment over volts ac volts dc Competency in this unit cannot be claimed until all prerequisites have been satisfied
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria including required knowledge and be capable of applying the competency in new and different situations and contexts
Context of and specific resources for assessment	This unit may be assessed on the job off the job or a combination of both on and off the job Where assessment occurs off the job that is the candidate is not in productive work then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team The assessment environment should not disadvantage the candidate This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with disconnectingreconnecting fixed wired equipment over volts ac volts dc or other units requiring the exercise of the skills and knowledge covered by this unit
Method of assessment	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 supervisors reports project work samples and questioning Questioning techniques should not require language literacy and numeracy skills beyond those required in this unit of competency 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

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Appropriate techniques and procedures	Includes clearances for safe approach as mandated by statutory authorities
Isolation	Isolating supply for safe disconnection of all electrical power to equipment supply circuit with switch circuit breaker or fuses etc.
Connection	Disconnection/reconnection and making safe for maintenance of equipment
