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 plate and/or consultation with technical adviser.
   • Where appropriate, equipment characteristics are determined and recorded to standard operating procedures (rotation etc.).
   • Point/s of isolation are identified using correct and appropriate procedure.
   • 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 procedure.
   • Conductors are disconnected using correct and appropriate techniques, procedures, tools and equipment.
   • Disconnected cables/connections are terminated and made safe to standard operating procedures.
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 conductors are 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 are removed using standard operating procedures.
   • Equipment and circuit are checked and tested for compliance with 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. Contact is made with the appropriate medical and rescue authorities.
   • Details of first aid given are recorded.

Required Skills

Evidence Required

The evidence guide specifies the evidence required to demonstrate achievement in the unit of competency as a whole It must be read in conjunction with the unit descriptor performance criteria range statement and the assessment guidelines for the Metal and Engineering Training Package
Overview of assessment requirements	A person who demonstrates competency in this unit must be able to disconnectreconnect fixed wired equipment up to volts ac volts dc Competency in this unit cannot be claimed until all prerequisites have been satisfied
Context of 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
Interdependent assessment	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 up to 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 provides information about the context in which the unit of competency is carried out. The variables and scope cater for different work requirements, work practices and knowledge between States, Territories and the Commonwealth, and between organisations and workplaces. The range statement relates to the unit as a whole and provides a focus for assessment. Text in italics in the performance criteria is explained here. The following variables may be present and may include, but are not limited to, the examples listed under the scope. All work is undertaken to relevant legislative requirements, where applicable
Variable	Scope
Equipment	As defined in the licensing requirements
Isolation refers to	Safe disconnection of all electrical power to equipment or equipment supply circuits via switching, circuit breakers or fuses etc. On circuits/equipment using up to 1000 volts a.c. or 1500 volts d.c. single or multi-phase supply
Test equipment	Voltmeters, multimeters, tong testers and a range of hand tools such as pliers, screwdrivers, sockets and spanners
Connect equipment	Refers to reconnection of existing equipment or the replacement on a 'like for like' basis with no alteration to existing fixed wiring
