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’s specifications and regulatory requirements

connecting conductors to equipment and fasten/seal cables/wires/conduits using appropriate procedures and tools to relevant specifications and regulatory requirements

inspecting and testing terminated cables to ensure they comply with continuity and insulation resistance requirements and are safely intended for use

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 providing first aid, including contacting the appropriate medical and rescue authorities

recording details of first aid given.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

relevant regulatory requirements

characteristics of the circuit and the equipment

point(s) of isolation for the fixed wired equipment and reasons for selecting the particular isolation point(s) 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, techniques, tools and equipment to be used for:

determining and recording equipment characteristics

isolating the fixed wired equipment and proving electrical isolation

labelling conductors and recording conductor layout

disconnecting conductors

terminating disconnected cables/connections

checking circuits for safe isolation

terminating conductors and checking connections

connecting the conductors to the equipment

fastening and seal the cables, wires and conduits

removing lock-off equipment and signage

checking the operation of the equipment and circuits

checking and testing the compliance of the equipment with specifications

potential dangers/risks associated with work

recognised procedures for the movement and treatment of the injured person, including high voltage (HV) rescue, clearing of airways, care of spinal injuries, treatment of cuts/lesions, burns/scalds and treatment of shock

appropriate local medical and rescue services

procedures for incident reporting.

Assessment Conditions

Assessors must:

have vocational competency in disconnecting/reconnecting fixed wired equipment over 1000 volts a.c./1500 volts d.c. at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires

Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
