Release 1. This is the first release of this unit of competency in the UEE Electrotechnology Training Package.

This unit involves the skills and knowledge required to repair of signalling power cables and multi-core signalling control cables up to 50 cores.

It includes following workplace procedures, selecting and using appropriate cable joining methods, testing continuity and insulation resistance of repaired cable cores, and reporting repair activities.

Persons achieving competence in this unit will need to fulfil the applicable state/territory legislated rail safety requirements and to comply with relevant codes of practice, rules and/or guidelines.

No other licensing, legislative or certification requirements apply to this unit at the time of publication.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.

Range is restricted to essential operating conditions and any other variables essential to the work environment.

Non-essential conditions may be found in the UEE Electrotechnology Training Package Companion Volume Implementation Guide.

Performing signalling cable repairs must include the following:

• repairing at least one signalling power cable relevant to a particular rail transport operator
• repairing at least one signalling multi-core control cable, six cores or greater, relevant to a particular rail transport operator
• repairing signalling cables using at least one approved jointing kit

This unit replaces and is equivalent to UEENEEN121A Repair rail signalling power and control cables.

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must occur in suitable workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated suitable workplace operational situations that replicate workplace conditions.

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.

Resources for assessment must include access to:
