Application
This unit involves the skills and knowledge required to install/maintain rail signalling power supplies. It includes preparing and installing/maintaining rail signalling power supplies by working safely to installation/maintenance industry standards, matching equipment with that specified for location, terminating cables and connecting wiring compliance, functional testing, certifying and reporting. 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. |

Assessment Conditions
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 suitable simulated 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: a range of relevant exercises, case studies and/or other simulations relevant and appropriate materials, tools, facilities, equipment and personal protective equipment (PPE) currently used in industry resources that reflect current industry practices in relation to installing/maintaining rail signalling power supplies applicable documentation, including workplace procedures, equipment specifications, regulations, codes of practice and operation manuals. |
