Special notes
1 Assessment against this unit standard is to be carried out within the context of an organisation operating under a current, valid Rail Licence issued in accordance with the provisions of the Railways Act 2005. The organisation’s operating rules, codes, and instructions, referred to in this unit standard, are those the organisation has in place to meet the requirements of the Rail Licence.
2 Candidates must first hold the appropriate licence, qualification, and/or certification for any electrical work undertaken in the course of assessment for this unit standard.
Examples include: electrical service technician (A, B), registered electrician.
Additionally, candidates must have undertaken training in, and hold the appropriate licence/certification for, any activity that requires pole-top work. These conditions will be in accordance with organisational procedures and/or regulatory requirements that govern live electrical work and working safely at heights.
