Special notes

1This unit standard is intended for, but not restricted to, workplace assessment.

2Safety of personnel and plant must be a priority throughout the assessment. If the safety requirements are not met the assessment must stop.

3Performance and work practices in relation to the elements and performance criteria must comply with all current legislation, especially the Electricity Amendment Act 2006, and any regulations and codes of practice recognised under that statute; the Health and Safety in Employment Act 1992; and the Resource Management Act 1991. Electricity supply industry codes of practice and documented industry procedures include the Safety Manual – Electricity Industry (SM-EI)Wellington: Electricity Engineers’ Association. A full list of current legislation and industry codes is available from the Electricity Supply Industry Training Organisation, PO Box 1245, Waikato Mail Centre, Hamilton 3240.

4The phrase in accordance with industry requirements is implicit in all elements and performance criteria in this unit standard.

5Industry requirementsinclude all asset owner requirements; manufacturers’ specifications; and enterprise requirements which cover the documented workplace policies, procedures, specifications, business, and quality management requirements relevant to the workplace in which assessment is carried out.

6Asset ownerrefers to the owner of an electricity supply network that takes its point of supply from Transpower NZ and delivers electricity to industrial, commercial, and residential customers.

7HV is defined as high voltage and includes voltages at 66kV and above.

8For the purposes of this unit standard all practical experience must be obtained on multicore power cables.

Please note

Providers must be accredited by NZQA, or an inter-institutional body with delegated authority for quality assurance, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.

Industry Training Organisations must be accredited by NZQA before they can register credits from assessment against unit standards.

Accredited providers and Industry Training Organisations assessing against unit standards must engage with the moderation system that applies to those standards.

Accreditation requirements and an outline of the moderation system that applies to this standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The AMAP also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
