Guidance Information
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 outcomes 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 at Work Act 2015; 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 Connexis Infrastructure ITO
4The phrase in accordance with industry requirements is implicit in all outcomes 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.
6For the purposes of this unit standard all practical experience must be obtained on multicore power cables.
