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 elements and performance criteria must comply with all current legislation, especially the Electricity Act 1992, 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.
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.
7The observance of special safety requirements associated with this type of termination shall be critical to assessment against this unit standard. When working on live components and live terminations the selection and use of hand tools is to comply with IEC 60900:2004 Live working – Hand tools for use up to 1000 V a.c. and 1500 V d.c.
8LV is defined as ‘low voltage’ and includes voltages up to and including 1000 volts AC.
