Explanatory notes
1This unit standard is intended forworkplace assessment. The range statements within the unit standard can be applied according to enterprise specific equipment, procedures and processes.
2Safety of personnel and plant must be a priority throughout the assessment. If the safety requirements are not met the assessment must stop and the candidate will be marked net yet competent.
3Performance and work practices in relation to the outcomes and evidence requirements must comply with all current legislation, especially the Electricity Act 1992 and any subsequent amendments, and any regulations, codes of practice recognised under that statute, Health and Safety in Employment Act 1992, Approved Code of Practice – Power-Operated Elevating Work Platforms, the Resource Management Act 1991, and their subsequent amendments, electricity supply industry codes of practice and documented enterprise procedures. These include, Safety Manual – Electricity Industry (SM-EI) (2004) Wellington: Electricity Engineers’ Association.

4The phrase in accordance with industry requirements is implicit in all outcomes and evidence requirements in this unit standard.
5Definitions
Industryrequirementsinclude 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.
Asset owner refers 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.
Asset owner standards are the approved documented work site methods for carrying out work on an electrical supply network to the standard required by the asset owner.
6This unit standard is intended for the assessment of Distribution and Transmission Line Mechanics and all terminology and workplace assessment should be related to that sector of the industry.
7LV is defined as low voltage and includes voltages up to and including 1000 volts AC.
8Assessment of practical skills against the outcomes in this standard requires three practical observations from three different workplace activities.

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMR). The CMR 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.
