Explanatory notes
1
This unit standard is intended for, but not restricted to, workplace assessment. The
range statements within the unit standard can be applied according to enterprise
specific equipment, procedures and processes.
2
Safety 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
assessed as not yet competent.
3
Performance 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,
the Resource Management Act 1991, and their subsequent amendments, electricity
supply industry codes of practice and documented enterprise procedures. These
include the latest version of, Safety Manual – Electricity Industry (SM-EI) Wellington:
Electricity Engineers’ Association.

The phrase in accordance with industry requirements is implicit in all outcomes and
evidence requirements in this unit standard.

Definitions
Industry requirements include 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.
6
This unit standard is intended for use in the assessment of cable jointers, and all
terminology and workplace assessment should be related to that sector of the
industry.
7
This unit standard excludes tough plastic sheath (TPS) type cables.
8
The observance of special safety requirements associated with this type of jointing is
critical to assessment against this unit standard. When working on live components
and live jointing the selection and use of hand tools is to comply with IEC 60900:2012
Live working – Hand tools for use up to 1000 V a.c. and 1500 V d.c.
9
HV is defined as ‘high voltage’ and includes voltages from 22kV up to and including
33kV.
10
Assessment of practical skills against the outcomes in this unit 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.
