The following apply to the performance of all elements of this unit standard:
a
All required equipment must be set up, started up, operated, and shut down in
accordance with company procedures.
b
All work practices must meet recognised codes of practice and documented
worksite health and safety procedures (where these exceed code) for personal,
product, and worksite health and safety, and must meet the obligations required
under the Health and Safety in Employment Act 1992.
c
All work practices must meet recognised codes of practice and documented
worksite environmental procedures (where these exceed code) for personal,
product, and worksite environmental matters, and must meet the obligations
required under the Resource Management Act 1991.
d
All work practices must meet documented worksite quality management
requirements. These include documentation of activities, events, and decisions.

Workplace practice means that the performance criteria are interpreted in
accordance with the technique of wiring installation used in the workplace of the
candidate being assessed. Practice may vary between workplaces because of the
potential variation of production trailerboat types particularly between aluminium and
FRC (fibre reinforced composite) trailer boats. For example earthing requirements
may vary significantly, because of the susceptibility to corrosion of aluminium.

Definitions:
AH – amp hours.
LED – light emitting diode.
Tinned – wire that is coated with tin.
Loom – a pre made arrangement of the wires into a organised fashion ready for
installation into the vessel.

Please note
Providers must be accredited by the Qualifications Authority, 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 the Qualifications Authority 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.
