Outcomes and evidence requirements
Outcome 1
Demonstrate knowledge of cables used in automotive wiring circuits.
Evidence requirements
1.1
Cable types and sizes, their means of identification, and a common use for
each type are determined.
Range
1.2
number of strands, strand diameter, current capacity, colour
coding;
types – shielded, unshielded, ribbon, single and multicore,
braided.
Current ratings for cables used singly, and when used in a harness, are

Range
personal safety; safety of others; equipment, vehicle, and machine
safety.
2.2
Suitable tools and equipment are selected and used to enable repairs to be
carried out.
2.3
Damaged wires are repaired to restore electrical conductivity, mechanical
strength, and neat appearance.
Range
single wires and wiring harnesses.
2.4

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.
