Definitions
Industry practice – practice used and recommended by organisations involved in the
electrotechnology industry.
Switchboard – low-voltage switchgear and control gear assemblies, the rated voltage
of which does not exceed 1000 V a.c. at frequencies not exceeding 1000 Hz, or 1500
V d.c.
Wire electric switchboards – means to install and terminate cables and wires,
progressing from the point where mechanical assembly of the switchboard has been
completed.

Range
All activities are to be conducted in accordance with applicable specifications,
documented enterprise, legislative and/or regulatory requirements, and local bylaws
as appropriate. Activities must also meet the requirements of the above in terms of
personal, product, and work site safety.
Outcomes and evidence requirements
Outcome 1
Select cables, wires, and associated hardware for electric switchboards.
Evidence requirements
1.1
Cable and wire types are either selected to match the job specification, or
chosen to match the job requirements where they are not specified.
1.2
Voltage and current ratings of cables and wires are either selected to match the
job specification, or selected using standard tables to match the job
requirements where they are not specified.
1.3
Hardware associated with cabling is either selected to suit the job specification,
or chosen to meet the job requirements where they are not specified.
Range
hardware – ducting, trunking, wiring looms, cable ties, busbars.
Outcome 2
Install cables, wires, and associated hardware in electric switchboards.
Evidence requirements
2.1
Ducting and trunking are installed in accordance with specifications or industry
practice.
2.2
Cables and wires are run between termination points in accordance with
specification or industry practice.
2.3
Cables and wires are identified or labelled in accordance with specification or
industry practice.

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.
