This unit standard is intended for the training and assessment
of people engaged in the manufacture of electric switchboards
and covers the knowledge and skill required to assemble
switchboards from basic switchgear and control gear
components and drawing specifications. It excludes the
electrical wiring and the fabrication of busbars.
People credited with this unit standard are able to:
–
prepare components for assembly of electric
switchboards;
–
assemble switchboard enclosures;
–
fit switchgear components;

Definitions
Assemble – the mechanical assembly of the switchboard, including the mounting of
all switchgear and control gear components and cable ducts, but excludes the
installation and termination of cables and wires.
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.

Range
a All activities are to be conducted in accordance with applicable specifications,
documented enterprise, legislative and/or regulatory requirements, and local
bylaws. Activities must also meet the requirements of the above in terms of
personal, product, and work site safety.
b This unit standard does not cover switchboard electrical wiring or the fabrication of
busbars. These are covered in unit standards 14973, Wire electric switchboards
and 14974, Fabricate and install busbars in electric switchboards.

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.
