Definitions
Current regulations and standards – refers to the requirements of the above
legislation and standards, applied to the context in which the term is used.
Electrical technicians and service persons – for the purposes of this unit standard
means, people who hold or who are working towards electrical registration as an
Electrical Service Technician or Electrical Appliance Serviceperson (endorsed to
disconnect and connect).
Fixed wired – the connection of an appliance via a permanent connection unit, rather
than by means of a plug and socket.
Industry practice – those practices which competent practitioners within the industry,
recognise as current industry best practice.
5
Range
Evidence of three different types of single-phase fixed-wired appliances is required.
Outcomes and evidence requirements
Outcome 1
Isolate and disconnect fixed wired single-phase appliances.
Evidence requirements
1.1
Testing and inspection establishes supply voltage, and, where appropriate,
leads to identification of motor rotation and details of connections are recorded.
1.2
Circuit is isolated and tagged according to industry practice.
1.3
Testing verifies isolation of all live conductors according to industry practice.
1.4
Appliance or equipment is disconnected from the supply conductors or
terminals and any exposed wiring made safe according to industry practice.
1.5
Details of connections are recorded to facilitate later reconnection.

Outcome 2
Test and reconnect fixed wired single-phase appliances.
Evidence requirements
2.1
Testing and inspection confirm isolation of supply conductors or terminals and
presence of tags.
2.2
Testing and inspection of the appliance or equipment confirm that requirements
of current regulations and standards have been met, and that the appliance or
equipment is safe for reconnection to the supply conductors or terminals.
testing – protective earthing continuity, insulation resistance,
polarity.
Range
2.3
Appliance or equipment is reconnected to the supply conductors or terminals
according to industry practice and current regulations and standards.
reconnection includes – termination of conductors; confirming
motor rotation, adjusting motor rotation when required.
Range
2.4
Reconnection includes restoration of supply and removal of warning tags
according to 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

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.
