an electricity confined space
Level
4
Purpose
Credits
10
People credited with this unit standard are able to: plan and
joint a live underground network LV cable as part of a team;
plan and carry out a transition joint between two HV service
cables on a distribution network as a member of a team; plan
and carry out identification and earthing of cables and
equipment within a work area; obtain a permit for working on
de-energising LV and HV electric underground cables; and
carry out rescue of a victim from an electricity confined space
as a member of a team.

Definitions
Industry requirements include all asset owner requirements; manufacturers’
specifications; and enterprise requirements which cover the documented workplace
policies, procedures, specifications, business, and quality management requirements
relevant to the workplace in which assessment is carried out.
Asset owner refers to the owner of an electricity supply network that takes its point of
supply from Transpower NZ, and delivers electricity to industrial, commercial and
residential customers.

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
