Evidence requirements 1.1 Type of cable is identified by sight in accordance with industry practice. Range flexible cords and cables – flat-section (Tru-rip), circular construction; polyvinyl chloride (PVC), tough plastic-sheathed (TPS), rubber sheathed; cables for fixed wiring – tough plastic-sheathed (TPS), conduit wire, neutral-screened or co-axial cable, cross-linked polyethylene (XLPE), steel-wire armoured (SWA), control wire, solid aluminium, stranded aluminium, telecommunications cable (extra low voltage). 1.2 Cable conductor size is determined for an assortment of common flexible cords and fixed wiring cables by sight, comparison with known cables, by interpretation of markings on cable or cable drum, or by measurement. 1.3 The characteristics unique to each type of cable are stated and a typical application given according to industry practice. Range 1.4 flexible cords and cables – flat-section (Tru-rip), circular construction; polyvinyl chloride (PVC), tough plastic-sheathed (TPS), rubber sheathed; evidence of two required; cables for fixed wiring – tough plastic-sheathed (TPS), conduit wire, neutral-screened (co-axial) cable, cross-linked polyethylene (XLPE), steel-wire armoured (SWA); evidence of two required; electrical cables – control cable, cross-linked polyethylene (XLPE), flex, neutral screen, solid aluminium, steel wire armoured, stranded aluminium, telecommunications cable (extra low voltage), tough plastic-sheathed (TPS); evidence of two required. Restrictions on the use of Tru-rip and other single insulation types of flexible cords are stated according to current regulations and standards.

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.
