In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
A learner credited with this unit standard will be able to work live on 3kV DC OHTE or to clearance from exposed "live" high-voltage electrical equipment (3kV DC, 25 kV and 50kV AC OHTE and all transmission lines and associated equipment), thus contributing to the safety of personnel and the safe running of electric trains, as well as ensuring the continuity of power supply in the rail sector. 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
It is assumed that learners are competent in the following:
  • Mathematical Literacy at NQF Level 3.
  • Communication at NQF Level 3. 
    		•

    UNIT STANDARD RANGE 
    The level assigned to this standard is appropriate, because performance must be carried out:
  • Under different weather conditions.
  • During day and night time.
  • Within a specific operational time-span to minimise delays.
  • In different yard layouts/stations/sidings/sections.

    This unit standard is applicable to authorised persons to work live on 3kV DC OHTE or to clearance from exposed "live" high-voltage electrical equipment (3kV DC, 25 kV and 50kV AC OHTE and all transmission lines and associated equipment). 
    		•

    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
  • Anyone assessing or moderating a learner against this unit standard must be trained, qualified, certified and re-certified as an assessor/moderator in the OHTE/Substation division in accordance with the specific validation regulations relevant to the specific unit standard and registered with the relevant ETQA.
  • Any institution offering learning that will enable the achievement of this Qualification must be accredited as a provider with the relevant ETQA body or has a Memorandum of Understanding with a relevant ETQA.
  • The relevant ETQA body will oversee assessment and moderation of assessment or by an ETQA that has a Memorandum of Understanding with the relevant ETQA, according to the ETQA policies and guidelines for assessment and moderation.
  • Moderation must include both internal and external moderation of assessment at exit points of the Qualification, unless ETQA policies specify otherwise. Moderation should also encompass achievement of the competence described both in individual Unit Standards as well as the integrated competence described in the Qualification. 
    		•

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
