PURPOSE OF THE UNIT STANDARD 
This unit standard will be useful to people who are required to carry out a detailed inspection on low voltage switchgear.

People credited with this unit standard are able to
  • Explain the requirements pertaining to the inspection of low voltage switchgear
  • Prepare to inspect the switchgear
  • Inspect the switchgear
  • Test the switchgear and prepare for operation and / or production 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    The credit calculation is based on the assumption that learners are already competent in terms of the following outcomes or areas of learning when starting to learn towards this unit standard
    The ability to:
  • Use hand held test instruments
  • Use relevant hand tools
  • Read and interpret electrical diagrams

    Knowledge of:
  • The dangers related to electrocution
  • The treatment for electrical shock 
    		•

    UNIT STANDARD RANGE 
    The following scope and context applies to the whole unit standard:
  • Electrical switchgear operating at a voltage not exceeding a1000 volts
  • Electrical motor control panels
  • Electrical machine panels
  • Section switchgear in underground coal mines
