Elements and Performance Criteria

  1. Prepare to select equipment
  2. Safety and relevant regulatory electrical installation requirements are identified and applied
  3. Arrange installation into circuits
  4. Circuits are arranged to comply with applicable technical industry standards and job specification requirements
  5. Earthing is arranged to comply with the multiple earthed neutral (MEN) system requirements
  6. Select cables, protection and switchgear
  7. Cable conductor sizes are selected to meet current-carrying capacity requirements and voltage-drop and fault-loop impedance limitations
  8. Protection methods and devices are selected to meet coordination requirements for overload and short circuit protection
  9. Switchgear and control gear are selected to meet current, voltage and ingress protection (IP) ratings and functional requirements

  11. Evidence is obtained that electrical equipment selected complies with safety requirements
  12. Document electrical installation
  13. Electrical installation arrangement and specifications for items are documented in accordance with workplace procedures and forwarded to appropriate person/s

Range Statement

Range is restricted to essential operating conditions and any other variables essential to the work environment.

Non-essential conditions may be found in the UEE Electrotechnology Training Package Companion Volume Implementation Guide.

Selecting and arranging low voltage (LV) electrical equipment must include at least two of the following types of special installations:

caravan parks

construction and demolition sites

marinas

medical treatment areas

moveable premises

shows and carnivals

Special LV electrical installations must include the following:

consumer mains

main earthing system and main switchboard

sub-mains

earthing system and distribution boards

final sub-circuits and requirements particular to the installation type
