Description
This unit involves the skills and knowledge required to select, arrange and terminate circuits, control and protection devices and systems for electrical installations operating at low voltage (LV).It includes protection of persons and property, correct functioning, ensuring compatibility with the supply, arranging installation into circuits, selecting and arranging switchgear/control gear and protective devices to meet compliance requirements, and documenting arrangement decisions.The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 volt (V) alternating current (a.c.) or 120 V direct current (d.c.).Competency development activities in this unit are subject to regulations directly related to licensing. Where a licence or permit to practice is not held, a relevant contract of training, such as an Australian Apprenticeship, may be required.Additional and/or other conditions may apply in some jurisdictions subject to regulations related to electrical work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations.
Notes
Elements and Performance Criteria
1 Prepare electrical circuits, control and protection installation
  • 1.1 The extent and nature of the electrical installation is determined from job specifications
  • 1.2 Hazards are identified, risks are assessed and control measures are implemented
  • 1.3 Load requirements for individual current-using equipment is determined from job specifications and/or consultation with appropriate persons
2 Arrange electrical circuits, control and protection
  • 2.1 Circuits, control and protective devices are arranged to ensure safe and functional operation of the installation and to comply with relevant industry technical standards and job specification requirements
  • 2.2 Earthing is arranged and terminated to comply with the multiple earthed neutral (MEN) system requirements
  • 2.3 Protective devices are selected to meet the required switching and tripping currents coordination and discrimination for overload and short circuit protection in accordance with relevant industry technical standards
  • 2.4 Residual current devices (RCDs) are selected to meet the required circuit switching and tripping currents, in accordance with relevant industry technical standards
  • 2.5 Switchgear/control gear is selected to meet current and voltage requirements and confirmed suitable for environmental conditions (ingress protection (IP) ratings) and functional requirements
  • 2.6 Switchboards are arranged to accommodate control and protective devices, links, safety services and other distributor equipment in accordance with relevant industry technical standards
3 Document electrical installation circuits, control and protection arrangements
  • 3.1 Evidence is obtained from manufacturer/suppliers that electrical equipment selected complies with safety requirements in accordance with workplace procedures
  • 3.2 Device selection/s rationale and calculations are documented in accordance with workplace procedures
  • 3.3 Electrical installation and specifications for selected items are documented in accordance with workplace procedures and forwarded to appropriate person/s
