Description
This unit involves the skills and knowledge required to verify compliance and functionality of a special low voltage (LV) electrical installation.It includes preparing for testing and visual inspection for verifying an electrical installation, and completing reporting and recommendations of finding.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. 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 to inspect and test an electrical installation
  • 1.1 Work health and safety (WHS)/occupational health and safety (OHS) measures for the site are identified, obtained and applied
  • 1.2 WHS/OHS risk control measures and procedures in preparation for the work are followed
  • 1.3 WHS/OHS hazards not previously identified are noted, risks assessed and risk control measures implemented
  • 1.4 Installation documentation and relevant industry standard are reviewed and applied
  • 1.5 Appropriate person/s is consulted to ensure the work is coordinated effectively with others
  • 1.6 Tools, equipment and testing devices needed to verify compliance are obtained in accordance with workplace procedures and checked for operation and safety
  • 1.7 Preparatory work is checked to ensure no damage has occurred in accordance with workplace procedures
2 Visually inspect the installation
  • 2.1 WHS/OHS risk control measures and procedures for carrying out the work are followed
  • 2.2 Need to inspect, test and measure live work is determined in accordance with WHS/OHS requirements and workplace procedures
  • 2.3 Circuits/machines/plant are checked and isolated in accordance with WHS/OHS requirements and workplace procedures
  • 2.4 Installed wiring is checked for suitability for the environments and protected from damage and overheating
  • 2.5 Cable conductor sizes acquired are inspected to meet current-carrying capacity requirements, voltage-drop and fault-loop impedance limitations in accordance with relevant industry standards
  • 2.6 Inspection protection methods and devices are validated to meet coordination requirements for overload and short circuit protection in accordance with relevant industry standards
  • 2.7 Switchgear and control gear are inspected, validated and appropriately rated to meet functional requirements in accordance with relevant industry standards
  • 2.8 Electrical equipment is checked for compliance with safety requirements in accordance with relevant industry standards
  • 2.9 Earthing system components are checked, located and conductors correctly sized in accordance with relevant industry standards
  • 2.10 Markings on switchboards are checked for accuracy and clarity in accordance with relevant industry standards
3 Conduct safety testing
  • 3.1 WHS/OHS risk control measures and procedures for carrying out the work are followed
  • 3.2 Need to test and measure live electrical work is conducted in accordance with WHS/OHS requirements and workplace procedures
  • 3.3 Circuits/machines/plant are checked and isolated in accordance with WHS/OHS requirements and workplace procedures
  • 3.4 Mandatory tests are conducted to verify earthing conductor resistance is sufficiently low; insulation resistance is sufficiently high; polarities are correct; circuit connections are correct; and tests are in accordance with relevant industry standards
  • 3.5 Inspection and testing are conducted to verify fault-loop impedance is sufficiently low and residual current device (RCD) operates as intended in accordance with job requirements and relevant industry standards
4 Report inspection and test findings
  • 4.1 WHS/OHS risk control work completion measures and workplace procedures are followed
  • 4.2 Worksite is cleaned and made safe in accordance with workplace procedures
  • 4.3 Non-compliance defects are identified and reported in accordance with workplace procedures
  • 4.4 Recommendations for rectifying defects are made in accordance with workplace procedures
  • 4.5 Mandatory documentation is completed in accordance with workplace procedures
