Description
This unit involves the skills and knowledge required to identify, shut down and restart systems with alternate supplies.It includes identifying the system configuration, working safely with electricity generation systems and inverters, identifying hazards and controlling the associated risks, isolation and testing for de-energisation, reinstating the system after isolation, and completing relevant documentation.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

  • 1.4 Tools, equipment and circuit testing devices are obtained and checked for correct operation and safety in accordance with workplace procedures
  • 1.5 Work supervisor is consulted to ensure work is coordinated effectively with others
2 Identify and isolate alternate supplies
  • 2.1 Labelling indicating generation system/s connected on site is located, interpreted and checked against electrical diagrams
  • 2.2 Switchboard, circuits and known supply are identified
  • 2.3 Site procedures for isolation and shutdown are obtained and interpreted
  • 2.4 Circuit to be isolated is identified and tested
  • 2.5 Shutdown procedures are completed in accordance with industry standards and workplace procedures
  • 2.6 Isolation of energy sources is completed and proved in accordance with workplace procedures, industry standards and regulatory requirements
  • 2.7 Systems are inspected and tested for compliance with industry and regulatory standards
  • 2.8 Battery storage system integrity is checked in accordance with industry standards and regulatory requirements
  • 2.9 System is re-instated after isolation
3 Complete work and document records
