Application
This unit involves the skills and knowledge required to attach flexible cords, cables and plugs, including trailing and feeder cables, to high voltage (HV) electrical equipment connected to a supply exceeding 1,000 volts (V) alternating current (a.c). or 1,500 volts (V) direct current (d.c.). It includes working safely; identifying plug configurations; selecting and using inspecting, testing and measuring devices; terminating and connecting HV flexible cables, plugs and conductors; safety testing and reporting. 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 V a.c. or 120 V 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. |
