Unit Of competency

Modification History

Release 1. New unit of competency.

Application

This unit involves the skills and knowledge required to operate, test and maintain extra low and low voltage electrical systems and equipment.

This unit applies to engine workers in the maritime industry working as a Marine Engine Driver Grade 3 Near Coastal on vessels up to 500 kW or as a Marine Engine Driver Grade 2 Near Coastal on vessels up to 750 kW or as a Marine Engine Driver Grade 1 Near Coastal on vessels up to 1500 kW.

WARNING: Relevant state/territory training and qualification requirements need to be fulfilled by any persons carrying out installation, maintenance and/or repair of refrigeration equipment especially with regard to preventing the escape of refrigerants into the atmosphere and to electrical work.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria on at least one occasion and include:

  • applying safety requirements throughout the work sequence including the use of personal protective equipment
  • completing all work to specification
  • ensuring correct requirements and details of basic maintenance of electrical systems and equipment are available
  • implementing safe and environmentally responsible work practices in testing and maintenance activities
  • initiating timely action in response to defects or damage
  • locating, interpreting and applying manufacturer specifications for electrical systems and equipment
  • operating direct current (DC) systems and conducting operator preventive maintenance according to manufacturer recommendations, regulations and vessel operating procedures to ensure safe operation
  • operating electrical systems according to manufacturer recommendations, regulations and vessel operating procedures to ensure safe operation
  • recognising electrical system faults and where necessary taking steps to make them immediately safe
  • selecting and using appropriate processes, tools and equipment.

Knowledge Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

  • basic care and fault recognition of electrical systems and equipment
  • batteries:
  • care and maintenance
  • hazards
  • types
  • charging systems:
  • alarms/indicators
  • regulators
  • connecting batteries
  • DC systems not exceeding 32 V DC
  • electrical systems:
  • above 32 V DC and up to 415 V alternating current (AC)
  • fault identification, location and safety implications
  • personal safety
  • protective devices on switchboards
  • relevant state/territory training and qualification requirements for carrying out installation, maintenance and/or repair of refrigeration equipment especially with regard to preventing the escape of refrigerants into the atmosphere and to electrical work
