Unit Of competency

Modification History

Release 1. New unit of competency.

Application

This unit involves the skills and knowledge required to complete basic maintenance of electrical systems.

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

Relevant state/territory electrical licensing requirements apply to persons carrying out installation, maintenance and/or repair of electrical circuits or systems that are 50 V alternating current (AC) or above, or 120 V direct current (DC) or above, on a vessel.

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:

  • carrying out simple maintenance of electrical systems
  • implementing safe and environmentally responsible work practices
  • reading and interpreting system specifications.

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:

  • battery:
  • charging systems
  • maintenance
  • types and associated hazards
  • connecting batteries in series and parallel
  • connection to shore power
  • earth indicating devices
  • electrical distribution systems
