Operate 240 to 440 voltage alternating current electrical systems

Assessment tool

Version 1.0
Issue Date: May 2024


This unit involves the skills and knowledge required to operate a 240 to 440 volt (V) alternating current (AC) electrical system according to technical specifications and safe operating limits.

It includes preparing for operation, operating electrical systems, and checking and completing operations of electrical systems.

This unit applies to people working in the maritime industry in the capacity of:

Chief Engineer on vessels with inboard engines less than1500 kW within the exclusive economic zone (EEZ)

Second Engineer on vessels with inboard engines less than 3000 kW within the EEZ

Chief or Second Engineer on vessels with outboard engines with unlimited propulsion power within the EEZ

assistant under the direct supervision of the Chief Engineer

worker in the engine room of a vessel less than 80 metres in length with propulsion power less than 3000 kW.

Licensing/Regulatory Information

Legislative and regulatory requirements are applicable to this unit.

This unit is one of the requirements to obtain Australian Maritime Safety Authority (AMSA) certification as a Marine Engine Driver Grade 1 Near Coastal, as defined in the National Standard for Commercial Vessels (NSCV) Part D.

Note: Relevant state/territory training and qualification requirements must be fulfilled by any persons carrying out installation, maintenance and/or repair of electrical circuits or systems that are 50 V AC or above, or 120 V direct current (DC) or above.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

single and three phase alternating current (AC) power generation.

Assessors must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.

As a minimum, assessment must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Practical assessment must occur in a workplace, or realistic simulated workplace, under the normal range of workplace conditions.

Simulations and scenarios may be used where situations cannot be provided in the workplace or may occur only rarely, in particular for situations relating to emergency procedures and adverse weather conditions where assessment would be unsafe, impractical or may lead to environmental damage.

Resources for assessment must include access to:

a commercial vessel with inboard diesel propulsion power of greater than or equal to 375 kW or appropriate engine and auxiliary system ashore

applicable documentation, such as legislation, regulations, codes of practice, workplace procedures and operational manuals

tools, equipment, machinery, materials and personal protective equipment (PPE) currently used in industry.
