Description
This unit involves the skills and knowledge required to operate a 240 to 440 voltage alternating current (AC) electrical system according to technical specifications and safe operating limits.
Notes
Elements and Performance Criteria
1 Prepare for operation
- 1.1 Risks to self, others and the environment are identified according to organisational procedures
- 1.2 Routine pre-operational checks of electrical systems are completed prior to use according to manufacturer specifications and organisational procedures
2 Operate electrical systems
- 2.1 Suitable personal protective equipment is selected and used according to organisational procedures
- 2.2 Electrical systems are operated in a safe and controlled manner
- 2.3 Performance of direct current (DC) and AC electrical systems is monitored
- 2.4 AC electrical demand is monitored and additional generators are paralleled or disconnected as required
- 2.5 Ship to shore electrical supply is connected and disconnected when required following established practices and organisational procedures
- 2.6 Faults or malfunctions are identified and reported according to organisational procedures
- 2.7 Faults or malfunctions are rectified and corrective actions are taken and recorded according to organisational procedures
- 2.8 Procedures to be undertaken in emergencies are recognised and implemented
3 Complete operations and check electrical systems
- 3.1 Shut-down procedures are conducted according to manufacturer instructions and organisational procedures
- 3.2 Operational records are completed according to organisational procedures

Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the Elements, Performance Criteria, Required Skills, Required Knowledge and include:
attention to appropriate level of detail in recordkeeping
being aware of own ability and limits to rectify irregularities and faults.
Context of and specific resources for assessment
Performance is demonstrated consistently over time and in a suitable range of contexts.
Resources for assessment include access to:
industry-approved marine operations site where operating 240 to 440 voltage AC electrical systems can be conducted
tools, equipment and personal protective equipment currently used in industry
relevant regulatory and equipment documentation that impacts on work activities
range of relevant exercises, case studies and/or other simulated practical and knowledge assessments
appropriate range of relevant operational situations in the workplace.
In both real and simulated environments, access is required to:
relevant and appropriate materials and equipment
applicable documentation including workplace procedures, regulations, codes of practice and operation manuals.
Method of assessment
Practical assessment must occur in an:
appropriately simulated workplace environment and/or
appropriate range of situations in the workplace.
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate to this unit:
direct observation of the candidate operating 240 to 440 voltage AC electrical systems
direct observation of the candidate applying relevant WHS/OHS requirements and work practices.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.
In all cases where practical assessment is used it should be combined with targeted questioning to assess Required Knowledge.
Assessment processes and techniques must be appropriate to the language and literacy requirements of the work being performed and the capacity of the candidate.
