List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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 |

adding resistors in series and parallel, and calculating current
connecting to shore power
isolating electrical circuits
maintaining records of operating and maintaining electrical systems, and any related safety incidents
monitoring and evaluating performance of electrical systems
performing switchboard operations including the monitoring of electrical supply and procedures for paralleling generators
reading and interpreting:

Assessors must satisfy National Vocational Education and Training Regulator (NVR)/Australian Quality Training Framework (AQTF) assessor requirements.
Assessment must occur in workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated workplace operational situations that reflect workplace conditions.
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.
Resources for assessment must include access to:
tools, equipment, machinery, materials and personal protective equipment currently used in industry
applicable documentation such as legislation, regulations, codes of practice, workplace procedures and operational manuals
range of relevant exercises, case studies and/or simulations.
