Overview

This standard identifies the competences you need to set to work, test and trial marine electrical rotating machines and domestic equipment, in accordance with approved procedures.  You will be required to use appropriate drawings, specifications and test documentation to set up, test and trial the various types of equipment.  You will be expected to use the specified/appropriate techniques to carry out the appropriate setting up, testing and trialling procedures.  The equipment to be set up, tested and trialled will include single and three-phase motors of various power ratings, their starters and control/protection devices, as fitted to pumps, compressors, fans, winches and electrical components of domestic/auxiliary equipment such as heaters, refrigerators, dishwashers and laundry support facilities.

The tests to be carried out will include protective over-voltage and current limiters, resistance values, load current and earth checks.  You will be expected to review the outcome of the tests, compare the results with appropriate standards, determine the action required and to record and report the results in the appropriate format.

Your responsibilities will require you to comply with organisational policy and procedures for the setting up, testing and trialling activities undertaken and to report any problems with these activities that you cannot personally resolve, or are outside your permitted authority, to the relevant people.  You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out. **     

Your underpinning knowledge will provide a good understanding of your work and will provide an informed approach to applying appropriate setting up, testing and trialling techniques and procedures on marine electrical rotating machinery and domestic equipment.  You will understand the function of the electrical machine and equipment being set to work and tested and its application and will know about the test equipment and methods, in adequate depth to provide a sound basis for carrying out the activities, correcting faults and ensuring that the work output is to the required specification.

You will understand the safety precautions required when carrying out the set to work, testing and trialling operations, especially those for isolating the equipment and for taking the necessary safeguards to protect yourself against direct and indirect electric shock.  You will be required to demonstrate safe and (in the case of food associated equipment) hygienic and working practices throughout and will understand the responsibility you owe to yourself and others in the workplace.
