·         equipment, accessories and components
13.   inspect and test, as appropriate and in accordance with recognised industry methods and practices, the repair and/or the replacement:
·         electrical cables, conductors and/or wiring system
·         equipment, accessories and components
14.  provide clear and accurate information to relevant people about the Solar PV and EESS system and equipment in terms of:
·         hand over to the customer/client
·         any variations to the original system and/or its equipment
·         customer/client acceptance of the completed work in
·         accordance with organisational procedures
·         relevant documentation being completed and recorded in the appropriate systems in accordance with organisational procedures

1.    the operation, applications, advantages and limitations of different Solar PV and EESS systems
2.    how to obtain clearly and detailed information about the reported fault(s) and any components which require to be replaced from:
·         relevant sources of information
·         relevant documentation
3.    the organisational procedures and industry practices when undertaking the processes for the identification and rectification of faults when:
·         advising the relevant people about the potential of any disruption and consequences
·         confirming the programme of work with the relevant people 
·         ensuring the coordination of site services and the activities of other trades affected
4.    how to determine and obtain the resources required, as relevant, to undertake:
·         the identification and location of the fault(s)
·         the rectification of the fault(s)
5.    how to select the instruments to be used
6.    how to confirm that the instruments are fit for purpose and have a current calibration certificate
7.    the correct procedures for safe isolation for AC and DC systems
8.    the techniques to identify, locate, diagnose and rectify faults
9.    how to repair, remove and replace in accordance with industry practices:
·         electrical cables, conductors and/or wiring system
