1. Prepare to inspect and test an electrical installation.
1.1 WHS/OH&S procedures for a given work area are identified, obtained and understood.
1.2 Established WHS/OH&S risk control measures and procedures in preparation for the work are followed.
1.3 Safety hazards, which have not previously been identified, are noted and established risk control measures are implemented.
1.4 Documentation, or deemed to comply standard on which installation is based, is reviewed and understood.
1.5 Appropriate personnel are consulted to ensure the work is coordinated effectively with others involved on the work site.
1.6 Tools, equipment and testing devices needed to verify compliance are obtained in accordance with established
procedures and checked for correct operation and safety.
1.7 Preparatory work is checked to ensure no damage has occurred and complies with requirements.
2. Visually inspect and conduct safety testing on the installation.
2.1 WHS/OH&S risk control measures and procedures for carrying out the work are followed.
2.2 The need to test or measure live is determined in strict accordance with WHS/OH&S requirements and when necessary conducted within established safety procedures.
2.3 Circuits/machines/plant are checked as being isolated where necessary in strict accordance WHS/OH&S requirements and procedures.
2.4 Wiring is checked for suitability for the environments in which they are installed and suitably protected from damage or
overheating.
2.5 Cable conductor sizes are confirmed as meeting current-carrying capacity requirements and voltage-drop and fault-loop impedance limitations.
2.6 Protection methods and devices are validated as meeting coordination requirements for overload and short-circuit protection.
2.7 Switchgear and control gear is validated as being appropriately rated and meeting functional requirements.
2.8 Evidence that electrical equipment complies with safety requirements is cited.
2.9 Earthing system components are checked that they are correctly located and conductors correctly sized.
2.10 Marking on switchboards are checked for accuracy and clarity and comply with requirements.
2.11 Mandatory tests are conducted to verify that: earthing conductor resistance is sufficiently low; insulation resistance is sufficiently high; all polarities are correct; and circuit connections are correct as per AS/NZS 3000:2007 Electrical installations known as the Australian/New Zealand Wiring Rules).
2.12 Testing is conducted to verify that: fault-loop impedance is sufficiently low and residual current devices operate as intended as per AS/NZS 3000:2007 Electrical installations (known as the Australian/New Zealand Wiring Rules)”as amended”.
3. Report inspection and test findings.
3.1 WHS/OH&S risk control work completion measures and procedures are followed.
3.2 Work site is cleaned and made safe in accordance with established procedures.
3.3 Non-compliance defects are identified and reported in accordance with established procedures.
3.4 Recommendations for rectifying defects are made in accordance with established procedures.
3.5 Mandatory documentation is completed in accordance with established procedures.
