This page explains how to record the results of mandatory safety tests for the CCEW form and ensure compliance with NSW regulations. Accurate testing and reporting are critical for ensuring the safety and compliance of your work.

​
Test date

Select the date the tests were performed. This is a required field. You can select the date from the calendar, or use the “Yesterday” or “Today” buttons for quick selection. The test date must be on or before the date of certification.
Always perform all required tests before certifying the installation. The test date should reflect the actual date of testing.

Test requirements

Check the box next to each test that was performed. You can also click the “Check All” button to select all the tests at once. Below is an explanation of each test:
  • Earthing system integrity: Verifies that the installation’s main earthing conductor is continuous and correctly connected. A reliable earth connection is essential for safety devices to operate correctly during a fault, preventing electric shock.
  • Residual current device operational: Confirms that all installed Residual Current Devices (RCDs) or safety switches trip within the required time when tested. This is a life-saving test that ensures protection against electric shock.
  • Insulation resistance (MΩ): Measures the quality of the insulation surrounding the electrical conductors. A high insulation resistance value (typically >1 MΩ) indicates that the insulation is in good condition and there is no current leakage, preventing potential short circuits and shocks.
  • Visual check suitability of installation: A thorough visual inspection to confirm that all equipment is installed correctly, is suitable for the environment, is not damaged, and meets all requirements of the Wiring Rules (AS/NZS 3000).
  • Polarity: Ensures that the active, neutral, and earth conductors are correctly connected at all points in the installation, including socket outlets and lighting points. Incorrect polarity can be extremely dangerous.
  • Stand-Alone system complies with AS4509: If the work involves an off-grid or stand-alone power system, this confirms it complies with the specific requirements of AS/NZS 4509 for such systems.
  • Correct current connections: Verifies that all conductors are correctly and securely terminated in switchboards and equipment, ensuring reliable operation and preventing potential fire hazards from loose connections.
  • Fault loop impedance (if necessary): Measures the impedance of the path a fault current would take to return to the source. A low impedance is required to ensure that enough current flows during a fault to trip circuit breakers or blow fuses within the required time. This test is critical for confirming the effectiveness of protective devices.
All tests must be performed in accordance with AS/NZS 3000 and other relevant standards.
Test results are validated to ensure they meet NSW compliance requirements and provide a record for future reference.
