Used by TAFE


  • Fully complies with:

    • AS/NZS 3008.1.1:2009/Amdt 1:2011 - Selection of cables

    • AS/NZS 3000:2007/Amdt 2:2012 - Wiring Rules

  • Determine cable sizes and voltage drops according to installation conditions.

  • Use the Derating Wizard to apply appropriate de-rating factors.

  • Comply with earth fault loop impedance test requirements of AS 3000.

  • Calculate most economical (and compliant) cable sizes based on:

    • Current capacity; and/or

    • Voltage drop; and

    • Short-circuit performance

    • Earth fault loop impedance

  • User can specify their own cable sizes from 1mm2 to 630mm2.

  • Save results to file (.cbl) and Print reports with references to Standards.

  • Print reports directly to PDF.

  • Warning system - helps to avoid making errors.
