Size active, neutral, and earth cables using AS/NZS 3008 (2025). The guide covers current capacity, voltage drop, and short-circuit calculations with examples.
The cable distribution box should be installed near the load center to minimize the length of the cable and reduce power loss. For example, placing a box near a cluster of high-power
Calculate electrical cable size based on current, voltage drop, and installation method. NEC and IEC compliant cable sizing tool.
Number of cables per box = cable length per box / actual average cable length. Number of cable boxes required = total number of information points / number of cables per box.
Use our Cable Sizing Calculator when designing electrical installations. Enter load current, ambient temperature, grouping, and cable length to get recommended cable size with
Use the cable sizing calculator to accurately size copper or aluminum cables for any project and avoid costly oversizing.
