Calculators that use these parts
- Cable sizeFind the smallest cable size that passes each check.
- Voltage dropCalculate voltage drop on a cable run and check the limit.
- Loop impedanceCheck earth fault loop impedance against the maximum Zs.
- Fault ratingCheck that a conductor can withstand the fault current.
- Conduit fillCheck that a cable bundle fits in a conduit.
- Voltage riseCalculate voltage rise for embedded generation or PV.
Worked examples
- Conduit size for 35 mm cable in a submainFour 35 mm² singles in a 50 mm conduit fill 19.48 % of the internal area, and the AmpSize engine still recommends a 40 mm conduit for this submain.
- Builder's pole: supply, RCDs and cord lengthsA builder's pole for a house build, worked to AS/NZS 3012:2019. The supply it may take, the 30 mA RCDs, the Table 1 cord lengths and the test intervals.
- Homeowner shed supply voltage drop over 60 mA 20 A single‑phase supply running 60 m to a shed on 6 mm² copper, with the drop, the percentage and the maximum length the AmpSize voltage drop engine returns.
