โ Indicative tool only. All cables and protection must be verified by a licensed electrical engineer. Does not include ambient/grouping derating, short-circuit/fault current, earth-loop impedance or selectivity. See Compliance Check for details.
Add an EVDB group (e.g. per zone/level) with nested chargers, or add a standalone charger running direct to MSB with no EVDB.

โ INDICATIVE TOOL โ NOT A SUBSTITUTE FOR ENGINEERING REVIEW
This tool provides indicative sizing only. All cables and protection must be independently verified by a licensed electrical engineer. Calculations do NOT account for:
- Ambient ground or air temperature derating (AS/NZS 3008 Table 27)
- Grouping factor for circuits sharing conduit or tray (Tables 22-25)
- Installation method (in conduit, on tray, direct buried, etc.)
- Short-circuit / fault current ratings (Iหยฒt, MCCB breaking capacity)
- Earth-loop impedance and disconnection times
- Selectivity / discrimination between protective devices
