Electrical calculations.
On site. Offline. Cited.
Fast, offline electrical calculations to the AS/NZS 3000 Wiring Rules — cable size, voltage drop and more, every answer cited, with an on-device assistant.
Built for sparkies on the tools
Large, glove-friendly controls. A sunlight-readable display. Answers in seconds — no signal needed.
Cited answers
Every value and every AS/NZS clause comes from a deterministic calculation engine — never guessed. The optional assistant explains results in plain language; it never invents a value or a clause.
Fully offline
Works on site with no signal. Nothing leaves your device. No account. No internet required for calculations or the AI assistant. Everything runs on your iPhone.
Metric, your way
mm², metres, 230 V / 400 V, 50 Hz — guided forms, a fast keypad, or just ask in plain language. Three entry modes, one calculation engine.
Everything on the wiring rules ticket
Built around AS/NZS 3000 and AS/NZS 3008.1.1 cable selection. Pick your edition. Get cited results.
Voltage drop
Enter load, length, conductor, and system voltage — WireMind Pro returns the drop in volts and as a percentage of supply, with the relevant clause cited.
Conductor area
Calculate the minimum cross-sectional area in mm² for your circuit. Enter current and length; the engine handles AS/NZS 3008 cable selection arithmetic.
Ohm's law & power
Solve for voltage, current, resistance, or power from any two known values. Live as you type, with unit conversion between common electrical units.
Cable current-carrying capacity
Table-based CCC per AS/NZS 3008.1.1:2025. You enter the AS/NZS 3008 table value from your copy of the standard; the app applies installation and temperature correction.
Maximum demand
Assess the maximum demand for a circuit or sub-board per the wiring rules diversity factors — rolling out with the AS/NZS 3000 calculation suite.
Protective devices & earthing
Size fuses, circuit breakers, and earth conductors per AS/NZS 3000 / AS/NZS 3008. Part of the rolling calculation suite.
Projects & PDF export
Save calculations to named projects. Export clean, cited PDFs — every result includes the standard edition and clause so your documentation is complete.
Pick your AS/NZS edition
Supports AS/NZS 3000:2018, 2007, 2000, and 1991. Switch editions per project so calculations match the standard applicable to the job.
On-device assistant
Optional. Uses Apple's on-device foundation model — your prompts are processed on your iPhone, not sent to any server. Turns plain-language requests into calculator inputs.
Data Not Collected
- All calculations run on your device — inputs, results, and projects stay on your iPhone and are never sent anywhere.
- The AI assistant is on-device. Apple's on-device foundation model processes your prompts locally; nothing is uploaded.
- No accounts, no analytics, no advertising, no trackers.
- Voice input (if used) is transcribed on-device using Apple's speech recognition — audio is not uploaded.

WireMind Pro is a calculation aid. It does not replace the AS/NZS 3000 standard, a licensed electrician's judgement, or your electrical safety regulator.
