About this app

The developer's US App Store description, in full.

Work through available fault current with a clear calculation trail. TrueFault helps electrical contractors enter source and transformer data, build the path to the equipment, and review the result with its inputs, assumptions, and warnings in view. START WITH SINGLE-PHASE — FREE Follow five steps: System, Source, Transformer, Path, and Result. Enter known primary available fault current, or review the default infinite-primary assumption. Add conductor and bus runs, choose the fault point, and see the calculated available fault current in amps and kA. SEE HOW THE SYSTEM CONNECTS Review a visual one-line from the source through the transformer and path to the equipment. Open calculation details to inspect impedance and contributions. Keep project names, equipment names, source references, and field notes with your calculation. TRUEFAULT PRO — ONE PURCHASE Unlock Pro permanently with a one-time in-app purchase. There is no subscription or recurring charge. Pro adds: • Three-phase fault-current calculations. • Motor contribution inputs. • Saved projects and reusable default settings on this device. • Label and calculation report tools, with print and share actions when the calculation's review requirements are met. • Local report history for returning to previous work. The App Store displays your local price before purchase. Restore an eligible Pro purchase with the same Apple Account. KEEP YOUR WORK CLOSE Calculations run on your device. No TrueFault account is required. Projects, settings, and report history stay on this device unless you export or back them up separately. TrueFault is a calculation aid for qualified electrical professionals. Verify the source data, equipment ratings, installation conditions, applicable requirements, and results before use. It does not replace a stamped engineering calculation or an arc-flash study.
