TrueFault: Fault Current Calc

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.
