Fault Current Calculator (PFC) vs Show Works Ltd

Fault Current Calculator for iPhone and iPad is a fast, free tool for electricians, contractors, and engineers. Calculate Prospective Fault Current (PFC), Prospective Short-Circuit Current (PSCC), and Prospective Earth Fault Current (PEFC). Enter any two known values - voltage, loop impedance (Zs/Ze), or fault current - and the app instantly calculates the third. KEY FEATURES: PSCC and PEFC calculations: Calculate prospective short-circuit current for L-N or L-L faults and prospective earth fault current for L-E faults. Single-phase and three-phase support: Perform fault-current calculations for both system types. Automatic calculations: Enter any two known values to auto calculate the third. Loop-impedance calculator: Calculate Zs or Ze from voltage and prospective fault current. Formula display: See the formula used for each calculation so you can understand and verify the result. Works offline: Use the app in roof spaces, basements, plant rooms, and other locations without a signal. Dark mode and light mode: Maintain a clear display in different site conditions. 16 languages: Fully translated for electricians worldwide (af, ar, de, es, en, fr, hi, id, it, ja, ko, nl, pl, pt, ru, zh). Fast and free: A clean interface designed to deliver results without unnecessary steps. DEFINITIONS: AIC (Ampere Interrupting Capacity), often written as kAIC for kilo-Amperes, is a specific rating for protective devices that open a circuit, such as circuit breakers and fuses. SCCR (Short-Circuit Current Rating) is the maximum fault current that a complete piece of equipment or electrical assembly (like an industrial control panel, switchboard, or HVAC unit) can safely withstand without causing a hazard. Electrical calculations should be independently verified before safety-critical work. Ensure the calculated prospective fault current does not exceed the protective device's rated breaking capacity. For additional tools, upgrade to Electrical Tools & Reference, which includes calculators for kVA, Max Zs, cable sizing, and more. Pro Certs Software - trusted by electricians since 2011.
