This app calculates prospective fault current (PFC) in kA and Amps for single and three-phase circuits. It allows users to input any two values (voltage, earth loop impedance, or PFC) to determine the third, aiding in selecting appropriate circuit breaker ratings.
This tool helps contractors, engineers, and electricians quickly calculate available fault current on single and three-phase electrical systems. It also assists in sizing fuses and conductors for various circuits and can generate labels for service equipment.
