This tool calculates the maximum cable length that can be used without exceeding the allowable voltage drop and without degrading insulation, based on IEC and NEC standards. It supports DC, single-phase, two-phase, and three-phase systems, including parallel conductors and various temperature rating
This tool calculates power losses (I²R losses) in cables due to conductor resistance during current flow, based on IEC and NEC standards. It supports DC, single-phase, two-phase, and three-phase systems, including parallel conductors and various insulation types. Input Parameters 1.Current Type: Dir
This tool calculates the maximum admissible let-through energy (I²t) that a cable can withstand under short-circuit conditions, based on IEC 60364-4-43 and IEC 60364-5-54 standards. It ensures that protective devices (e.g., circuit breakers or fuses) interrupt fault currents before the conductor ove
Calculate derated ampacity of low-voltage insulated conductors (≤1 kV) per IEC 60364-5-52. Accounts for ambient temperature, harmonics, multiple circuits, and parallel conductors. When You Need This Calculation Selecting cable size for a 400V three-phase motor feeder Verifying if existing wiring can
This tool calculates the maximum symmetrical short-circuit current at the output of a transformer substation, based on IEC 60865 and IEEE C37.100 standards. Results are essential for selecting circuit breakers, fuses, busbars, and cables, as well as verifying equipment’s short-circuit withstand capa
