Changes in v1.4.2

  • Voltage Drop Upsizing Detection: The Calculation Trace Engine now detects when a conductor is upsized above its base thermal requirement ( \ge I_n$) solely to satisfy allowable voltage drop limits (IEC 60364-5-52 §525 / NEC 210.19(A)).
  • Voltage Drop Upsizing Gate Step: Adds a dedicated mathematical step showing the base thermal size, the excessive voltage drop at that size over the circuit length, and the upsized cable size that brings the voltage drop within compliance.
  • Trace Parameters Provenance: Displays \Sizing Governing Factor: Voltage Drop, \Base Thermal Requirement, \Circuit Route Length, and \Calculated Voltage Drop (ΔU).
  • Clarified Compliance Margin: Explains continuous margin above $ in the trace compliance banner as a consequence of voltage drop upsizing.
  • Full Internationalization: Added English, Arabic, German, and Italian translations for all new trace labels, parameters, and margins.
  • Build & Tests: All 720 tests pass across 60 test files; production build verified with Next.js Turbopack.
