Workflow

Compares standard conductor sizes using calculated load current, R+X voltage drop, an editable current-density criterion and the adiabatic short-circuit thermal expression S ≥ I√t/k.

Important limitations

Current-density screening is not a code ampacity table. Installation method, ambient temperature, grouping, protective-device coordination, harmonics, conductor insulation and local electrical rules still govern final cable sizing.

Scope & assumptions

Preliminary engineering workflow — verify final design with the applicable standards, project data and manufacturer information.
