1. Introduction JCALC (Joule Heating Calculation) refers to the analytical process of determining the minimum permissible cross-sectional area of an electrical cable based on thermal limits, voltage drop, and short-circuit withstand capability. Proper cable sizing is critical to prevent insulation degradation, fire hazards, and unacceptable system losses.
