The calculation of cable current rating (often referred to as ampacity) is a critical step in electrical system design. It determines the maximum continuous current a conductor can carry without exceeding its temperature rating. Exceeding this limit causes the insulation to degrade, leading to short circuits, fire hazards, and system failure. The basic equation for current rating (based on
