"Breaking capacity of a busbar refers to the maximum electrical load it can carry before failing or breaking due to overloading. It is calculated based on factors such as cross-sectional area, material properties, insulation type and thickness, mechanical stresses, thermal stresses, and temperature rise under load. The most common methods for calculating the breaking capacity are the Ampacity method (based on current density) and the Creep method (based on time-dependent deformation)."n
