    Conversion using the Busbar Current Calculation Formula

    The Busbar Current Capacity Formula can be expressed as:

    The is a simplified method to calculate the current-carrying capacity (ampacity) of a busbar. Here's a breakdown of the components:

    Ibb = W × T × MF

      Where:

    • Ibb = Busbar current capacity (Amps)
    • W = Width of the busbar (mm)
    • T = Thickness of the busbar (mm)
    • MF = Material Factor (depends on conductor type: copper or aluminum)

    Typical Material Factors (MF):
