The handbook didn't pretend aluminium was copper. Instead, it told a story: In 1972, a substation in Gujarat failed because an engineer used copper lugs on an aluminium bar. Galvanic corrosion ate the joint in six months. Indal’s solution wasn't magic—it was discipline. Bi-metallic washers. Joint compound. Correct torque. Anjali realized: aluminium didn't fail. People failed aluminium. Instead, it told a story: In 1972, a

Aluminium has a lower melting point than copper (660°C vs 1085°C). Consequently, the design for short-circuit withstand is different. The Indal Handbook offers the simplified for busbar sizing under fault:
