Note: Above table is based on extensive study of popular bus-bar sizes used to terminate Air Circuit Breakers. However other bus-
bar sizes (in terms of thickness & width) can also be used to achieve bus-bar cross section recommended by IS & IEC.
De-rating of switchgear depends upon various factors such as cross section area, orientation and material of bus bar, healthiness
of bus-bar joints, panel construction, and ventilation, etc.
