The direction of conventional current is defined as the
direction of the flow of positive charges.Later,the charge
carriers were found to be electrons,posistrons ,or both in
opposite directions.In metal conductors the positive
charges are immobile and only 'negatively charged'electrons
flow.Because of electrons carry 'negative charge',the
electron motion in a conductor is the direction opposite to
that of conventional current.This convention ,though may
seem outdated ,is used worldwide.

My question is whether bellow formula is correct to find bus size for 46kA for 0.5 second & what is RT in bellow formula. formula to calculate the size of busbar to withstand the thermal stresses due to currents with duration of 0.2 sec to 5 sec. Sp = RT( I x I x t) / K Where Sp – is the cross sectional area of bus bar in millimeters. I - is the value of AC fault current. t - is the operating time of disconnecting device in seconds. K – is the factor depending on the material of the conductor, insulation and initial and final temperature. Value of ‘k’ for copper is 143.
