The size of earth pin is longer and bigger because of only
two reason as per British standard 1363
• The longer earth pin ensures that the earth path is
connected before the live pins, and remains connected after
the live pins are removed.
• The design of the earth pin being of a larger
dimension prevents it from being inserted into the phase or
neutral sockets should this be attempted in error.

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.
