KW = ROOT3*VI*PF/1000
65=1.732*400*I*0.9/1000
I=104
MCCB 1.5 TIMES THE AMPS
SO MCCB SELECT 160 AMPS
CABLE 70 SQ MM CU OR 120 AL

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.
