Answer / ankit trivedi
TO SELECT PROPER BUSBAR WE SHOULD KNOW THE LOAD CURRENT &
CROSS-SECTION AREA OF THE MATERIAL WHICH IS GOING TO BE
USED. IE CU OR AL.
I.e A CU. BUSBAR OF 25x6 Sq.mm. WILL CARRY THE CURRENT AS
BELOW
25X6 = 150 (cross section area)
150X1.6 =240A
THE BUS BAR OF 25X6mm. WILL CARRY 240A CURRENT, WHERE 1.6
IS GLOBLE SAFTY FACTOR.
