BY SIMPLE
CURRENT DENSITY = LOAD CURRENT/AREA
FOR COPPER OR ALUMINIUM CURRENT DENSITY CAN BE VARIED ACCORDING TO OUR DESIGN.FOR GOOD DESIGN CURRENT DENSITY SHOULD BE REDUCED WHICH HELPS IN EASY TEMPERATURE DISSIPATION.
CONSIDER CURRENT DENSITY OF 0.6A/SQ.MM FOR cu OR AL
LOAD CURRENT-100A
THEN
0.6=100/AREA
AREA=166 SQ.MM
MEAN THAT 166 SQ.MM REQUIRED TO CONDUCT 100A.
