WHAT IS THE THUMBRULE FOR FINDING OUT THE CURRENT CAPICITY
OF A COPPER WIRE?? 2.5, 4, 6MM SQUARE ETC...
Answer Posted / uttam dutta
cURRENT CARRYING CAPACITY NOT ONLY DEPENDS ON THE CROSS
SECTION OF THE COPPER WIRE, IT ALSO GREATLY DEPENDS UPON
THE TYPE AND THICKNESS OF THE INSULATION, ONE MORE FACTOR
IS CORE OF THE CABLE, IE SINGLE CORE OR MULTICORE.
cONSIDERING ALL THIS FATORS STRICTLY IT CAN BE SAID 1 SQ.
MM COPPER CABLE CAN BEAR MAX.11 AMP SAFELY CONTENIOULY AND
2.R CAN BEAR 19 AMP . 4 SQ MM CAN BEAR 26 AMP. SOME TIME
THIS MAY VARY LITTLE DEPENDING UPON MAKE.
