Example Stranded conductor 19/2.9 mm. calculate the equivalent diameter of conductor. Solution: The diameter of one strand (d) = 2.9 mm No. of stranded in conductor (Ns)=27 Therefore for No. of layer = 2, distributed as follow: = [1 + 6+ 12] core 1st layer 2nd layer

Electrical wiring is the way of integrating cables and wires to interconnected equipment such as fuses, switches, sockets, lights, fans, and so on to the main distribution board, which is a specific structure attached to the utility pole that ensures a c…
