WebMicrometer is used to measure the diameter of wires/conductors in circular mils. It can measure small and big sizes of wires and cables. Wire Gauge is used in determining the size of wires/conductors. The gauge ranges from 0 to 60 awg (American wire gauge) 30. what is the size of the conductor or wire if the amperage rating is 30 amps? Answer: WebNov 15, 2016 · How to find the cross sectional area of a wire First, we define that the diameter of our wire is taken in thousandths of an inch where one one-thousandth of an inch is called “one mil.” Thus, 0.001 inch = 1 …

WebWhat is the circular mil area of a round conductor with a diameter of 25 mils? Solution A= d2 = 252 = 635 c.mils A = d 2 = 25 2 = 635 c .mils A circular mil-foot, as demonstrated in figure 2, is, in reality, a volume … WebThe correct answer is: 500 mils = circular mil area → VII., 10 mils = circular mil area → II., 0.1020 inch = circular mil area → V. To find the approximate resistance of a given copper conductor, drop the ? digit from the circular mil area. The result is the number of ? per ohm. last / feet WebA solid cylindrical aluminum conductor 25 km long has an area of 336,400 circular mils. Obtain the conductor resistance at 20C and 50C. Find the AC resistance per Km of the cable at 50C. Assume a skin-effect correction factor of 1.02 at 50 Hz. The resistivity of aluminum at 20C is 2.8x10-8 Ωm phillip weaver
