Circular mil area of conductor
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 Webcircular mils Conductors are expressed in AWG numbers from 18-4/0. Wire sizes larger than 4/0 are expressed in circular mils. ... The rating of the overcurrent device determines the rating of the branch circuit. ... The load must not exceed the branch circuit rating ... An individual branch circuit may supply any size load ...

WebThe actual area of a Circular Mil is: A =Pi x r². A = 3.14159 x (.0005)² inches. A = .0000007857 square inches. When wires get very large their sizes are sometimes shown as "MCM", such as 250MCM. MCM means … 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
