Q MCM is the abbreviation for 1 kcmil. problem for a de?nition of cmil.) Data for commercial-base aluminum electrical conductors list a 60-Hz resistance of 0.0880 /km at 75°C for a 795-MCM conductor.
(a) Determine the cross-sectional conducting area of this conductor in m2.
(b) Calculate the 60-Hz resistance of this conductor in /km at 50°C, given a temperature constant of 228.1°C for aluminum.
