The Aluminum Electrical Conductor Handbook lists a dc resistance of 0.01558 ohm per 1000 ft at 20C and a 60-Hz resistance of 0.0956 ohm per mile at 50C for the all-aluminum Marigold conductor, which has 61 strands and whose size is 1113 kcmil. Assuming an increase in resistance of 2 for spiraling, calculate and verify the dc resistance. Then calculate the dc resistance at 50C, and determine the percentage increase due to skin effect.
