I'm taking a code book class and we where going over the optional method for calculating a dwelling service. The answer was set to a 93 amp feeder. You said to go to the 75?C column to size your wire. I thought that you had to go to the 60?C column because it is under 100 amps. Please tell me if I am wrong and a explanation of who it would be figured at the higher degree c. Thank you Mark Snodgrass February 3 2016, 8:42 pm EST Reply to this comment |
