I have an installation in which the customer upgraded the size of his generator. I have installed a triplex "stephens" ALUM 2 awg, 7 strand, .403 inches. I have it buried under 36" in direct earth. The ampacity from the manufacturer states that it is good for 165 amp based on the NEC 2005. I need 145 amps. The length of the cable is 175'.
Can someone walk me through the NEC Calculation to determine the ampacity of the wire? I am unclear going through 310 on how to properly calculate the ampacity.
Thanks
