I need to do a service drop (single phase - 3 wire type XHHW - copper)cable.
Because of a daily summer time temp of 113 (F) I need to factor the correction 0.82 into the calculation.
Based on the math I did, I would need a 1350 kcmil copper cable (300 Amps) to feed 246 amps after the correction. 300 X 0.82 = 246 amps. Question, do I have to use a 300 Amp breaker or a 250 Amp breaker?
Thanks in advance
