ScubaDan, he stated it's in PVC. Without knowing anything else, it's standard to assume 75C. PF would have to be taken into account, but an assumed PF of 1.0 is always going to be safe. Honestly, a PF of .85-.9 is probably not going to make a difference in the cable size used, but it could be taken into account if the result is borderline and he really wants to justify using a smaller kcmil cable.
