Made conductor resistivity dependent on the wire insulation temperature rating.
Resistivity increases with temperature. The used conductor resistivity was optimistically low (corresponding to 20degC). To be more conservative, the resistivity is now chosen higher, corresponding to 75degC, roughly conform NEC chapter 9, tables 8 and 9. So for a given max allowable voltage drop, the required wire will be larger.
Opening the sheet in Google drive corrupted it.
