Voltage DropResistance value of 1 wire per 2002 NECsets of
wiressets of wiresVoltage Drop CalculationsThe following voltage
drop calculations were all based on the resistance values in Table
8 of Chapter 9 of the 2002 NEC. This spreadsheet only considers
voltage drop. Many other factors affect wire size. Refer to the
