Tabulated AC voltage drop calculations for quick reference can be found here: Alternating Current Voltage Drop Calculation Table, or calculate the exact voltage drop here: AC Voltage Drop Calculator. Adjustments for temperatures above or below 30☌ can be found in NEC Table 310.15(B)(1). Table 310.16 is applicable up to 2,000 volts with an ambient temperature of 30☌ (86☌). Note: a neutral is a current-carrying conductor while the grounding conductor(s) are not. The reason is the inherent practicality and breadth of installations covered by “…Insulated Conductors with Not More Than Three Current-Carrying Conductors in Raceway, Cable, or Earth (Directly Buried)”. Table 310.16 is one of the most commonly used tables in the National Electrical Code.
