Real Voltage Drop (Single)

Single point voltage drop calculator that solves for conductor gauge, voltage drop, maximum length and maximum load. The calculator implements the method given in ANSI/IEEE Standard 141, 1993 - "Calculation of Voltage Drops" and uses the formula for exact voltage drop. Many other calculators use an approximate method. The AC resistance and reactance values are from NEC Ch. 9, table 9 and the DC resistance values are from Ch. 9, table 8.

Singe point calculators are ineffective when multiple loads are sequentially added to a circuit (typical in lighting circuits), please see Real Voltage Drop (Series) for those applications.

The app can output the result in an email.
