Voltage drop ground wire calculator
The voltage drop V in volts V is equal to the wire current I in amps A times 2 times one-way wire length L in meters m times the wire resistance per 1000 meters R in ohms Ωkm. Ohms Law is a very basic law for calculating voltage drop.
When sizing conductors calculations.
. Larger wire less voltage drop Phases. Enter a value for the source voltage eg 12 V. Choose from aluminum or copper wire.
Calculates maximum length of conductor run voltage drop and voltage at load based on voltage phases amps wire size conductor and maximum percentage drop. I have a single 120V 20A circuit for some exterior lighting. Voltage Drop WL x 2 x R x LC 1000.
