Voltage Drop Single Phase
Single Phase Voltage Drop
This calculation is one which is important if a load is 120 volt and more
than 50 feet from the source of power, and also important if the load is 240
volt and more than 100 feet from the course of power.
The algebra formula for voltage drop is:
Vd = (2 X k X I X L) divided by cm
Where:
X means times
Vd equals voltage drop in volts
2 is for there and back of a single phase circuit
k is the constant calculated by R times cm divided by 1000
I is the actual current the load will draw
L is the distance in feet the load is located from the source
