What will be the Vd for the 12AWG copper conductor which will be used to install a load 179.6 Ft away from the service panel? Assume that the load takes a power of 1KW and a Voltage of 208VAC
To find the voltage drop (Vd) for a 12AWG copper conductor, we can use the formula:
Vd = (2 * K * I * L) / CM
Where:
- Vd is the voltage drop in volts (V)
- K is the resistivity constant for copper (10.4)
- I is the current in amperes (A) (1KW / 208VAC = 4.80A)
- L is the length of the conductor in feet (179.6 ft)
- CM is the cross-sectional area of the conductor in circular mils (12 AWG corresponds to approximately 6533 circular mils)
Substituting the values into the formula:
Vd = (2 * 10.4 * 4.80 * 179.6) / 6533
Vd = 13.941 volts (V)
Therefore, the voltage drop for a 12AWG copper conductor used to install a load 179.6 ft away from the service panel is approximately 13.941 V.
