Calculating Voltage Drop for a 540 Foot Run of Coated 4/0 Copper

What is the approximate voltage drop for a 540 foot run of coated 4/0 copper at 480 volts, single phase with a load of 200 amps?

How can we determine the voltage drop in this scenario?

Final Answer:

The voltage drop can be calculated using Ohm's Law.

To calculate the voltage drop for a 540 foot run of coated 4/0 copper at 480 volts with a load of 200 amps, we can utilize Ohm's Law. Ohm's Law states that the voltage drop (V) is equal to the current (I) multiplied by the resistance (R).

The resistance can be determined using the formula: R = ρ * L / A, where ρ is the resistivity of copper, L is the length of the wire, and A is the cross-sectional area of the wire.

Once the resistance is calculated, we can find the voltage drop by multiplying the current (200 A) by the resistance. By following these calculations, we will arrive at the approximate voltage drop for the specified scenario.
