To determine the approximate resistance of a 500 kcmil uncoated copper conductor per 1000 feet, it is essential to refer to standard tables or formulas that provide the resistivity of copper conductors. The resistance of a conductor can typically be calculated using the formula:

[

R = \frac{\rho \cdot L}{A}

]

where (R) is the resistance in ohms, (\rho) is the resistivity in ohm-feet, (L) is the length of the conductor in feet, and (A) is the cross-sectional area in circular mils.

For uncoated copper, the resistivity is approximately 10.4 ohm-cmil/1000 feet. Since we are dealing with a 500 kcmil conductor, we can substitute the values into the formula.

Calculating the resistance for 1000 feet at 500 kcmil involves looking at the dataset specific to copper conductors. For a 500 kcmil uncoated copper conductor, the typical resistance is around 0.0258 ohms per 1000 feet. This value aligns with standard resistance values found in electrical reference tables.
