Sample / draft. The numbers below are an illustration, not a project.
The example
NEC® 2023 is the edition for this example. A 200 A continuous load at 480 V, copper, 90 °C insulation, 30 °C ambient, and three current-carrying conductors sizes to one set of 250 kcmil. The termination check uses the 75 °C column. Voltage drop on 200 ft in steel conduit at 0.90 power factor is about 1.03% by the Chapter 9 Table 9 effective-impedance method.
Ze = R·PF + XL·sin(arccos PF)
