What is the specified length for #4/0 AWG conductors?

Explanation:
Length of a conductor run is governed by voltage drop and allowable resistance. The bigger the conductor, the lower the resistance per foot, so you can run it farther before you exceed the voltage‑drop limit. For #4/0 AWG, the resistance per foot is small enough that the table specifies a run length in the 85–105 ft range. That keeps voltage drop within tolerance for typical currents on site equipment. Shorter ranges correspond to smaller gauges with higher per-foot resistance, which would limit how far you can run the wire.
