Which AWG size corresponds to a length of 67-84 ft?

Explanation:
The key idea here is how conductor size is chosen to keep voltage drop within acceptable limits as distance increases. In the AWG charts used for site power and feeder runs, longer lengths mean more resistance along the path. To keep the voltage drop from exceeding the allowable limit, you select a larger conductor (lower resistance per foot). For a run in the 67–84 ft range, the chart specifies a three-aught (3/0) AWG size, which provides enough cross-sectional area to keep the drop within spec for the expected current. So, among the options, 3/0 AWG is the size associated with that length range on the chart.
