Wire Size for 182.83 Amps
Typical copper and aluminum wire gauges for 182.83 amps across common run lengths on a 120V circuit, sized to keep voltage drop under 3% and respect the NEC 240.4(D) small-conductor rule. Actual install sizing depends on conductor material, insulation/termination temperature rating, cable type, ambient and bundling derates, and local code.

| 300 ft | 500 kcmil | 750 kcmil | 2.83V (2.36%) | OK |
| 400 ft | 750 kcmil | no aluminum pick | 2.5V (2.08%) | OK |
| 500 ft | 750 kcmil | no aluminum pick | 3.13V (2.61%) | OK |
Aluminum is not typical for 10 AWG and smaller branch-circuit conductors in residential settings. Copper gauges use the NEC 240.4(D) branch-circuit cap, not raw 75°C ampacity.
