Wire Size for 5.48 Amps
Typical copper wire gauges for 5.48 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. At 5.48A the load sits in residential-branch territory where aluminum is not a typical conductor, so the table lists copper only. Actual install sizing depends on conductor material, insulation/termination temperature rating, cable type, ambient and bundling derates, and local code.

Copper gauges use the NEC 240.4(D) branch-circuit cap, not raw 75°C ampacity.
