Recommended Wire Gauges by Scale

Note: Recommended Wire Gauges Shown in Table Are For Copper Wire Only, at 60 Hertz, AC, Sine wave. Keep that in mind when making comparisons. This chart is based on a 5A maximum current on the bus. For a 10A booster, move to the next larger gauge (smaller number). Runs up to 100 feet are possible with 12AWG wire, and 50 feet with 14AWG. This is for one leg, in theory it is possible to have a 100 foot run (14AWG) with the booster in the middle (50 feet on each side). Don't skimp on wiring, plan of future power needs.
