WebA = 2 ⋅ l ⋅ I γ ⋅ U a. Single-phase AC wire calculation: A = 2 ⋅ l ⋅ I ⋅ cos φ γ ⋅ U a. Three-phase AC (three-phase current) line cross-section formula: A = 3 ⋅ l ⋅ I ⋅ cos φ γ ⋅ U a. The formulas for the cable cross-section look quite complicated at first glance. WebWhat size wire for 15 amps? To safely use a maximum current of 15 amps, you will need a wire gauge of 14. A 12 gauge wire is a safer bet, but a 14 gauge wire will work just fine.
