Wire Size Calculator Electrical Wire Gauge Calculator for DC Circuits
To use the calculator, enter the Maximum Current in Amps of the circuit, and the Length of the Wire, and operating Voltage. Typically most automotive systems run at 13.8V, but you can select 6, 12, 13.8 (Default) or 24 volts. If the wire gauge is OK to use it will have a 'Check Mark' on the same line. For example, let's calculate the wire size of a 100-meter-long copper wire for a single-phase circuit when it must supply 30 amps of current with a 10 V voltage drop allowed: A (mm²) = 2 × 1.7241×10-8 Ω·m × 100 m × 30 A / 10 V × 1,000,000 A (mm²) = 10.3446×10-6 m² × 1,000,000 A (mm²) = 10.3446 mm². By comparing the size to the list of AWG wire sizes in the chart below, we can. To use this DC and AC wire size calculator: Choose the DC/AC Single-phase option for the electrical system. Input 12 V for the source voltage. Enter 2% for the allowable voltage drop (V). Select copper for the conductor material. Type in 2 A for the current (I). Enter 0.3 m for the one-way distance (D). The n gauge wire resistance R in ohms per kilometer (Ω/km) is equal to 1000000000 times the wire's resistivity ρ in ohm-meters (Ω·m) divided by the cross sectional area An in square millimeters (mm2): Rn (Ω/km) = 10 9 × ρ(Ω·m) / An (mm2) See also AWG to mm calculator SWG to mm calculator Voltage drop calculator Inches to mm converter

Calculate Your Voltage Drop Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run. When sizing conductors, calculations limits wire size to voltage drop and NEC ampacity. Southwire's Voltage Drop Calculator is designed for applications using AWG and KCMIL sizes only. Wire size calculation formulas. DC calculation of line cross section: A = 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.
