American wire gauge (AWG) size calculator and chart. * @ 68°F or 20°C. ** Diameter and cross sectional area do not include the insulation. *** Results may change with real wires: different resistivity of material and number of strands in wire. Voltage drop calculator .

Wire Size Ampacity & Breaker Size Charts Based on AWG. Derived from the wire gauge chart and based on AWG sizes, the following fig shows the commonly used wire gauge size for different applications. Click image to enlarge

Enter the information below to calculate the appropriate wire size. Voltage - Enter the voltage at the source of the circuit. Single-phase voltages are usually 115V or 120V, while three-phase voltages are typically 208V, 230V or 480V. Amperes - Enter the maximum current in amps that will flow through the circuit.

2024年9月4日 · The American Wire Gauge system defines standards for wire gauges to help ensure you know which size wire you’re working with. We’ll explain wire gauges, why they matter and show you an example of a wire gauge chart.
