The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F).

Useful info: # = American Wire Gauge (AWG), the lower the number the larger the wire guage. "Service cable" is large insulated stranded copper cable (usually refers to single #4 wire and up).

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.

AWG Wire size chart and ampacity table for design engineers including skin depth frequencies and tensile strength data; electrical cable size

In this AWG wire gauge chart for a standard copper wire, you can find every AWG wire; from the biggest 10+ mm wires (such as 4/0 AWG and 3/0 AWG wires) to the smallest below 0.01 mm wires like 39 and 40 AWG wires.

2024年8月2日 · If you're buying wires by size in inches or millimeters, or have stripped and measured uninsulated wires with a gauge tool, you can also use a wire gauge chart to determine the maximum amperage of a wire. Most charts provide ampacity for copper and aluminum wire and their most common insulation materials.

In these AWG gauge charts, most common gauge values show the different characteristics of wire such as its diameter, area, ampacity, resistance, current density, fusing current and temperature ratings etc.

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 .

2023年12月16日 · Here is the table that comes with different values, like the resistance of wire gauges and the current value for copper conductors with plastic insulation. The diameter details in the table are for solid wires. Standard wires are measured by measuring the equivalent cross-sectional copper area. Read Also: What 18 Gauge Wire Used For?

AWG is sometimes also known as Brown and Sharpe (B&S) Wire Gauge. The AWG table below is for a single, solid, round conductor. Because of the small gaps between the strands in a stranded wire, a stranded wire with the same current-carrying capacity and electrical resistance as a solid wire, always have a slightly larger overall diameter.
