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

Electrical current is measured in amps. Each wire size, or wire gauge (AWG), has a maximum current limit that a wire can handle before damage occurs. It is important to pick the correct size of wire so that the wire doesn't overheat. The number of devices connected to the circuit usually determines how much current will flow through the wire.

The AWG tables and charts are handy methods to specify the current carrying capacity of a conductor, its diameter, resistance, max current in amperes and other important parameters and characteristics.

Typical household wiring is AWG number 12 or 14. Telephone wire is typical AWG 22, 24, or 26. The table below indicates the current ratings of PVC-insulated single and multicore wiring cables. Be aware that the current load depends on installation method - the enclosure - and how well the resistance heat is removed from the cable.

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.
