The editor has never reviewed the American Wire Gauge standard. More data Ĭircular mils is the diameter squared in mils. The weight of the wire is critical in some applications for example, aircraft cabling. The wire weight provided does not include wire insulation, a jacket or any shielding as that would imply a cable and not a wire. Watch for round-off errors, as many numbers were rounded. The Birmingham Wire Gauge is used for steel armor wire, as opposed to copper wire. The table above only lists the AWG standard.ĪWG may also be called the Brown and Sharpe (B&S) Wire Gauge, but would be an extremely out-dated reference. The wire size is different between the American Wire Gage and the British standard. AWG Wire Table, AWG Copper Wire Gauge Chart AWG Conductor size is based one or more of the following considerations:Ĭurrent carrying capacity, Short circuit current, or Voltage drop. Refer here for a quick guide to Wire Gauge by Resistance Table.Ī listing of Electronic bus standards are located on the Buses page.Īnother table near the bottom of the page provides copper current carrying ability for Teflon Interface Buses are #22AWG, #24AWG, #26AWG, and 30AWG. Some of the standard wire sizes used in a number of However the next link provides additional temperatures. The table is based on an ambient temperature ofĢ5 oC. The larger the AWG wire gauge number, the Read the notes below the table to determine how the Ampacity was derived. The AWG is based upon a constant ratio of cross-section between wires of successive gauge sizes.
The current carrying capability, and Pounds per Foot [number The American Wire Gauge provides a means of specifying wire diameters.įor each different AWG the table provides the Diameter, the resistance per 1000 foot, The table below lists the wire characteristics for different gauge sizes of
