Aluminum Wire

American cable Gauge

The table below lists the Aluminum cable Characteristics for different gauges the the American cable Gauge .

You are watching: 4/0 aluminum wire weight per foot

The American cable Gauge offers a way of specifying cable diameters.For each different AWG the table provides;the Diameter , Diameter , the resistance every 1000 foot, the Fusing current, and also Pounds per Foot .Read the notes below the table to determine just how the Ampacity to be derived. The larger the AWG number, the smaller sized diameter wire.The table is based upon an approximately temperature of 25oC. Conductor dimension is based one or more of the complying with considerations:Current transferring capacity , short circuit current, or Voltage autumn .

Table of bare Aluminum Wire

Notes:For the very same conductivity aluminum cable is about two gauges bigger than copper wire.The table over only list the AWG standard. The wire size is different in between the American cable Gage and the british standard.AWG may additionally be dubbed the Brown and also Sharpe (B&S) cable Gauge.The Birmingham cable Gauge is supplied for steel armor wire.Watch for round-off errors, as countless numbers to be rounded. Usage the table together a guide.The load does not encompass wire insulation. The weight of the wire is an essential in part applications.Circular mils is the diameter squared in mils.The cable fusing existing is based upon the material the wire is make of, the diameter the the wire and also the melting point of the the material. The wire fusing current of a wire is noted in tables as consistent current or together current for some provided amount of time.I discovered this formula used on a few different website ; I=Ad(3/2)
d is in inches, A is a constant: A = 10,244 because that Copper. A = 7,585 for Aluminum.I have noted a variety of values for fusing existing in the table above, because that selected AWG sizes.Copper wire properties are noted under top top the Copper electrical Wire page. Manufacturers listing for electric Wire and also Cable.
