However, AWG is dissimilar to IEC 60228, the metric wire-size standard used in most parts of the world, based directly on the wire cross-section area (in square millimetres, mm 2). The AWG tables are for a single, solid and round conductor. The AWG of a stranded wire is determined by the cross-sectional area of the equivalent solid conductor.
Standard sizes are from 250 to 400 in increments of 50 kcmil, 400 to 1000 in increments of 100 kcmil, and from 1000 to 2000 in increments of 250 kcmil. [ 6 ] The diameter in the table below is that of a solid rod with the given conductor area in circular mils.
Each diameter was multiplied by 0.890526 to give the next lower size. This is now the American wire gauge (AWG), and is prevalent in North America and used to some extent in over 65 countries, with a market share of about 30% of all power and control wires and cables. [3]
Also, the size of the aluminum wire needs to be larger compared to copper wire used for the same circuit due to the increased resistance of the aluminum alloys. For example, a 15 A branch circuit supplying standard lighting fixtures can be installed with either #14 AWG copper building wire or #12 AWG aluminum building wire according to the NEC ...
In residential construction, branch circuits for higher ratings are usually dedicated to one appliance, for example, fixed cooking appliances, electric clothes dryers, and air conditioners. Lighting and general purpose receptacles are at 120 volts AC, with larger devices fed by three wire single-phase circuits at 240 volts.
The Birmingham gauge ranges from 5/0 or 00000, the lowest gauge number corresponding to the largest size of 0.500 inches (12.7 mm), to 36, the highest gauge number corresponding to the smallest size of 0.004 inches (0.10 mm).
Cooking With Convection Since convection ovens work so fast, the foods don't have to be cooked for as long a time as in conventional ovens. Plus the temperature can be set lower, at about 25 ...
In North America bird names are used for the code words while animal names are used elsewhere. For instance in North America, Grosbeak is a 322.3 mm 2 (636 kcmil) ACSR conductor with 26/7 Aluminium/Steel stranding whereas Egret is the same total aluminium size (322.3 mm 2, 636 kcmil conductor) but with 30/19 Aluminium/Steel stranding. Although ...
