wire sizing

Best answer


Wire is sized by theAmerican Wire Gauge (AWG) system. Wire gauge refers the physical size of the wire,rated with a numerical designation that runs opposite to the diameter of the conductors鈥攊n other words,the smaller the wire gauge number,the larger the wire diameter. Common sizes include 14-,12-,10-,8-,6-,and 2-gauge wire.

  • What is wire size calculator?

  • The American Wire Gauge (AWG) system adopted in 1857 has defined a method for electrical wire size calculator. The method has two basic objectives, that is, the ratio of the largest size with the smallest size would be an integer. The second goal, the resulting gauges would generally correspond to the proprietary gauges used at the time.

  • What is the smallest wire size?

  • The larger the AWG number or wire guage, the smaller the physical size of the wire. The smallest AWG size is 40 and the largest is 0000 (4/0). AWG general rules of thumb – for every 6 gauge decrease, the wire diameter doubles and for every 3 gauge decrease, the cross sectional area doubles.

  • What are the factors to consider when determining the wire size and wire specifications?

  • The current ratings of the power loads is the factor that is to be considered when determining the wire size and wire specifications. If the current is fast and the wire size small, the wire will get heated up too soon.

  • What is a wire gauge?

  • American Wire Gauge Conductor Size Table American wire gauge (AWG) is a standardized wire gauge system for the diameters of round, solid, nonferrous, electrically conducting wire. The larger the AWG number or wire guage, the smaller the physical size of the wire.
