Product Information

Electric resistance in wire made of Copper, Aluminum, Brass, Constantan, Nichrome, Platinum, Silver or Tungsten. The AWG - American Wire Gauge - is used as a standard method denoting wire diameter, measuring the diameter of the conductor (the bare wire) with the insulation removed. AWG is sometimes also known as Brown and Sharpe (B&S) Wire Gauge.

Somehow we don't see ourselves nonchalantly calculating this in our heads every time we speak with an American customer, so we've made up a conversion table which we'd like to share for your convenience. AWG # When buying cut to length electrical wire or electrical cable, many UK and international buyers face difficulty when confronted with AWG sizing. Vice Versa, American buyers may be stumped when they are recommended a certain gauge of cable or wire, and don't know how to get it when confronted with mm.

Type THHN/THWN-2 building wire is intended for general purpose applications as defined by the National Electrical Code (NEC). 4 AWG THHN-THWN-2 is permitted for new construction or rewiring for 600-volt applications. Applications requiring Type THHN or THWN-2, the conductor is appropriate for use in wet or dry locations at temperatures not to exceed 90°C or not to exceed 75°C in oil or coolants. Applications requiring Type MTW conductor is appropriate for use in dry locations at 90°C, or not to exceed 60°C in wet locations or where exposed to oils or coolants. Applications requiring Type AWM conductor is appropriate for use at temperatures to not exceed 105°C in dry locations. Values for resistance are based on electrical resistivity for copper 1.724 x 10 -8 Ω m (0.0174 μΩ m) and electrical resistivity for aluminum 2.65 x 10 -8 Ω m (0.0265 μΩ m).

Commonly, when you refer to the size of a conductor, you talk about its cross-sectional area, which is expressed in mm2. To calculate the cross-section of solid round wires, you can use this formula: In this system, 0000 AWG indicates a wire diameter of 0.46 inches, and 36 AWG indicates a wire size of 0.005 inches. There are 39-gauge sizes between these two sizes which you can get through logarithmic calculations. The ratio of different sizes is 1 to 92 in diameter. So, you can say that each AWG step is around the 39th root of 92, which is approx. 1.12293 times changes in diameter. Note! - the diameter of a solid and stranded wire with the same AWG is not identical. The diameter of a stranded wire is larger than the diameter of a solid wire. Calculate the number of small circles that fits into an outer larger circle - ex. how many pipes or wires fits into a larger pipe or conduit.Color-coded Polyvinyl Chloride (PVC), heat and moisture-resistant, flame-retardant compound per UL-1063 and UL-8 4 AWG THHN/THWN-2 Specifications*: AWG Notes: American Wire Gauge (AWG) is a standardized wire gauge system used predominantly in the United States to note the diameter of electrically conducting wire. The general rule of thumb is for every 6 gauge decrease the wire diameter doubles and every 3 gauge decrease doubles the cross sectional area.
