Product Information

The largest diameter AWG size is 0000 (4/0) which is pronounced ‘four aught’, representing a diameter of .46″. The smallest diameter is 32 AWG, representing .00795″. The n gauge wire resistance R in ohms per kilofeet (Ω/kft) is equal to 0.3048×1000000000 times the wire's resistivity ρ in By definition, No. 36 AWG is 0.005 inches in diameter, and No.0000 is 0.46inches in diameter. The ratio of these diameters is 1:92, and there are 40 gauge sizes from No.36 to No.0000, or 39 steps. Because each successive gauge number increases cross sectional area by a constant multiple, diameters vary geometrically. Any two successive gauges (e.g., A and B ) have diameters whose ratio (dia. B ÷ dia. A) is 92 39 {\displaystyle {\sqrt[{39}]{92}}} (approximately 1.12293), while for gauges two steps apart (e.g., A, B, and C), the ratio of the C to A is about 1.12293 2 ≈ 1.26098. AWG is also commonly used to specify body piercing jewelry sizes (especially smaller sizes), even when the material is not metallic. [2] Formulae [ edit ]

The AWG gauge system only applies for solid, round, non-ferrous conducting wires. Keep this in mind when evaluating wire size and type for your application, as AWG doesn’t apply to stranded or non-round wires. AWG Gauge Sizes for Home Wiring, Auto Wiring, and Boat Wiring The AWG system states areas of round copper wires in "circular mils", which is the square of the diameter in mils. 1 mil =.001 inch. This table uses this value of resistivity, but it is known to vary by a few percent based on purity and process of manufacture. AWG wire Maximum current for chassis wiring. Data from Handbook of Electronic Tables and Formulas for American Wire Gauge. The maximum current for power transmission is less.The n gauge wire diameter d n in inches (in) is equal to 0.005in times 92 raised to the power of 36 minus gauge number n, divided by 39: The common U.S. wire gauges (called AWG gauges) refer to sizes of copper wire. The resistivity of copper at 20 C is about d n = 0.005 i n c h × 92 ( 36 − n ) / 39 = 0.127 m m × 92 ( 36 − n ) / 39 {\displaystyle d_{n}=0.005~\mathrm {inch} \times 92

for copper at 20 C. This table uses this value of resistivity, but it is known to vary by a few percent based on purity and process of manufacture. While the AWG is essentially identical to the Brown & Sharpe (B&S) sheet metal gauge, the B&S gauge was designed for use with sheet metals as its name suggests. These are functionally interchangeable but the use of B&S in relation to wire gauges, rather than sheet metal gauges, is technically improper. The n gauge wire diameter d n in millimeters (mm) is equal to 0.127mm times 92 raised to the power of 36 minus gauge number n, divided by 39:The wire size chart below shows allowable ampacities of insulated conductors rated up to and including
