Product Information

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 The number of devices connected to the circuit usually determines how much current will flow through the 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 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″. 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 The wire size chart below shows allowable ampacities of insulated conductors rated up to and includingBy 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. In the US, the most commonly used wire gauge system is AWG, or American Wire Gauge. The higher the gauge number, the smaller the wire. 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. The n gauge wire resistance R in ohms per kilometer (Ω/km) is equal to 1000000000 times the wire's resistivity ρ in

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 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 wireThe U.S. wire gauges (called AWG gauges) refer to sizes of copper wire. This table corresponds to a resistivity of 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. Results may change with real wires: different resistivity of material and number of strands in wire For more information regarding wiring and cables, see our comprehensive guide here. AWG Gauge Table AWG gauge AWG is also commonly used to specify body piercing jewelry sizes (especially smaller sizes), even when the material is not metallic. [2] Formulae [ edit ]
