Equation for current through awg wire
By definition, Nr. 36 AWG is 0.005 inches in diameter, and Nr. 0000 is 0.46 inches in diameter, or nearly half-an-inch. The ratio of these diameters is 1:92, and there are 40 gauge sizes from the smallest Nr. 36 AWG to the largest Nr. 0000AWG , or 39 steps. Each successive gauge number decreases the wire diameter by a constant factor. Any two neighboring gauges (e.g., AWG A and AWG B ) have diameters whose ratio (dia. B ÷ dia. A) is while for gauges two steps apart (e.g., … Web= Iwire (A) × (2 × L(ft) × Rwire(Ω/kft) / 1000 (ft/kft)) The voltage drop V in volts (V) is equal to the wire current I in amps (A) times 2 times one way wire length L in meters (m) times the wire resistance per 1000 meters R in ohms (Ω/km) divided by 1000: Vdrop (V) = Iwire (A) × Rwire(Ω) = Iwire (A) × (2 × L(m) × Rwire (Ω/km) / 1000 (m/km))

WebMay 14, 2024 · Conductor sizes are expressed in American Wire Gauge (AWG), typically from 18 AWG up to 4/0 AWG. Conductor sizes larger than 4/0 AWG are expressed in kcmil (thousand circular mils) [Sec. 110.6]. There’s a misconception that 12 AWG copper is the smallest conductor permitted for commercial or industrial facilities. WebExample – 6 AWG copper wire in 180 feet of iron conduit–3 phase, 40 amp load at 80% power factor. Multiply feet by amperes: 180 x 40 = 7200 Multiply this number by number from table for 6 AWG wire three-phase at 80% power factor: 7200 x 745 = 5364000 Multiply by 1 5364000 x 1 = 5364000 #/phase 1
WebJul 13, 2024 · AWG Wire Sizes (see chart below) AWG: In the American Wire Gauge (AWG) system, wire size diameters can be calculated by applying the formula D (AWG)=.005·92 ( (36-AWG)/39) inch. For the 00, 000, 0000 etc. gauges you use -1, -2, -3, which makes more sense mathematically than "double nought."
