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. In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electric current) in one or more directions. Materials made of metal are common electrical conductors. Electric current is generated by the flow of negatively charged electrons, positively charged holes, … See more The resistance of a given conductor depends on the material it is made of, and on its dimensions. For a given material, the resistance is inversely proportional to the cross-sectional area. For example, a thick copper See more Conduction materials include metals, electrolytes, superconductors, semiconductors, plasmas and some nonmetallic … See more The ampacity of a conductor, that is, the amount of current it can carry, is related to its electrical resistance: a lower-resistance conductor can carry a larger value of current.
