Copper’s superior thermal and electrical conductivity, combined with its 100% recyclability make copper a truly green material perfect for building a sustainable world.
Copper is the standard benchmark for electrical conductivity. It conducts electrical current better than any other metal except silver. Copper is routinely refined to 99.98% purity (even more pure than Ivory Soap) before it is acceptable for many electrical applications.Number 12 (AWG) copper wire is the most common size used for branch circuit wiring in buildings. The amount of copper products consumed in the U.S.A. this past year would make a size 12 wire that could encircle the Earth 2,630 times or make 140 round trips to the Moon.CDA’s Electrical Energy Efficiency program illustrates how a simple upsizing of copper conductors used for electrical distribution can earn significant paybacks to building owners, usually within one to two years
