The only reason I think this is relevant, is because as the price of copper wiring is high, the use of aluminum wiring is becoming more common. It's used for almost all service wiring, and it's often used for hookups for electric ranges and a/c units or anything else that uses 220. Rrostie (talk) 05:56, 12 June 2010 (UTC)
