"Usually, three copper wires come into the home. Two are covered in black insulation and one has white insulation. Sometimes one wire is red instead of black. Each black or red wire is called a 'hot' wire and has 110-volt AC. The white wire is called the 'common' and is grounded at the power station." 9-03
