Since 1996 new homes are required under Article 550.16(A)(2) of the National Electrical Code (NEC) 2008, the dryer outlet shall be installed with a 4 wire electrical supply so that the neutral and ground wires are separated and not carried on the same wire.

Electric dryers require 220 volts and the wire used to supply the dryer receptacle should be 10 gauge wire rated to carry 30 amps.

10-3 wire will have one red wire(hot), one black wire(hot), one white wire(neutral), and a bare copper ground wire.

Important!!! Make sure the electric is turned off to the dryer receptacle.
