Does anyone know where I can get a good price on 200 amp copper wire (underground to hook up electricity to a doublewide. Hot#2 Copper, Ground #4Copper and Neutral #2 Copper. 330-350 feet Thanks
At that distance, you would be better with aluminum wire. BUT: #2 copper is 0.156 ohm/1000 feet. You have 700 feet, so the is a resistance of 0.11 ohms. At 200 amps, that is a drop of 22 volts, much too high. Requirement is 5% drop, and at 120 volts, that is 6 volts. #2 copper would be good for 55 amps only at that distance. .
