    You should use whatever size wire your foreman or supervisor tells you to use.

    1200 Amps 277/480 volt run at 1500 feet?

    Even I will not touch this.

    Seriously, this needs engineering.

    Or bring the high voltage 1450 feet, then change over to 480/277 volt.

Sizing parallel conductors [ 2 Answers ]

On a 400 amp service for a commercial building. I'm trying to figure out the conductor size using parallel runs. I think 3/0 is sufficient but not sure. 3/0 is good for 225amps under the 90 degree column. Do you then multiply by 2 for 450 amps?
