    Copper or aluminum conductors? Are you sleeving it in pipe, direct burying it, ariel? And that's a pretty far run explain your situation to us.

    120V? I think you mean 120/240V.

    Don't tell me that for one second you were considering just 120V for such a job.

    I am sure the poster does not realize a standard residential service is 120/240 volts, or simply two 120 volt legs.

    The installation, based on the listed loads, sounds like a hunting cabin, or similar.

    I would suggest using #4/0 aluminum wire, using a 4 wire direct burial cable called URD. This can be buried directly in ground, using 6 inches of sand below and above. Being such a long distance, for additional protection, I would suggest using 4 inch Sch40 PVC conduit as a sleeve.

    You will need to splice #2 wire onto the #4/0 to reduce the wire size at the panelboard, as the lugs will not accept the #4/0 wire.
