#4/0 Aluminum URD cable is typical for this size service and distance. This type of cable is rated to be direct buried,usually in a trench 30 inch deep with 6 inch of sand below the cable and 6 inch of sand on top of the cable, then backfill with the natural material up to grade level.Also need a warning tape above the cable 6 - 12 inch below grade.
Assuming the main breaker is at the meter, then 4 wire cable is needed.
URD (Undergound Residential Distribution)cable, will consist of two black #4/0 wires for the hots,one #2/0 for the neutral and a #4 for the equipment ground.
Any section of the cable's path under pavement will require a conduit sleeve under the paved area, usually 3 inch PVC Sch 40 or DB conduit.
