Availability depends on your utility and location. It's not uncommon for a farm to have 3-phase service--it's needed for things like hay dryers. For example, here's my rural electric co-op's rate sheet for 3-phase service: https://laneelectric.com/wp-content/uploads/GS-3-General-Service-Three-Phase-Eff-1-1-20.pdf By way of comparison, here's their single-phase general-service rate sheet: https://laneelectric.com/wp-content/uploads/GS-1-General-Service-Single-Phase-Eff-1-1-20.pdf The real sting is for 3-phase electric vehicle charging stations: https://laneelectric.com/wp-content/uploads/EV-1-Electric-Vehicle-Charging-Station-Eff-1-1-20.pdf In my rural location, 3-phase 11KV buried is available at a disconnect box at the street--single phase is buried along the driveway and terminates at a transformer on a pad in my front yard. Buried 240/120V single-phase 200A service then goes to the house. --Chuck
