Usually, where I'm at anyway, the power company installs the transformer and the service drop or lateral. We just take over from there with the service entrance conductors and service equipment. The power company usually connects their equipment to ours. We do, however, some large commercial jobs where we stub the underground service entrance conductors out of the ground. Then the power company puts there transformer on top of those and makes the final connection. They put a lock on that equipment when they leave. So I would say if you want 240/120 1-phase or 208/120 3-phase you would have to order that service from the power company.
