It's really not a question of how big the overhead service cable is because the power company rates their wire a whole lot different than the NEC (Code).

If I would have let them use wire which was too small the church would have had very high voltage when their demand was small and very low voltage when their demand was high. Lights would burn out with high voltage and motors would burn up when the voltage was low.
