Most larger businesses run higher 240 voltages, because they use
3-phase power.  3-phase is far more efficient for large amperage
circuts than the standard 2-phase we all normally use.  Also, 3-phase
is a no-brainer for generator motors, due to the 3 poles on such
motors.

Google-up to learn more about 3 phase power.
