14.2 Choosing A Pump System
A typical well application can be set up using one of three
electrical configurations for single-phase power. The
samples below are based upon a system using a 1.5 HP,
20-22 gpm pump, with 400 feet of wire from electrical
disconnect to the motor. All configurations shown are
suitable methods for residential applications.
