10.2 Guide for engine-driven generators in submersible pump applications
Note:
• The table is based on typical +176 °F (+80
°C) rise continuous duty generators with 35
% maximum voltage dip during startup of
single-phase and three-phase motors.
• Contact the manufacturer of the generator to
make sure the unit has adequate capacity to
run the submersible motor.
• If the generator rating is in KVA instead of
kilowatts, multiply the above ratings by 1.25
to obtain KVA.
